About the Destination

Overview

Yumthang Valley is a high-altitude sanctuary situated at an elevation of 3,564 meters in North Sikkim. It sits near the tree line, surrounded by rugged Himalayan mountains. The valley floor features vast grazing pastures, pine forests, and the winding Lachung River. During the spring season, the integrated Shingba Rhododendron Sanctuary blooms with over 24 species of rhododendrons, covering the landscape in distinct shades of red, pink, and purple. Visitors typically explore the main valley floor on foot, walking along the riverbanks and observing the grazing yaks. A pedestrian bridge over the Lachung River leads to natural hot springs, housed in a small structural complex. The drive from Lachung to Yumthang takes about an hour and passes through dense forests and waterfalls. The terrain is rocky and the weather shifts rapidly, making it a rugged but accessible high-altitude environment.
