The Comprehensive Guide to Nameri National Park
Located in the foothills of the Eastern Himalayas in Sonitpur district along the border of Assam and Arunachal Pradesh, Nameri National Park is one of the most pristine and unique protected wilderness areas in India. Bordered by the crystal-clear Jia Bhoroli (Kameng) River, it spans dense semi-evergreen and moist deciduous forests that harbor over 370 bird species and rich mammal populations.
The Unique Walking Safari Experience (November to April)
Unlike almost all other Indian tiger reserves where visitors are strictly confined inside motorized safari jeeps, Nameri is celebrated for its guided walking forest safaris:
- The River Crossing: Safaris begin at the Potasali forest range post, where visitors board small wooden country dinghies to cross the wide, sparkling Jia Bhoroli River into the core forest.
- Armed Forest Escorts: Under strict wildlife regulations, every trekking group (maximum 4-6 persons) is escorted by an armed forest department guard and an expert local naturalist.
- On-Foot Tracking: Walk quietly along 5-km to 10-km trails through primary rainforest, tracking Asian Elephants, Capped Langurs, Wild Dogs (Dholes), and occasional leopards while listening to the calls of the forest.
Jia Bhoroli River Rafting & Golden Mahseer Angling
The Jia Bhoroli River is the lifeblood of Nameri. From November through April, the river runs with transparent emerald clarity.
- Scenic Inflatable Rafting: A 13-km gentle float takes visitors down scenic river rapids with panoramic views of the blue Arunachal Himalayan ridges, offering unmatched vantage points for spotting Kingfishers, Pallas's Fish Eagles, and the rare Ibisbill foraging on pebble shingle bars.
- Golden Mahseer Conservation: Nameri is world-renowned for sport angling for the mighty Golden Mahseer (Tor putitora). Operated strictly on a catch-and-release conservation model with single barbless hooks, angling permits are regulated by the forest department and the Assam Anglers Association.
Birding Capital: The White-Winged Wood Duck
Nameri is one of the last remaining global strongholds for the critically endangered White-winged Wood Duck (Asarcornis scutulata), the State Bird of Assam. Spotting this secretive duck in secluded forest waterbodies (pukhuris), alongside Great Pied Hornbills, Rufous-necked Hornbills, and Black Storks, makes Nameri a bucket-list destination for ornithologists.
