Tilicho Lake is a lake located in the Manang district of Nepal, at 55 km areal distance from Pokhara. It is situated at an altitude of 4,919 metres (16,138 ft) in the Annapurna range of the Himalayas and is known as the highest lake for its size in the world, even though there are lakes at higher altitude even in Nepal. Another source lists the altitude of Lake Tilicho as being 4,949 metres (16,237 ft).


According to the Nepali Department of Hydrology & Meteorology (2003), no aquatic organism has been recorded in the lake.



Mountain lakes are known to geographers as tarns if they are caused by glacial activity. Tarns are found mostly in the upper reaches of the Himalaya, above 5,500 metres (18,000 ft).


Tilicho Lake is the destination of one of the most popular side hikes of the Annapurna Circuit trek. The hike takes additional 3–4 days. No camping is required, as new lodges have been built between Manang and the lake. The final approach to the lake is done in a day hike from the lodge at Tilicho Base Camp.
