Sarchu (also known as Sir Bhum Chun) is a major halt point with tented accommodation in the Himalayas on the Leh-Manali Highway, on the boundary between Himachal Pradesh and Ladakh (Jammu and Kashmir) in India. It is situated between Baralacha La to the south and Lachulung La to the north, at an altitude of 4,290 m (14,070 ft). It is a disputed territory between the states of Himachal Pradesh and Jammu and Kashmir. The journey along the Manali-Leh highway at high altitude and variable road conditions, normally takes two days, so travellers and tourists use this spot as an overnight stop. An Indian army camp is sited nearby on the banks of the Tsarap Chu river. The highway and thus the camp are closed during the winter, when snow blocks the high passes along the road. This spot can also be used as a start point for the difficult trek into the Zanskar region of Ladakh.
