Green Lake Trek
One of India's most exclusive and restricted treks, Green Lake takes you to 5100m at the foot of Kanchenjunga's north face in a zone that requires special permits from the Himalayan Mountaineering Institute. The 8-day expedition passes through rhododendron tunnels, yak pastures, and glacial moraines in an area that sees fewer than 200 trekkers per year. Green Lake itself sits in a glacial bowl with Kanchenjunga towering above.
