Claimed to be the third highest motorable mountain pass in the world, Chang La Pass at an altitude of 5,360 meters above sea level is the main gateway to the Changthang Plateau. To approach the pass, one should have some good driving skills as it is steep. Especially during the summer when the snow melts and small streams cross the trails, it gets extremely difficult for the travellers to cross the pass. Even the doctors say that traveler shouldn't stay at the top for more than 20-25 minutes as it gets difficult to breathe. The pass is mainly used to reach the Pangong Lake, a popular tourist attraction, from Leh. Also, it is an important gateway for the Changthang Plateau situated in the Himalayas. Defence Research and Development Organisation, world's highest station, is functional in Chang La. Travellers should visit the temple close to the Chang La pass to tie the Tibetan flag for a happy journey ahead. Also, there's a canteen up there that serves good black coffee. The pass remain open for tourists only between April and October.
