About Zero Point
Zero Point, officially called Yumsedong, is the last accessible point on the Yumthang Valley road at 4,665m — the northernmost point tourists are permitted to reach in Lachung. Beyond this is the restricted military zone leading to the China border. The landscape is completely above the tree line: bare rock, ice sheets, a frozen river and silence. The Teesta originates from glaciers visible from here. The drive from Lachung (48 km) passes through Yumthang Valley before the road climbs steeply through switchbacks to the snowfields. Most visitors see snow here even in June when the lower valley is green.
Why go to Zero Point
Above the treeline at 4,665m
At Zero Point the world becomes rock, ice and sky. The Teesta source glaciers are visible above. On clear days, the peaks on the Tibet border loom very close.
Snow almost guaranteed year-round
Even in summer (June), permanent snowfields surround Zero Point. For many visitors from the plains, this is their first experience of touching snow and standing in a snowfield.
