Singhalila National Park lies in the extreme north-west of Darjeeling district. It is bounded by Rabonglia Khola in Sikkim in the north and Nepal in the west and south. The Singhalila ridge rises from Maneybhanjyang and links Tonglu, Sandakphu, and Phalut in Darjeeling district, continues higher into Singhalila National Park. It then joins the Khangchendzonga Biosphere Reserve in Sikkim. The National Park supports lower temperate forest, evergreen broadleaf forests, upper temperate Tsuga dumosa forest, sub-alpine conifer forest, and bamboo.
