Tsomoriri or Lake Moriri lies in the Changthang area in Jammu and Kashmir. The lake is at an altitude of 4,595 m (15,075 ft); it is the largest of the high altitude lakes in the Trans-Himalayan region.The lake sits between Ladakh, India to the North, Tibet to the east, and Zanskar in the west.
The lake is fed by springs and snow-melt from mountains on the Changthang plateau. The lake was a source of salt for local people until 1959. this is reflected in the lake's name; Tsokar means salty lake in local language.
The lake is located to the southeast of Leh in eastern Ladakh, Jammu & Kashmir, at a road distance of 240 kilometres (150 mi). The road is in a good condition for the most part. Accessibility to the lake is limited to summer season only. One can also reach Tsomoriri directly from the Pangong Tso via the remote Changtang region. This is considered to be one of the most beautiful drives in the entire Ladakh region.
The Korzok Monastery, on the western bank of the lake is 400 years old and attracts tourists and Buddhist pilgrims. Tourism during May – September attracts large number of foreign and local tourists even though tented accommodation is the facility available, apart from a small PWD guest house close to the Lake. Just before reaching Tsomoriri Lake, one could see the small lake which is known as Lake of Joy.
