Day trips In Gangtok Tour Package- Tsongo(Changu) Lake, Baba Mandir & Nathula Pass
Most popular and probably the best day tour from Gangtok is a trip to Tsomgo (Changu) Lake - Glacial lake 35kms from Gantok and at an altitude of about 12,310 ft. This trip also covers the Baba Mandir. You can additionally cover Nathula Pass which is further up and about 52kms from Gangtok and see the Indo Chinese border and the Chumbi valley through which the old Silk Route (i.e. the trade route between India and Tibet) passes.
Tsomgo lake and Baba Mandir combination takes about 5-6 hours round trip (including the time it takes to see the places). With Nathula it becomes a full day trip.
