Gangtok to Tsomgo Lake: Permits, Route and Timing

The name means “source of the water” in the Bhutia language. The lake is regarded as sacred, and a tradition holds that Buddhist monks read the colour of its water to forecast the future.

Greendale Residence is a hotel in Gangtok, the city used as the starting point for this excursion.

The drive from Gangtok takes about two hours, and the road to Nathu La passes Tsomgo Lake. You can travel by taxi, jeep or shared taxi after obtaining a permit. The route toward Nathu La Pass from Gangtok also goes by the lake.

You need a protected-area permit to visit Tsomgo Lake. The Sikkim Tourism Department says that, for domestic visitors, permits are issued through registered travel agencies and by the Police Check Post. Confirm the application process with a registered agency before arranging transport.

Foreign visitors must travel in a group of two or more and apply through a registered travel agency. Their visitor permit is issued by the Tourism & Civil Aviation Department, while the vehicle permit is issued by the Police Check Post. Passes for foreign visitors are issued for one day only.

Foreign applicants need a passport, Indian visa and two passport-size photographs, among other documents. Citizens of Pakistan, Afghanistan or China, including Hong Kong and Macau, need prior approval from India’s Ministry of Home Affairs before applying for a Restricted Area Permit. Motorbikes entering protected-area-permit areas must have an engine capacity of 150 cc or higher.

Tsomgo Lake sits at high altitude. Be aware of the possibility of altitude sickness. Check Gangtok’s seasonal weather patterns as you plan your wider trip.

Stalls at the lake serve snacks and beverages, and snowboots and gumboots can be hired there. Facilities and activities include parking, souvenir shops, yak and mule rides, ropeway rides and ethnic-dress photo opportunities. Movement around the lake is limited; you may walk or cycle, while vehicles using the road around the lake need a permit.

The Gangtok District government gives opening hours as 10:00 am to 4:00 pm throughout the week and a journey time of about two hours from Gangtok. These arrangements and access requirements can change, so check the official site before you go.

If you are driving, park only in designated parking yards or identified places at Tsomgo; roadside parking is not allowed. For other stops in town, the Gangtok itinerary from MG Marg to the viewpoints covers a separate city route. Confirm your permit and transport arrangements before leaving Gangtok.
