Raimona National Park
Assam's sixth national park, a vital conservation corridor in the Bodoland Territorial Region.

A flash of gold in the canopy, a long tail draping like a question mark—the first glimpse of a golden langur is an unforgettable moment. This is the realm of Trachypithecus geei, the primate that serves as the mascot for Raimona National Park. The air here is thick with the scent of damp earth and foliage, a constant soundtrack of insect calls punctuated by the melodies of unseen birds. Bounded by the mighty Sankosh River to the west and the Saralbhanga River to the east, this forest feels ancient and alive, a testament to conservation efforts in a region healing from past conflicts.
History & Context
Declared a national park on June 5, 2021, World Environment Day, Raimona is the sixth and newest national park in Assam. Its 422 sq km area falls entirely within the Kokrajhar district of the Bodoland Territorial Region (BTR). The park's creation was a landmark step, fulfilling a long-standing demand from local conservation groups and the Bodoland administration. Historically, this area was part of the Ripu Reserve Forest, a large, contiguous patch of woodland. Its upgradation to a national park grants it the highest level of legal protection under the Wildlife (Protection) Act, 1972, crucial for safeguarding its vulnerable species and pristine habitats.
More importantly, Raimona is a critical piece in a much larger puzzle. It forms a contiguous forest landscape with Buxa Tiger Reserve in West Bengal to its west and the Phipsoo Wildlife Sanctuary in Bhutan to its north, creating a vast, 2,400 sq km transboundary conservation area. This unbroken corridor is vital for the movement of large, wide-ranging mammals, particularly Asian elephants.
What Makes It Distinctive
The park's undisputed star is the golden langur, a primate found only in a small region of western Assam and the adjoining foothills of Bhutan. Raimona protects one of the last viable populations of this endangered species. The park is also a designated Elephant Reserve, forming part of the Chirang-Ripu Elephant Reserve. Herds of Asian elephants migrate seasonally between Assam and Bhutan through these forests.
Beyond these flagship species, the biodiversity is immense. It's a potential habitat for tigers, clouded leopards, wild buffalo, and a host of deer species. The park is also a butterfly hotspot, with initial surveys indicating the presence of more than 150 species. The forest types range from semi-evergreen and moist deciduous to riverine grasslands, creating a mosaic of habitats that support this rich fauna.
Best Time to Visit
The ideal time to visit is during the dry winter and spring months, from October to April. During this period, the weather is pleasant and cool, humidity is low, and the chances of spotting wildlife increase as animals congregate near water sources and the vegetation is less dense.
- October to February: Cool and dry days make for comfortable safaris. This is peak birding season.
- March to April: Temperatures rise, but this is an excellent time for mammal sightings as they are often seen near rivers and waterholes.
- May to September: The monsoon season. Heavy rains make the forest tracks inaccessible and the park is generally closed to tourists. The forest is at its most lush, but travel is impractical.
How to Reach
- By Air: The nearest major airport is Lokpriya Gopinath Bordoloi International Airport (LGBI) in Guwahati, approximately 215 km away (a 4-5 hour drive). The smaller Rupsi Airport (RUP) near Dhubri is closer at about 80 km, but has limited flight connectivity.
- By Rail: The nearest major railway station is Kokrajhar (KOJ), about 70 km from the park's central areas. Fakiragram Junction (FKM) is another option. From the station, you can hire a taxi to reach the park entry points.
- By Road: Raimona is accessible from Guwahati via NH-27. The drive to Kokrajhar town takes about 4-5 hours. From Kokrajhar, park entry points like Kachugaon are a further drive. It is best to hire a dedicated vehicle from Guwahati or Kokrajhar.
Permits & Entry
Indian citizens do not require an Inner Line Permit (ILP) to visit Assam. Foreign nationals also do not require a Protected Area Permit (PAP) for Assam.
For park entry fees, safari charges, and timings: Information is not officially published or may change. Visitors are advised to confirm locally before travelling. Safaris are typically organized by the Forest Department at park gates like Kachugaon and it's recommended to make arrangements in advance.
Nearby Attractions

- Chakrasila Wildlife Sanctuary: Located near Kokrajhar, this is another prime habitat for the golden langur and a beautiful birding spot centered around two lakes.
- Buxa Tiger Reserve, West Bengal: Lying just across the Sankosh River, it forms a contiguous landscape with Raimona and is known for its trekking routes and historical fort.
- Tamaranga Beel: A large wetland near Kokrajhar, popular with birdwatchers, especially during the winter migration season.
- Kokrajhar Town: The administrative headquarters of the BTR, offering a glimpse into Bodo culture, handlooms, and cuisine.
Traveller Tips
- As tourism infrastructure is nascent, book accommodation in Kokrajhar or Gossaigaon well in advance.
- Carry sufficient cash. ATMs are available in Kokrajhar town but may be unreliable or unavailable closer to the park.
- Mobile network coverage is poor to non-existent inside the park. Inform your family of your itinerary beforehand.
- Hire local Bodo guides. Their knowledge of the terrain and animal behaviour is invaluable and supports community-based conservation.
- Pack light, neutral-coloured clothing, comfortable walking shoes, insect repellent, a sun hat, and binoculars.
- Always follow your guide's instructions during safaris and maintain a safe distance from wildlife.
- Ask for permission before photographing people or their homes. Be respectful of local Bodo traditions.
