Visit Yumthang Valley is a day excursion from Lachung, which is an attraction for tourist visiting this region. The colorful Singba Rhododendron Sanctuary bloom between April to June. The soaring snow-capped peaks and herds of wandering yaks make this a Himalayan paradise. The valley is also known for its Hot spring. Although the water is quite dirty, many locals from the area visit to get themselves soaked & cured as believed. Overnight at Hotel.
