The Comprehensive Guide to Manas National Park
Nestled against the gentle foothills of the Bhutan Himalayas in western Assam, Manas National Park is a UNESCO World Heritage Site, Project Tiger Reserve, Biosphere Reserve, and Elephant Reserve. Contiguous with Royal Manas National Park in Bhutan, this protected wilderness harbors iconic and critically endangered species found nowhere else on earth.
Safari Ranges & The Winter Season (November to April)
Manas operates across three distinct administrative ranges, all of which are open exclusively from November 1 to April 30:
- Bansbari (Central Range): The primary tourism hub leading to the historic Mathanguri forest lodge on the Bhutan border. Famous for dense elephant herds, Golden Langurs in the sub-Himalayan canopy, and river rafting.
- Bhuyanpara (Eastern Range): Dominated by expansive alluvial grasslands and wetlands, this range offers the highest density of Greater One-horned Rhinoceroses, Wild Water Buffaloes, and the world's premier habitat for the critically endangered Bengal Florican and Pygmy Hog.
- Panbari (Western Range): Dense semi-evergreen forest adjoining the foothills, exceptionally rich in birdlife, Hornbills, and Capped Langurs.
Unique River Rafting on the Manas River
Unlike most Indian tiger reserves where activities are confined strictly to jeep tracks, Manas offers gentle, scenic inflatable boat rafting on the crystal-clear Manas River. Starting from the inspection bungalow at Mathanguri, the 3-hour float drifts silently along the international border between India and Bhutan, providing unique water-level vantage points of elephants, deer, and riverine birds like the rare Ibisbill and Mergansers.
Monsoon Closure & Conservation (May to October)
From May through October, massive runoff from the Bhutan Himalayas rushes through the Manas, Beki, and Hakua river channels, submerging low-lying tracks and turning forest roads into impassable mud. The park strictly closes to ensure animal breeding safety and prevent disruption to wildlife nurseries.
