The Sankosh River divides the Dooars into western and eastern parts, distributed through Sikkim and West Bengal. Known as the gateway to India from Bhutan, the Dooars are a natural diversity hotspot. Nature lovers and thrill seekers can go whitewater rafting on the Teesta River. There are also some exciting treks and forest safaris available here. The area is also a birder's paradise, with various avian species. Deeply rooted in tea, tourism, and timber, the region is served by a network of motorable roads cutting through the dense forests. The valley has many national parks and wildlife sanctuaries, such as Buxa, Jaldapara, Chapramari, Gorumara, and Manas. The region abounds as an ecotourism and birding hub, separated into three parts—eastern Dooars, Central Dooars and Western Dooars. The Buxa National Park in Eastern Dooars offers a great collection of orchids and medicinal plants, while Jaldapara in Central Dooars is home to primaeval forests interspersed with sleepy settlements. The main attraction here is the one-horned rhinoceros. A preferred destination for wilderness explorers, a safari through the emerald-green forests of Dooars is a great way to experience nature at its best.
