Lachung & Lachen (North Sikkim Circuit)

Highlights

Overview

Lachen and Lachung are twin Himalayan villages in North Sikkim that serve as the gateway to some of India's most extreme and breathtaking landscapes. Lachen, meaning "Big Pass," is the base for visiting the sacred Gurudongmar Lake, one of the highest lakes in the world at 17,800 ft. Lachung, meaning "Small Pass," sits amidst snow-capped peaks and serves as the entry point to the Yumthang Valley of Flowers and Zero Point. These regions recently reopened in March 2026 following infrastructure restoration from 2023 flood damage. The experience is defined by high-altitude plateaus, grazing yaks, ancient monasteries, and vibrant rhododendron blooms in spring. Due to their proximity to the Indo-China border, travel here is strictly regulated via permits and organized tours.
