Tsomgo (Changu) Lake

For Indian Nationals: A Protected Area Permit (PAP) is required. You must provide a valid government ID (Voter ID, Passport, or Driving License) and two passport-sized photos. Aadhar Cards are no longer accepted for this permit.

For Foreign Nationals: A Protected Area Permit (PAP) is required and must be arranged through a registered travel agency for groups of two or more. Solo foreign travellers are generally not permitted.

Permit Processing: Most permits are processed one day in advance through authorized tour operators in Gangtok.

Altitude Sickness: Since the lake is at 12,300 ft, travellers may experience shortness of breath or dizziness; carry portable oxygen cylinders if needed.

Weather Closures: Access can be restricted immediately during heavy snowfall or landslides; always check latest updates from Sikkim Tourism before heading out.

Medical Facility: Small first-aid stations are maintained by the Indian Army nearby; major facilities are back in Gangtok.

Emergency Contact: 112 (Statewide Emergency).

Layered Clothing: Even in summer, the wind chill at the lake is significant. Wear heavy woollens and waterproof jackets.

The "Head" of the Lake: The name "Tsomgo" comes from the Tibetan Tso (lake) and Mgo (head), literally meaning the "Source of the Lake".

Yak Photos: If you don't want a full ride, you can often pay a smaller fee (approx. ₹50) just to sit on a decorated yak for a photo.

Nathula Combo: Most tourists combine Tsomgo Lake with visits to Baba Mandir and Nathula Pass (only for Indians) on the same day trip
