Road trip guide: Conquering the infamous Tangkar La
Tangkar La is an international high mountain pass located on the border of India and China.
The pass links North Sikkim (a district of the Indian state of Sikkim) and Yadong County (in the Tibet region of China, part of its Shigatse Prefecture). There are 2 separates roads to the summit, but the road does not cross the border.
Set high on the scenic Yumthang Valley, on the Indian side, the road to the summit is totally unpaved. A 4x4 vehicle is required. It tops out at 4.439m (14,563ft) above the sea level. It’s a military road, and the access is closed to civilians.
