After breakfast, proceed to Tsongmo Lake (12,210 ft) and Baba Mandir, a 40 km drive which takes 2.5 hrs. This lake is located very close to Nathu La Pass, which is the entry point to China termed as the “Silk Route” and remains frozen for most parts of the year. The lake is home to the Brahminy ducks and many migratory birds. Nearby is the sacred Baba Mandir, which is highly acknowledged for its spiritual worth. We can also visit the Nathu La Pass, which is the border between India and China. Later drive back to Gangtok. In the evening you are free for your own activities, followed by overnight stay at the hotel.
