This is a hard trek. It’s the full Annapurna Circuit plus a three-day side trip to Tilicho Lake, with many days at high altitude and two very high days.
The hard parts
- The Tilicho trail. Between Shree Kharka and Tilicho Base Camp, the path crosses steep scree slopes with rockfall risk. Your guide checks conditions before you go.
- The lake day. About 790 m of climbing from Tilicho Base Camp (4,130 m) to Tilicho Lake (4,919 m), then back down to Shree Kharka.
- Thorong La. About 966 m of climbing from Thorong Phedi (4,450 m) to the pass at 5,416 m, starting before dawn, then a long descent to Muktinath.
Altitude
You sleep above 3,000 m on at least nine nights, with a rest day in Manang. The Tilicho detour also gives you extra time high up before Thorong La. Anyone can get altitude sickness: if you feel unwell, tell your guide and don’t go higher.
Who it suits
Fit, experienced walkers with about two weeks, ideally with a previous trek at altitude. If you’d rather skip the lake, see our Annapurna Circuit trek.
