The Yambong Singalila Trek spans the borders of West Bengal, Sikkim and Nepal. It passes through verdant valleys, forests and glacial lakes in the Singalila mountain range. The trek promotes community involvement and sustainable tourism by providing an alternative livelihood for local yak herders and villagers. It traverses from Nambu to Yuksom over 13 days, climbing through forests and meadows with views of the Khangchendzonga range, and opportunities to explore the area's biodiversity and cultural sites.
