Yumthang valley is about 25kms from Lachung located at an altitude of 11,800ft and takes about 1.5 hours of drive. The name Yumthang Valley means 'Valley of Flowers'. So you know what to expect. But the name would have been more appropriate if it said 'Valley of Rhododendrons'. Because here as the tree line ends and the vast stretch of flowering valley exposes a dense bed of rhododendron flowers for miles and in many different colors like purple, blue, red, pink etc.
