Annapurna Trekking Deaths 2026: Quick Answer
Twenty-five tourists died in the Annapurna region during fiscal year 2025/26, according to the Annapurna Conservation Area Project (ACAP). Most deaths were caused by altitude sickness, not avalanches or technical climbing accidents. Fifteen deaths occurred in Mustang, eight in Manang, one at Annapurna Base Camp, and one on the Mardi Himal trail.
With proper acclimatization, a licensed guide, and awareness of early warning symptoms, the Annapurna Circuit and Base Camp routes remain safe for well-prepared trekkers. Annapurna has carried a fearsome reputation for decades, and the numbers coming out of Nepal this July have put that reputation back in the headlines.
But the real story behind the latest data is not the one most people expect. The region’s newest death toll has almost nothing to do with avalanches, crevasses, or technical climbing routes. It comes down to something far more preventable: altitude and how trekkers respond to it.
Every trekking season, thousands of visitors arrive in Pokhara with the same plan: walk into the Annapurna range, see the peaks up close, and come home with photographs that do not do the mountains justice. Most of them succeed without incident. A small number do not, and the reasons why are far more predictable than most people assume.
This article walks through the official 2025/26 numbers from the Annapurna Conservation Area Project, breaks down exactly where and why trekkers are dying, separates the trekking risk from the climbing risk that gives Annapurna its fearsome name, and lays out what actually reduces your risk if you are planning a trek in this region.
Annapurna Region Death Toll: Fiscal Year 2025/26 Numbers
How Many Trekkers Died This Year
ACAP recorded 25 tourist deaths from altitude sickness in the Annapurna Conservation Area during fiscal year 2025/26. That figure comes directly from ACAP chief Dr. Rabin Kadariya, and it does not include the additional five deaths recorded in the same period from falls and other trekking-related accidents, bringing the region’s total trekking-related toll closer to 30.
Nationality Breakdown of the Deceased
Of the 25 altitude sickness deaths, 12 were Nepali nationals, nine were Indian, and one each came from Japan, Mexico, Spain, and Singapore. Among the Nepali deaths, four were trekking guides and porters, a detail that matters because it shows altitude sickness does not discriminate based on local experience or familiarity with the terrain.
Where the Deaths Happened: Mustang, Manang, ABC, and Mardi Himal
The distribution of deaths across the region is uneven, and it tells its own story about where risk concentrates on the Annapurna route network.
| Location | Deaths (FY 2025/26) | Primary Cause |
| Mustang | 15 | Altitude sickness |
| Manang | 8 | Altitude sickness, one snowfall-related death |
| Annapurna Base Camp | 1 | Altitude sickness |
| Mardi Himal Trail | 1 | Altitude sickness |
| Other accidents (region-wide) | 5 | Falls and trekking accidents |
Mustang and Manang together account for 23 of the 25 altitude sickness deaths, more than 90 percent of the total. Both districts sit on high-altitude sections of the Annapurna Circuit, where trekkers cross elevations above 4,000 m in a short window of days.
How This Year Compares to Recent Seasons
Annapurna region fatality figures fluctuate year to year, shaped by trekker volume, weather patterns, and how strictly acclimatization guidance is followed in any given season. What has stayed consistent across recent reporting periods is the ranking of causes: altitude sickness first, falls and weather-related accidents a distant second, and technical climbing accidents last.
The FY 2025/26 numbers fit that same pattern, which suggests the underlying risk profile of the Annapurna trekking route has not fundamentally changed, even as total trekker numbers continue to grow year over year.
Why the Real Toll Is Likely Undercounted
ACAP’s figures reflect deaths that are formally reported and registered within its conservation area jurisdiction. Independent trekkers who skip registration checkpoints, medical emergencies resolved after evacuation to Kathmandu or Pokhara hospitals, and cases where cause of death is recorded differently by hospital staff can all fall outside a single year’s official count.
Most researchers who study Himalayan trekking mortality treat official regional figures as a reliable floor rather than a precise ceiling, which is one more reason not to treat the 25 to 30 figure as the full picture of risk on the route.
What Is Actually Killing Trekkers on the Annapurna Route
Altitude Sickness: The Number One Killer
Acute mountain sickness and its more severe forms, HAPE (high altitude pulmonary edema) and HACE (high altitude cerebral edema), remain the leading cause of death on the Annapurna route by a wide margin. Unlike avalanche or crevasse deaths, altitude sickness deaths are almost always preventable with proper pacing, hydration, and a willingness to turn back or descend when symptoms appear.
The underlying mechanism is straightforward physiology. Air pressure drops as elevation increases, which means each breath delivers less oxygen to the bloodstream. The body can adapt to this, producing more red blood cells and adjusting breathing rate, but that adaptation takes time, typically several days at each new elevation band.
Trekkers who gain altitude faster than their body can adjust are the ones who develop AMS. Push through those symptoms and keep climbing, and mild AMS can progress within hours into HAPE, where fluid builds up in the lungs, or HACE, where fluid builds up around the brain. Both conditions can be fatal without rapid descent.
Recognizing the Warning Signs Before They Become Emergencies
AMS symptoms are easy to dismiss as ordinary trekking fatigue, which is exactly why so many cases progress further than they should. The table below separates mild, early-stage symptoms from the danger signs that indicate a medical emergency requiring immediate descent.
| Stage | Common Symptoms | Recommended Action |
| Mild AMS | Headache, mild nausea, fatigue, loss of appetite, poor sleep | Stop ascending, rest at current altitude, hydrate, monitor symptoms |
| Moderate AMS | Worsening headache, vomiting, dizziness, shortness of breath at rest | Descend at least 300 to 500 m; do not continue ascending under any circumstances |
| Severe (HAPE) | Breathlessness at rest, cough, gurgling in the chest, blue lips or fingertips | Immediate descent and emergency evacuation, supplemental oxygen if available |
| Severe (HACE) | Confusion, loss of coordination, inability to walk a straight line, drowsiness | Immediate descent and emergency evacuation are treated as a life-threatening emergency |
Falls, Weather, and Accidental Deaths
Five deaths in the same period came from falls and other trekking accidents rather than altitude illness. One Indian tourist died during a heavy snowfall event while trekking in Manang, and an Australian climber died while descending from Himlung Himal, also in Manang district. These cases point to a second layer of risk: sudden weather changes and technical terrain, particularly around high passes and off-route peaks.
Guides and Porters Among the Victims
Four of the Nepali deaths were guides and porters, a reminder that altitude sickness risk applies to local staff as well as foreign trekkers. It reinforces why reputable trekking companies train guides to recognize AMS symptoms in themselves and their crew, not only in clients.
Is Annapurna Really the World’s Deadliest Mountain? Trekking Risk vs Climbing Risk
Annapurna I’s Summit Fatality Rate in 2026
Annapurna I, the eighth-highest mountain on earth at 8,091m, has a long-standing reputation as the deadliest 8,000m peak. That reputation comes from historical data. Between 1950 and 2006, the mountain’s cumulative fatality-to-summit ratio sat near 38.7 percent. By 2012, it had fallen to roughly 31.9 percent. As of February 2026, with around 559 summits and 75 deaths recorded, the ratio has dropped to approximately 13.4 percent.
Why the 40 Percent Death Rate Headline Is Outdated
The 40 percent figure still circulating online reflects expedition conditions from the mid-twentieth century, before modern weather forecasting, fixed rope systems, satellite communication, and helicopter rescue were part of the standard mountaineering practices. Citing that number today, without the historical context, significantly overstates the current risk for a 2026 expedition.
Trekking Annapurna Circuit and Base Camp vs Climbing Annapurna I
This is the distinction most casual readers miss. Annapurna I is a technical 8,000m expedition climb, attempted by a small number of experienced mountaineers each year. The Annapurna Circuit and Annapurna Base Camp treks are entirely different undertakings, walking routes that do not require climbing skills or supplemental oxygen. The 2025/26 death toll of 25 to 30 people comes almost entirely from the trekking side of the region, driven by altitude sickness among walkers, not from climbing accidents on Annapurna I itself.
Annapurna I vs Other 8,000m Peaks: Fatality Rate in Context
Annapurna I still carries one of the highest fatalities-to-summit ratios among the world’s 14 eight-thousand-meter peaks, even after decades of improvement, but the gap between it and mountains like Everest is frequently exaggerated in popular coverage. The table below places Annapurna I’s 2026 rate alongside commonly cited figures for other major peaks to give the comparison proper context.
| Peak | Approx. Fatality to Summit Ratio (2026) | Primary Risk Factors |
| Annapurna I (8,091m) | ~13.4 percent | Avalanches, unstable ice, technical descent |
| Everest (8,849m) | Under 2 percent | Traffic jams at altitude, exhaustion, exposure |
| K2 (8,611m) | Historically higher, improving | Technical climbing, avalanches, remoteness |
| Manaslu (8,163m) | Moderate | Avalanches and crowding on the summit push |
The pattern across all of these peaks is similar to Annapurna’s: modern forecasting, fixed rope infrastructure, and faster rescue response have brought fatality ratios down substantially from where they stood in the twentieth century, even though headlines and casual comparisons still lean on the older, scarier numbers.
High Risk Zones on the Annapurna Route
Mustang and Upper Mustang Altitude Risk
Mustang recorded the highest death count in the region this year, with 15 altitude sickness deaths. Upper Mustang’s rain shadow terrain means trekkers often gain altitude quickly on relatively easy, dry trails, which can create a false sense of security. The physical ease of walking does not reduce the physiological risk of ascending too fast.
Manang and the Approach to Thorong La Pass
The Manang district, home to the approach towards Thorong La Pass at 5,416 m, recorded eight altitude sickness deaths plus additional weather and accident-related fatalities. This stretch of the Annapurna Circuit is where trekkers make their final push over the route’s highest point, often on a tight schedule that leaves little room for extra acclimatization if symptoms appear.
Annapurna Base Camp and Mardi Himal Trail Risk Factors
Annapurna Base Camp, at 4,130m, and the Mardi Himal trail each recorded one altitude sickness death this year. Both routes are shorter and lower in maximum elevation than the full Annapurna Circuit, which generally makes them lower risk, though altitude sickness can still occur at these elevations, especially with rapid ascent profiles.
How Annapurna’s Trekking Risk Compares to Everest and Manaslu
Annapurna Region vs Everest Base Camp Route
The Everest Base Camp route benefits from what is likely the most developed rescue and medical infrastructure of any trekking corridor in Nepal, including a well-known high-altitude aid post in Pheriche staffed during trekking seasons. The Annapurna Circuit and Base Camp routes have their own registration checkpoints and, in Manang, a seasonal aid post of their own, but the network is not identical in density to the Khumbu.
That difference does not make Annapurna inherently more dangerous. Both regions post altitude sickness-related deaths most years, and both carry similar underlying risk once trekker volume and route elevation profile are accounted for.
Annapurna Region vs the Manaslu Circuit
The Manaslu Circuit is a restricted area requiring a special permit and a licensed guide by law, in part because of its more remote terrain and thinner rescue coverage compared to Annapurna. Manaslu’s route also crosses the Larkya La pass at over 5,000 m, similar in profile to Thorong La on the Annapurna Circuit, and carries comparable altitude-related risk. Trekkers considering either route should apply the same acclimatization principles regardless of which valley they choose.
What This Means If You Are Choosing Between Routes
None of Nepal’s major trekking regions is meaningfully safer than the others once you control for how well a given itinerary handles altitude gain. The deciding factor for your own safety has far less to do with which valley you pick and far more to do with how many days your itinerary allows for acclimatization and whether your guide has the authority and training to call a turnaround when needed.
Nepal’s Safety Response: What ACAP and the Government Are Doing
Trekker Registration and Checkpoints
Following the 2014 Annapurna Circuit disaster, Nepal introduced mandatory trekker registration at checkpoints along major routes, giving authorities a way to track who is on the trail and flag overdue trekkers faster than in the past. ACAP permits and TIMS cards are the backbone of this system in the Annapurna Conservation Area.
Aid Posts and Seasonal Medical Coverage
Manang hosts a seasonal high-altitude aid post that offers guidance and basic assessment to trekkers heading toward Thorong La, staffed during the busiest trekking windows in spring and autumn. These posts are not full hospitals, and their existence is not a substitute for proper acclimatization, but they do provide an early checkpoint where deteriorating trekkers can be identified before they continue higher.
Helicopter Rescue Networks
Private helicopter operators based in Pokhara and Kathmandu provide the backbone of emergency evacuation for the Annapurna region, and most licensed trekking companies maintain direct contact with these operators for rapid dispatch. Response time depends heavily on weather, since helicopters cannot always fly in poor visibility or high wind, which is one more reason early recognition of AMS symptoms matters more than fast evacuation after the fact.
Ongoing Gaps ACAP’s Own Data Points To
The fact that four of this year’s deceased were guides and porters suggests training gaps still exist even among trekking staff, not only among foreign visitors. Advocacy groups and some guide associations in Nepal have continued to push for mandatory, standardized AMS recognition training as a condition of guide licensing, an area where enforcement still varies between operators.
Notable Annapurna Incidents That Shaped Today’s Safety Rules
The October 2014 Thorong La Storm
The single deadliest event in Annapurna Circuit history remains the October 14, 2014 storm, when the remnants of a cyclone collided with a regional weather system and dropped roughly 1.8 meters of snow on Thorong La Pass within 12 hours. At least 43 trekkers died, with some estimates suggesting the true number of unrecovered trekkers may have been higher, and more than 400 people required helicopter rescue in what became the largest helicopter evacuation the Himalayas had seen to that point.
The disaster exposed a lack of centralized weather warnings and a guide culture that, at the time, did not always have the authority to turn clients back against flight schedules or group pressure. Nearly every safety reform introduced on the Annapurna Circuit since traces back to this single event.
2023 Annapurna I Expedition Season
The spring 2023 climbing season on Annapurna I drew national and international attention after a well-known Irish mountaineer died while descending from the summit and, separately, an Indian climber fell into a crevasse on the same mountain during the same window. Both incidents occurred during a period of heavy expedition traffic and generated renewed scrutiny of crowding, rope fixing schedules, and supplemental oxygen use on the route, issues that mirror conversations happening on Everest during the same era of rising commercial expedition numbers.
What These Events Have in Common
Every major Annapurna incident of the past decade, whether on the trekking side or the technical climbing side, traces back to one of two root causes: a weather system that arrived faster than the response system could react to, or a decision to continue ascending despite warning signs. Neither cause is unique to Annapurna, and both are exactly what modern acclimatization planning, guide training, and weather monitoring are designed to catch before they become fatal.
How to Trek Annapurna Safely in 2026
Build In Proper Acclimatization Days
The single biggest factor separating a safe trek from a dangerous one is pacing. Ascending gradually, with dedicated rest and acclimatization days built into the itinerary, gives the body time to adjust to reduced oxygen levels before pushing higher. The widely used guideline among Himalayan trekking doctors is to limit net sleeping altitude gain to roughly 300 to 500m per day once above 3,000m, with a full rest day scheduled every 900 to 1,000m of cumulative gain.
| Elevation Band | Recommended Daily Gain | Acclimatization Guidance |
| Below 3,000m | No strict limit | Normal trekking pace; stay hydrated |
| 3,000m to 4,000m | 300 to 500m per day | Consider a rest day near 3,500 m. |
| 4,000m to 5,000m | 300m per day | Rest day recommended before any pass crossing |
| Above 5,000m | Minimal further gain | Cross passes early in the day; descend same day if possible |
Learn to Recognize Early Symptoms of Altitude Sickness
Headache, nausea, dizziness, and loss of appetite are early warning signs of AMS. These symptoms are the body’s signal to stop ascending, not to push through. Recognizing them early and responding by resting or descending is what prevents mild AMS from progressing to life-threatening HAPE or HACE.
Why a Licensed Guide Reduces Your Risk
A licensed guide trained in altitude sickness recognition can identify symptoms in trekkers who may be reluctant to admit they are struggling and has the authority and experience to make a turnaround call before a situation becomes an emergency. Trekking with a licensed guide is standard practice on the Annapurna route and required in several restricted areas.
Get Travel Insurance With Helicopter Evacuation Coverage
Given that a majority of this year’s fatalities were altitude sickness-related and that helicopter evacuation is often the fastest way to get a symptomatic trekker to lower elevation and medical care, travel insurance that specifically covers high-altitude helicopter rescue is essential, not optional, for any Annapurna trek.
A Pre-Trek Preparation Checklist
A short amount of preparation before you ever set foot on the trail materially reduces your risk of a serious altitude-related incident. Consider the following non-negotiables before booking or departing on an Annapurna trek.
| Preparation Step | Why It Matters |
| Book an itinerary with built-in acclimatization days | Prevents the single biggest driver of AMS deaths: ascending faster than the body can adjust |
| Confirm your guide is licensed and AMS trained | Ensures someone on the trek has the authority and knowledge to call a turnaround |
| Buy travel insurance with helicopter evacuation up to 6,000 m. | Covers the realistic worst-case scenario on a high-pass route |
| Get a basic medical check before departure | Identifies pre-existing heart or lung conditions that raise altitude risk |
| Pack a pulse oximeter | Gives an objective, early read on blood oxygen saturation as you gain altitude |
| Carry Diamox (acetazolamide) after consulting a doctor | A commonly used preventive medication for AMS, taken only under medical guidance |
| Avoid alcohol and sleeping pills above 3,000 m. | Both can mask symptoms or suppress breathing during sleep at altitude |
How Mountain World Treks Manages These Risks
Acclimatization: First Itinerary Design
Every Mountain World Treks itinerary on the Annapurna route is built around gradual ascent and dedicated acclimatization days rather than the fastest possible schedule, directly addressing the leading cause of death identified in ACAP’s own data.
Guide to Trekker Ratios and Emergency Protocols
Groups are kept at guide-to-trekker ratios that allow close monitoring of every member’s condition, with clear emergency descent and evacuation protocols in place before any trek begins.
Years of Guiding Experience
Mountain World Treks was founded by Saligram Aryal, who brings years of guiding experience across Nepal’s major trekking regions, including the Annapurna route network, to the design and supervision of every itinerary.
Annapurna Trekking Deaths 2026: Frequently Asked Questions
How many people died on the Annapurna trekking route in 2025/26?
ACAP recorded 25 tourist deaths from altitude sickness in the Annapurna region during fiscal year 2025/26, plus five additional deaths from falls and other trekking accidents, for a combined total of about 30.
What is the leading cause of death on the Annapurna Circuit?
Altitude sickness, including its severe forms HAPE and HACE, is the leading cause of trekker deaths on the Annapurna Circuit, far ahead of avalanches, falls, or technical climbing accidents.
Which part of the Annapurna region has the highest number of trekker deaths?
Mustang recorded the highest number of deaths this year, with 15 fatalities, followed by Manang with eight.
Is the Annapurna Base Camp trek dangerous for beginners?
Annapurna Base Camp is considered moderate in difficulty and reaches 4,130m, lower than the full Annapurna Circuit. It recorded one altitude sickness death in FY 2025/26 and remains safe for well-prepared beginners who follow a gradual acclimatization schedule with a licensed guide.
What is the death rate on Annapurna I compared to Everest?
As of 2026, Annapurna I’s summit fatality rate is approximately 13.4 percent, down from historical highs near 38 to 39 percent. Everest’s fatality rate is lower, generally cited under 2 percent per successful summit.
How many people have died at Thorong La Pass?
There is no single official cumulative death count specific to Thorong La Pass, though the pass was the site of Nepal’s worst trekking disaster in October 2014, when a sudden storm caused at least 43 deaths across the wider Annapurna Circuit.
Is the Annapurna Circuit trek safe in 2026?
Yes, for trekkers who acclimatize properly, trek with a licensed guide, and carry evacuation-focused travel insurance. The region’s fatality rate relative to the tens of thousands of trekkers who complete the route each year remains below 1 percent.
Do I need a licensed guide to trek Annapurna?
A licensed guide is required in restricted areas of the Annapurna region and strongly recommended everywhere else. Guides trained in altitude sickness recognition can identify early symptoms and make critical turnaround decisions.
What should I do if I experience altitude sickness symptoms?
Stop ascending immediately, rest, and if symptoms do not improve or worsen, descend to a lower elevation. Severe symptoms such as confusion, loss of coordination, or breathlessness at rest require immediate descent and emergency evacuation.
What is ACAP, and what role does it play in trekker safety?
ACAP, the Annapurna Conservation Area Project, manages the Annapurna Conservation Area, issues trekking permits, and tracks and reports on tourist deaths and safety incidents across the region.
How many foreign tourists died in the Annapurna region this year?
Thirteen of the 25 altitude sickness deaths were foreign nationals, including nine Indians and one each from Japan, Mexico, Spain, and Singapore. The remaining 12 were Nepali nationals.
Are trekking guides and porters also at risk of altitude sickness?
Yes. Four of the Nepali deaths recorded this year were trekking guides and porters, showing that local staff are not immune to altitude sickness despite their experience on the route.
What is the difference between the Annapurna Base Camp trek and the Annapurna Circuit trek in terms of risk?
Annapurna Base Camp tops out at 4,130m over a shorter route, while the Annapurna Circuit crosses Thorong La Pass at 5,416m over a longer, higher itinerary. The circuit generally carries the greater altitude-related risk due to its higher maximum elevation.
How does the Annapurna death rate compare to historical data?
Annapurna I’s fatality-to-summit ratio has fallen steadily, from about 38.7 percent between 1950 and 2006 to 31.9 percent by 2012 to roughly 13.4 percent as of early 2026, reflecting improved logistics, forecasting, and rescue infrastructure.
What time of year has the highest risk of altitude sickness deaths on Annapurna?
Spring and autumn are peak trekking seasons with the highest trekker volume, and altitude sickness risk tracks closely with the number of people ascending quickly during these windows.
Can altitude sickness be prevented on the Annapurna trek?
In most cases, yes. Gradual ascent, adequate rest days, proper hydration, and avoiding alcohol at altitude significantly reduce the risk of developing AMS.
What altitude does Thorong La Pass reach, and why is it risky?
Thorong La Pass sits at 5,416m, the highest point on the Annapurna Circuit. Its risk comes from the combination of extreme altitude, exposure to sudden weather changes, and a long single push day with limited descent options.
Is Manang or Mustang more dangerous for trekkers?
Mustang recorded more total deaths this year, 15 versus eight in Manang, though both districts carry significant altitude-related risk due to their elevation and position on the circuit’s high-altitude sections.
What emergency services are available on the Annapurna trekking route?
Helicopter evacuation is available from most points along the Annapurna Circuit and Base Camp routes, along with checkpoint-based trekker registration and, in Manang, an altitude sickness aid post that offers guidance to passing trekkers.
How much does travel insurance for the Annapurna trek typically cost?
Cost varies by provider, trip length, and maximum altitude covered, but insurance with helicopter evacuation coverage up to at least 6,000m is considered essential for the Annapurna Circuit.
What permits are required to trek in the Annapurna Conservation Area?
Trekkers need an Annapurna Conservation Area Permit (ACAP) and a TIMS (Trekkers’ Information Management System) card, both of which fund conservation work and help authorities track trekkers on the route.
Has the Annapurna Circuit trekking disaster of 2014 changed safety rules?
Yes. Following the October 2014 storm that killed at least 43 people, Nepal introduced trekker registration checkpoints, passed area weather alerts, and mandatory guide requirements in restricted zones.
What is the survival rate for trekkers who experience severe altitude sickness?
With prompt recognition and immediate descent or evacuation, most trekkers recover fully from even severe AMS. Deaths typically occur when symptoms are ignored or descent is delayed.
How can I choose a safe trekking company for Annapurna?
Look for companies with licensed guides, acclimatization-focused itineraries, transparent emergency protocols, and an established safety track record, rather than the cheapest or fastest available schedule.
Is the Mardi Himal trek safer than the main Annapurna Circuit?
Mardi Himal is generally considered lower risk due to its shorter duration and lower maximum altitude, though it recorded one altitude sickness death this year, confirming that proper acclimatization still matters on this route.
What happened during the October 2014 Annapurna Circuit disaster?
A sudden storm dumped roughly 1.8 meters of snow on Thorong La Pass in 12 hours, killing at least 43 trekkers and triggering the largest helicopter rescue operation in Himalayan history at the time; more than 400 people were evacuated.
Can medication help prevent altitude sickness on the Annapurna trek?
Acetazolamide (Diamox) is commonly used as a preventive measure for AMS, but it should only be taken after consulting a doctor familiar with your medical history, and it is not a substitute for proper acclimatization pacing.
How does the Annapurna region’s safety compare to the Everest Base Camp route?
Both regions post altitude sickness deaths most years and carry broadly similar underlying risks. Everest Base Camp has a denser medical and rescue network in the Khumbu, while Annapurna relies on ACAP checkpoints and a seasonal aid post in Manang.
