Overview
The Yumthang Valley, in North Sikkim, lies at about 3,564 m on the Lachung river and is known as the Valley of Flowers. In spring, the slopes of the Shingba Rhododendron Sanctuary are covered in blossom, and the surrounding peaks are streaked with snow.
The base for the valley is the village of Lachung, about 25 km away, with simple hotels and homestays. Hot springs near the valley are a draw, and the road continues to Zero Point, at 4,700 m or higher, where snow lies for much of the year. Permits are needed to visit North Sikkim, and the region is near a border area, so check current rules.
