Yumthang valley, a plateau surrounded by beautiful snow peaks, is a delight to witness. Beware of the rough, treacherous roads that lead to this place. It is popularly known as 'Valley of Flowers' and is home to the Shingba Rhododendron Sanctuary that has over twenty-four species of rhododendrons. The flowering season is from late February to mid June, when countless flowers bloom to carpet the valley in multicolored hues. There is also a hot spring in the valley.
