The Bum La Pass is located about 37 km away from Tawang in Arunachal Pradesh, at the Indo-China border above 15,200 ft above sea level. An old traders road went from Tawang via Milakatong La Pass (La in Tibetan is to Bum La Pass and finally to Tsona Dzong in Tibet province of China. The road to Bum La is also a historical route, the People’s Liberation Army of China invaded India during the 1962 Sino-Indian War. Here in Bum La Pass one of the fiercest battle took place in the 1962 Sino-Indian War. In 2006, Bumla pass was re-opened to traders for the first time in 44 years. Traders from both sides of the pass were permitted to enter each other’s territories, in addition to postal workers from each country. It is often covered with heavy snow throughout the year. It is one of the most off-beat passes in the world.
This is a really beautiful place. This location is off the beaten track for those who love roaming in the wilderness. It is a fantastic place for a picnic of a lifetime if you move out of Tawang by around 7am and carry in everything yourself.
Visit by civilian tourist of India is permissible with permission from the Indian Army. The track is very treacherous, only SUVs advisable, and that too only on clear weather day with no snowfall or rainfall.
