Assam's 6th National Park: The Triumph of Bodoland Conservation
Formally notified on World Environment Day, June 5, 2021, Raimona National Park is the 6th National Park of Assam and a shining jewel in the conservation portfolio of the Bodoland Territorial Region (BTR). Spanning a magnificent territory of 422 square kilometers within the Gossaigaon subdivision of Kokrajhar district, the park encompasses the northern portions of the historic Ripu Reserve Forest. The declaration of Raimona represented the culmination of decades of grassroots ecological stewardship led by indigenous Bodo communities, local youth conservation volunteers, and forest authorities.
Geographically, Raimona is bordered by the pristine Sankosh River along its western boundary (which forms the interstate boundary with West Bengal and the Buxa Tiger Reserve), the Saralbhanga River to the east, and the international frontier of Bhutan to the north. Together with the neighboring Phibsoo Wildlife Sanctuary and Royal Manas National Park in southern Bhutan, Raimona forms an expansive, unfenced trans-boundary biological landscape exceeding 1,200 square kilometers.
The terrain of Raimona is a lush, undulating expanse of semi-evergreen and moist deciduous forests dominated by tall sal (Shorea robusta), gamari, and titasopa trees, interspersed with natural grassland savannahs and seasonal riverbeds (khols) that tumble down from the Bhutanese hills.
Assam's 6th National Park & Trans-Boundary Corridors
Declared as Assam's 6th National Park on World Environment Day (June 5, 2021), Raimona covers 422 square kilometers of the historic Ripu Reserve Forest. The park forms a vital contiguous trans-boundary conservation landscape with the Royal Manas National Park and Phibsoo Wildlife Sanctuary of Bhutan, creating an unbroken international wildlife corridor for migrating Asian elephants, tigers, and cloud leopards.
The Golden Langur Realm: Conserving a Global Primate Icon
Raimona National Park holds immense global conservation significance as the prime ecological stronghold of the endangered Gee's Golden Langur (Trachypithecus geei). Endemic exclusively to a narrow geographic strip between the Sankosh River on the west and the Manas River on the east, the golden langur is celebrated as one of the most visually stunning primates on earth, sporting an ethereal cream-golden coat that turns into a rich honey-orange hue during the winter months.
The dense sal forest canopies of the Ripu belt provide the specialized fruiting trees and tender leaf shoots essential for the survival of golden langur family troops. Visitors on morning nature trails can regularly spot these graceful primates leaping across the forest canopy, their long tails trailing behind them as they vocalize with gentle grunts and alert calls.
The creation of Raimona National Park provided long-awaited statutory legal protection to these fragmented primate populations, halting habitat fragmentation and creating contiguous canopy bridges that allow troops to move safely across traditional foraging ranges.
Trans-Boundary Mega-Herbivores & Apex Predators
Raimona serves as an indispensable international migratory corridor for wild Asian elephants (Elephas maximus). For centuries, large breeding herds have migrated seasonally between the lowland plains of Assam, the foothills of West Bengal, and the high forested valleys of Bhutan. Protecting this contiguous forest corridor has significantly reduced human-elephant conflict across the agricultural borderlands of Kokrajhar.
The park also supports a formidable assemblage of apex predators and large mammals. Camera-trap surveys conducted by wildlife biologists have documented the presence of Royal Bengal Tigers, Indian Leopards, Clouded Leopards (Neofelis nebulosa), Asian Golden Cats, and Dholes (Asiatic wild dogs).
Herbivores thrive throughout the varied forest strata, with healthy populations of gaur (Indian bison), sambar deer, barking deer, hog deer, and wild boars. The pristine riverbanks along the Sankosh and Saralbhanga rivers are home to smooth-coated otters, freshwater turtles, and rare hill-stream fish.
International Frontier Buffer & River Currents
Raimona borders Bhutan along the north and West Bengal's Buxa Tiger Reserve to the west. River streams like the Sankosh and Saralbhanga can experience sudden monsoon flash floods. Stay on authorized forest department safari routes, carry valid photo identification for forest checkpoint verification, and avoid swimming in deep river channels.
Avian Diversity & The Butterfly Capital
With over 260 recorded bird species, Raimona is rapidly gaining fame as an undiscovered birdwatching paradise in Western Assam. The park's diverse canopy layers provide niches for four species of majestic hornbills: the Great Pied Hornbill, the Wreathed Hornbill, the Oriental Pied Hornbill, and the Rufous-necked Hornbill.
Other prized avian specialties include the endangered White-bellied Heron, the Ibisbill (which winters on pebbled riverbanks), the Blyth's Kingfisher, the Blue-naped Pitta, the Pale-headed Woodpecker, and the Sultan Tit. In the winter season, the forest is filled with the melodious songs of diverse thrushes, flycatchers, and babblers.
Raimona is equally celebrated for its staggering entomological diversity, harboring over 150 species of brilliant butterflies and moths. Along sunny riverbank sands, visitors can witness the enchanting spectacle of 'mud-puddling', where hundreds of colorful swallowtails, jezebels, and swordtails congregate in dense, fluttering carpets to absorb essential mineral salts from the moist earth.
Travel Logistics, Community Eco-Tourism & Visitor Tips
Raimona National Park is located approximately 55 kilometers northwest of Kokrajhar town and 25 kilometers from Gossaigaon railway station. Paved roads connect Kokrajhar and Gossaigaon to the central forest range office at Kachugaon and the primary safari entry gate at Raimona. The drive from Guwahati takes roughly 4 to 4.5 hours via National Highway 27.
Eco-tourism in Raimona is managed with deep community involvement through the Bodoland Territorial Council and local Eco-Development Committees (EDCs). Guided 4x4 open gypsy safaris and authorized nature walking trails allow travelers to explore the wilderness under the supervision of trained local youth guides and armed forest guards.
Accommodations are available at community-run eco-camps and traditional Bodo tribal homestays in nearby villages. Staying in a local homestay provides a wonderful cultural immersion: enjoy authentic Bodo culinary specialties like pork cooked with bamboo shoots (Ohm Bedor), herbal chicken dishes, and fresh river fish, accompanied by warm tribal hospitality. Combine Raimona with Manas National Park (120 km east) for an extraordinary dual-park expedition across the Bodoland frontier.
