Lachung (Tibetan: Small Pass) is a small hill town at an elevation of 9600 ft, very close of the Indo-Tibetan Border. It is located near the confluence of the rivers Lachen and Lachung, tributaries of the Teesta river. The town serves as pitstop for travellers going to the Yumthang valley and is a very picturesque place in itself.

Yumthang is located in the Shingba Rhododendron Sanctuary and is popularly known as Sikkim’s Valley of Flowers. It lies on the way from Lachung to Zero Point and is a “must get down from the car and spend 2 hours” kind of place where you will find 24 varieties of Rhododendron flowers, many Yaks, prayer flags,  a mountain stream and happiness! Please be mindful of the fragile ecology.

Yume Samdong lies around 26 km after Yumthang Valley and takes about 3 hours to reach from Lachung. The place is often referred to as ‘Zero Point’ as there is no motor-able road beyond this place where tourists are allowed. This mountain top is flocked by tourists in the peak season who come to enjoy the snow. It can get chaotic at times!
