How Difficult is Annapurna Circuit Trek?

The Annapurna Circuit Trek is considered a Moderate-to-challenging, high-altitude trek, and is recognised as one of the hard trek and requires some level of strength and endurance. The trek can be done in 10-16 days of the itinerary. Due to the road accessibility, you can quickly skip the initial days and reach Dharapani and start the trek from there and cross the Challenging Thorong La Pass 5416 M / 17,769 Ft. The Trek requires 6–8 hours daily, reaching a maximum altitude of Thorong La Pass. Key difficulty factors of the Annapurna circuit treks are High altitude, Thorong La Pass, terrain & remoteness, physical demands and potential altitude sickness.

The Ultimate Challenge: Thorong La Pass


  • Maximum Altitude: 5,416 meters (17,769 feet) Thorong La Pass
  • Walking Duration: 6-8 hours daily
  • Trek Days: 10-16 days
  • Terrain: Steep uphill, potentially snow-covered pass, and a long, knee-straining descent to Muktinath.

1. High Altitude and AMS (Acute Mountain Sickness):

The most challenging issue of the Annapurna Circuit Trek is the altitude. The trek begins at the low elevation of Dharapani, 1,960 meters (6,430 feet), and gains elevations of 300m to 600m each day before the summit of the Thorong La, 5,416 meters (17,769 feet), which is a very significant altitude. Between these two points, very few trekkers may experience altitude sickness above 3000 meters because of an insufficient level of oxygen. In this trek after Upper Pisang, the oxygen levels drop significantly. So there is some chance of getting the Altitude Mountain Sickness.



Why AMS May happens here

  • The Danger Zone:
    The trails from Manang, 3,540 meters (11,614 feet) up over Thorong La Pass, Thorong La, 5,416 meters (17,769 feet), is a risky zone in terms of AMS because of the lower oxygen in this area.

  • Rushing quickly
    This is another reason that many trekkers may face the AMS because the body needs some time to acclimate properly



→ What are the things that can overcome AMS?

  • In our plan, we have set up an acclimatisation day in Manag at 3,540 meters (11,614 feet). Also on this day, we will take you to the Ice Lake 4,620 meters (15,157 feet) to see the stunning scenery and be acllimitize. In mountains, hike high, sleeping low principles work very much, and this is very effective against the AMS and increases the body’s resistance against the AMS.
  • Slow and steady, a peace trek can help significantly to overcome the issue.
  • Hydrate the body enough by drinking enough water, 2-3 liters water each day.
  • Eat a healthy, carb-rich diet during the trek, and avoid smoking and drinking alcohol during the trek
  • Nepali people believe that eating the garlic soup helps against the AMS.

2. The Thorong La Pass, 5106 meters, is a challenge:

The Thorong La Pass 5,416 meters (17,769 feet) is a challenging altitude to cross, and there is a longer distance to cover on that day. Due to thin oxygen levels, slippery moraine trails, adverse weather conditions and many other things, the Thorong La Pass is challenging, and most of the trekkers may struggle to cross because this day requires endurance and stamina.



  • The Uphill climbing in the early morning
    The ascent to Thorong La Pass begins at around 3:00 or 4:00 AM from Thorong Phedi 4,450 meters (14,596 feet) or High Camp 4,925 meters (16,158 feet) to avoid the afternoon winds at the summit. It is very cold to start the hike that early, and trekkers must have a headlamp to find the trails.


  • The Knee-Breaker windy Descent
    After the Thorong La pass, the descent is very tough as well because it is a steep descent down with multiple icy trails and continuous descents, which makes the knees and legs hurt. The total trekking hours may last about 7-10 hours.


→ What are the things that can help to Thorong la pass?

  • Carry enough water and snacks for the day, not in a rucksacks put on your day bags.
  • Slow and steady, a pace makes the accents and descents easy.
  • Having trekking poles, crampons, and gaiters makes the hike easier.
  • Hydrate the body enough by drinking enough water, 2-3 liters water each day.


3. Physical Demands:

The Annapurna Circuit is a physically demanding trek (10-14 days). The trek covers approximately 131 kilometres (81 miles) to 230 km (145 miles), with daily treks of 15–20 km. The routes have ascents and descents, mostly. Trekkers are required to trek (5-9 hours) each day. Some days are shorter, but the average is 6-7 hours for multi-day hiking, which makes the trekkers fatigued and exhausted, so high endurance is required



4. Terrain & Remoteness:

The Annapurna Circuit has incredibly diverse terrain, starting from lush, subtropical river valleys and terraced farms to barren, windswept high-altitude deserts resembling the Tibetan Plateau. Some parts of the trails are quite tough to walk due to the tough geography and geological risks as well.



5. Weather and temperature:

Unpredictable weather is another factor that poses difficulty. In recent years, due to global warming, even in the Spring and Autumn seasons, the weather changes very quickly and very unpredictably and may be adverse to trekking. These things make it more strenuous, especially in high-altitude areas. Normally, the spring and Autumn are the best two seasons for the trek, but there is no guarantee of the weather being stable, which can always make the temperature low and high, and the trek becomes harder. Spring and autumn are best, while winter brings heavy snow, and the monsoon brings rain/landslides



  • Quick Temperature Change
    Temperatures at the Thorong La Pass can plummet to -15°C to -20°C before dawn. Not only the pass, even in a lower area when the sun goes off, the temperatures quickly hit negative.


  • Snowfalls may happen at any moment
    During the Annapurna circuit trek, snowfalls may happen at any moment and at any time. Once the weather gets bad, snowfall is highly likely to happen on these routes.


  • High intensity winds
    Every day at Thorong La Pass after 9 AM or 10 AM, high winds start to flow, and that makes the trek difficult because the winds are very cold, so it is always good to cross the Thorong La Pass before the winds break out.


6. Duration of the Trek

The duration of the trek is another factor that makes the trek difficult. The short Annapurna Circuit Trek and the Annapurna Circuit Trek 10 days are tougher than the Classical Annapurna Circuit Trek because in a very few days you have to gain the significant level of the altitude.



→ Season and character

  • Spring & Autumn: The Spring and Autumn is best time to visit Nepal and trek, the weather is generally stable, but the pass can still have deep snow in March or early April. Also, the last week of November can be very cold and snow on the Thorong la pass.
  • Winter:Crossing the Thorong La Pass in winter is extremely tough, and often trails remain blocked due to heavy snow and temperatures dropping below -20°C or more

2026 Trail Conditions:

The road has been almost up to Khangsar on the way to Tilicho. The trek in the lower parts may be tough if there is a bit of traffic on the road, but there are NATT Trekking trails, and by using the NATT, you can avoid the dusty roads and enjoy the beauty of the trek. In some area the road is unavoidable but wherever is possible you can avoid the road and our Annapurna Circuit Trek is itinerary is designed like that ways.
