Gangtok, the capital of Sikkim since the mid-19th century, sprawls down the west side of a long ridge flanking the Ranipul river. The scenery from this hill town is spectacular and there are excellent views of the entire Kanchenjunga Range from many points within the city. North of Gangtok is the Enchey Gompa and the telecommunication tower. The palace of the former Chogyal, or ruler of Sikkim, and the impressive Royal Chapel are lower down along the ridge. Then there is the Namgyal Institute of Tibetology, an Orchid Sanctuary and a large chorten (Tibetan stupa) with an adjoining gompa.

Gangtok is a very popular hill station resort with many fine hotels filled with visitors from all over the country.
