Catch an early morning flight from Kolkata Netaji Subhas Chandra Bose International Airport to Bagdogra Airport. The flight takes approximately 1 hour and 35 minutes.
Head to Tsomgo Lake (approx. 40 km from Gangtok), a glacial lake often surrounded by snow, especially from December to March. April could have lingering snow on peaks - enjoy the cold mountain air and panoramic views. You can also explore nearby snowfields and try yak rides.
