Yumthang Valley, the Valley of Flowers
Yumthang Valley is situated in North Sikkim and is famous for its picturesque beauty. The valley is located north of the state capital, Gangtok.

Yumthang is located on a flat valley and is near the tree line; surrounding mountains seem to touch the heavens. The route to Yumthang from Lachung adjoins the Singba Forest Reserve.
Tourists require an inner line permit to travel to North Sikkim, which can be obtained with the help of a travel agent. During the season, the tourism department organizes package tours to Yumthang.
Note: This area is landslide-prone from June to September.

Best Time to Visit: March to June (spring/summer) for blooming rhododendrons, and October to December (early winter) for snow. A typical tour from Gangtok to Yumthang takes 2 days and 1 night.
