Day Trip from Gangtok to Tsomgo (Tsomgo/Changu) Lake: Drive, Views & High-Altitude Insight
Select participants and date
You arrive before sunrise and the hill road already tastes of cold: diesel, pine resin and the thin metallic air that comes with climbing. The van hums as it peels away from Gangtok, and in 25 miles the town’s soft pastels give way to a sharper geometry of snow cornices, prayer flags and jagged ridgelines. Tsomgo—also called Changu Lake—appears like a high-mountain eye: a glassy oval ringed by snow that can change color with the light and the mood of the sky.

Dress in windproof layers
Temperatures drop fast at the lake; bring an insulated jacket and a windproof shell even if Gangtok is mild.

Monsoon and winter storms can close roads—confirm with your operator and allow flexibility in your schedule.
