Bum La marks the approximate point where the 14th Dalai Lama entered India while seeking asylum in 1959.
The pass remains snow-covered for the majority of the year due to its extreme altitude of over 15,000 feet.
It is one of only five officially agreed-upon border meeting points between India and China.
The location is prone to rapid weather shifts, occasionally causing visibility to drop to zero within minutes.
The pass is situated in the Tawang district, which is home to the Galden Namgey Lhatse, one of the world's largest monasteries.
Bum La is a high-altitude mountain pass located at an elevation of approximately 15,200 feet on the border between India and China. It serves as one of the designated Border Personnel Meeting (BPM) points between the Indian Army and the People's Liberation Army. The pass is situated 37 kilometers from the town of Tawang in the Indian state of Arunachal Pradesh. Historically, the area was the route taken by the 14th Dalai Lama when he fled Tibet in 1959. Due to its strategic location, civilian access is strictly regulated and requires special permits obtained in Tawang. The surrounding terrain is marked by alpine lakes and rugged, barren mountain landscapes. Visitors can observe the Line of Actual Control and interact with the local border administration representatives. The area is subject to extreme weather conditions, including heavy snowfall and sub-zero temperatures throughout much of the year.
