After breakfast leave for Yumthang (11,800 ft.), the “Valley of flowers”.
Yumthang is a lush green valley with herds of Yak grazing around and surrounded by snow peaks on all sides where the tree line ends. You will be travelling across the Shingba Rhododendrom Sanctuary which has more than 120 species of Rhododendron trees and is also the home to the endemic Rhododendron Niveum, the State Tree of Sikkim.
In April / May / June the valley erupts in a riot of colours as Rhododendrons, Primulae and many other Alpine Flowers are in full bloom.
In the winter, Yumthang is sombre with snow all around, and the snow clad mountains add to the ethereal beauty of this place.
On the way back, you may visit the famous hot spring across the Lachung River, although it is mainly used for bathing purposes by the army personnel.
Return to Lachung for lunch. After lunch, visit Lachung Monastery, Cottage Industry and Waterfalls. All these are within walking distance and can be visited while taking a stroll through Lachung. Overnight stay will be at Lachung.
Visitors may also want to visit Yumesamdong/Zero Point. Zero point is close to Yumesamdong, contrary to popular belief that they are the same places. After reaching Yumesamdong, one needs to walk a little to reach Zero point. Officially one is not allowed to visit Yumesamdong/Zero Point.
