Dehing Patkai is a lowland tropical rainforest in eastern Assam, spread along the Dehing (also spelt Dihing) river and the Patkai foothills. It straddles the Dibrugarh and Tinsukia districts of Assam and reaches toward the Arunachal Pradesh border. The Dibrugarh district administration and Incredible India both call it the “Amazon of the East” for its dense, wet biodiversity. This guide gathers what official and primary sources confirm so you can plan a calm, well-informed trip.
Dehing Patkai National Park is a dipterocarp rainforest straddling Assam’s Dibrugarh and Tinsukia districts, notified as the state’s seventh national park in June 2021. It protects India’s largest stretch of lowland rainforest, home to hoolock gibbons, elephants and hornbills. The best months to visit are November to April.

About Dehing Patkai: quick facts
Dehing Patkai National Park is a protected lowland rainforest in upper Assam, straddling the Dibrugarh and Tinsukia districts and named after the Dehing river and the Patkai hill range. The Dibrugarh district administration describes it as “the Amazon of the East” and records that it harbours India’s largest stretch of lowland rainforest.
The park sits within a wider rainforest belt. The Tinsukia district administration notes the surrounding Dehing Patkai landscape stretches for more than 575 sq km across Dibrugarh, Tinsukia and Charaideo, extending into the Tirap and Changlang districts of Arunachal Pradesh. Visitors enter through forest ranges rather than a single gate, so your plan depends on which side you approach from.

The “Amazon of the East” and the 2021 upgrade
Dehing Patkai is called the “Amazon of the East” by the Dibrugarh district administration and Incredible India, a nickname that reflects its dense, perpetually wet rainforest rather than any formal designation. Incredible India records more than 102 orchid species here, with common canopy trees including ajar, segun (teak), bohot and sam.
The site’s legal status changed in 2021. It was first protected as the Dehing Patkai Wildlife Sanctuary in 2004. The Tinsukia district administration records that the Government of Assam approved its upgrade to a national park on 13 December 2020 and that the Forest Department notified it on 9 June 2021; the Dibrugarh administration and Incredible India give the national-park date as 15 June 2021. Either way, it became Assam’s seventh national park in June 2021, as reported by EastMojo. National-park status confers the highest level of protection under the Wildlife (Protection) Act, 1972.
The park was later opened formally for tourists at a gate near Digboi. The Sentinel reported that the then forest minister inaugurated the entry point under the Digboi Forest Division in Tinsukia district in late 2023, with a main gate built at a cost of about ₹10 lakh.
Wildlife: gibbons, cats, elephants and hornbills
Dehing Patkai is one of India’s richest rainforest habitats, counted by the Dibrugarh district administration as home to about 42 mammal species, 40 reptile species, more than 200 butterfly species and more than 200 bird species. Published fauna lists compiled by zoologist Anwaruddin Choudhury, summarised on Wikipedia, put the tallies higher still, at nearly 50 mammals, 47 reptiles and 310 butterflies.
The headline primate is the western hoolock gibbon. WWF-India describes the western and eastern hoolock gibbons as the only apes found in India, and the gibbon’s duetting calls at dawn are the sound most associated with this forest. Choudhury’s primate survey, as summarised on Wikipedia, lists seven primates here: slow loris, Assamese macaque, stump-tailed macaque, pig-tailed macaque, rhesus monkey, capped langur and hoolock gibbon.
The forest is also notable for its cats and large mammals. Choudhury’s mammal list records seven wild-cat species, naming jungle cat, leopard cat, Asian golden cat, marbled cat, Bengal tiger, leopard and clouded leopard. The Asian elephant is present too; the Tinsukia administration notes the sanctuary was declared an elephant reserve under Project Elephant. For birders, three hornbill species are documented, the great pied, brown and wreathed hornbills, within a recorded avifauna of around 293 species.
| Group | Highlights | Source note |
|---|---|---|
| Primates | Western hoolock gibbon, capped langur, stump-tailed and pig-tailed macaque, slow loris | Choudhury primate list (via Wikipedia) |
| Cats | Clouded leopard, Asian golden cat, marbled cat, leopard, tiger | Choudhury mammal list (via Wikipedia) |
| Large mammals | Asian elephant, deer, flying squirrel | Tinsukia admin; Incredible India |
| Birds | Great pied, brown and wreathed hornbills; white-winged wood duck | Tinsukia admin; Choudhury (via Wikipedia) |
| Butterflies | 200+ species (310 in published lists) | Dibrugarh admin; Wikipedia |
Sightings are never guaranteed in dense rainforest. Gibbons and clouded leopards in particular are shy and more often heard than seen, so treat any encounter as a bonus rather than the point of the trip.
Stilwell Road, Ledo coal and the mining question
The Dehing Patkai belt carries heavy Second World War and coal-mining history alongside its wildlife. The Stilwell Road, originally the Ledo Road, began at Ledo in Assam, on the park’s eastern edge, and was built during the Second World War to carry Allied supplies to China after the Japanese cut the Burma Road. Construction of the Ledo Road began in December 1942, and the route was renamed for the American general Joseph Stilwell in early 1945; it climbed through the difficult Patkai ranges toward Burma.
Ledo and Margherita grew as coalfield towns, and this is where biodiversity and extraction meet uneasily. In April 2020 the National Board for Wildlife approved opencast coal mining on about 98.59 hectares of the Saleki proposed reserve forest, part of the Dehing Patkai Elephant Reserve, which triggered the #SaveDehingPatkai campaign. Deccan Herald and the Sanctuary Nature Foundation reported that conservationists and former wildlife-board members wrote to the environment ministry opposing the clearance. The Assam government announced the sanctuary’s upgrade to national-park status in July 2020, and a one-man inquiry under a retired judge was set up to examine mining in the area. We present this as reported context; the balance between conservation and the region’s coal economy remains contested.
Best time to visit Dehing Patkai
The best time to visit Dehing Patkai is November to April, the cool, drier window when trails are workable and wildlife activity is easier to observe. This is a very wet rainforest, so the monsoon brings heavy rain and waterlogging; sources do not confirm a formal seasonal closure, but access can be limited and uncomfortable in the rains, so reconfirm with the Digboi Forest Division before a monsoon visit.
Incredible India’s Jeypore Rainforest page gives representative monthly temperatures, with January around 10–23 °C and August around 25–32 °C. Mornings are the most rewarding for birds and gibbons, which are most active soon after dawn.
| Season | Months | What to expect |
|---|---|---|
| Winter (best) | November to February | Cool, drier days; best for trails, birding and gibbon activity |
| Spring | March to April | Warm and workable; butterflies active; book ahead for holidays |
| Monsoon | May to September | Heavy rain, leeches, waterlogged tracks; reconfirm access |
| Post-monsoon | October | Lush and humid; conditions improving toward the open season |
How to reach Dehing Patkai
Reach Dehing Patkai through upper Assam, basing yourself near Digboi, Margherita, Jeypore or Dibrugarh. The nearest airport is Dibrugarh (Mohanbari), and the nearest railheads are Dibrugarh and Tinsukia, from where you drive to the forest ranges. The Tinsukia district administration gives the road distance from Tinsukia town to the park as about 59.6 km via NH315.
By air, Dibrugarh (DIB) has regular flights from Kolkata, Guwahati and Delhi; confirm current schedules before booking. By rail, Dibrugarh and Tinsukia are both on the main line and connect to Guwahati and the rest of India. By road, Digboi and Margherita are the usual launch points for the Tinsukia-side ranges, while Jeypore and Soraipung serve the Dibrugarh side.
| From | Approx. road distance | Notes |
|---|---|---|
| Tinsukia town to park (NH315) | about 59.6 km (official, Tinsukia admin) | Verified figure; drive via NH315 |
| Dibrugarh airport to Digboi/Margherita | indicative, reconfirm | Hire a taxi or arrange through your stay |
| Tinsukia to Digboi | indicative, reconfirm | Short hop; Digboi is the usual base |
| Guwahati to Dibrugarh | reach by flight, train or overnight road | Plan via our city guide below |
Many travellers route through the state capital first; our Guwahati travel guide covers onward flights and trains to Dibrugarh and Tinsukia.
Safaris, trails and the Jeypore forest
Dehing Patkai is explored mainly on foot and by vehicle along forest tracks, with the Jeypore (Joypur) reserve forest on the Dibrugarh side among the better-known entry ranges. Incredible India lists activities including trekking, river rafting, camping and elephant rides with trained staff, and gives the Jeypore Rainforest timings as 6 am to 5 pm.
The park does not run a fleet of government safari jeeps the way some tiger reserves do; private or hired vehicles are generally used, and a local forest guide is strongly advised both for wildlife and for navigating the ranges. Walking trails are the best way to experience the rainforest understorey, listen for gibbons and watch for hornbills and butterflies. Because tracks are wet and uneven, go slow, start early and keep groups small.
| Experience | Where | Good to know |
|---|---|---|
| Guided rainforest walks | Jeypore and Soraipung ranges (Dibrugarh side) | Best at dawn for gibbons and birds; hire a guide |
| Jeep/vehicle trails | Margherita range (Tinsukia side), Digboi gate | Private vehicles; no official published tariff |
| Birding and butterflies | Forest edges and river banks | Carry binoculars; peak activity 7–11 am |
| River and camp add-ons | Dehing river; eco-camps | Per Incredible India; arrange through operators |
Permits, entry and Forest Department rules
No inner-line permit is required for Indian visitors to the Assam districts around Dehing Patkai, so entry is managed by the Forest Department at the range level rather than by a separate state permit. Foreign nationals should check current protected-area rules for any onward travel toward the Arunachal Pradesh border, which has its own permit regime.
Official entry and safari fees for the national park are not published on the state tourism or district portals reviewed for this guide as of October 2026. Some travel websites quote small entry charges and per-head jeep rates, but these are inconsistent and unverified, so treat any figure you see as indicative and reconfirm with the forest office. The Dibrugarh district administration lists the Divisional Forest Officer, Digboi Division, as the point of contact for the park; call ahead to confirm current timings, charges, which ranges are open and whether a guide is mandatory.
Standard park rules apply: stay on designated trails, do not feed or crowd animals, carry out your waste, and follow single-use-plastic restrictions. Photography is generally allowed; confirm any camera or drone rules at the gate, as drone use over protected forests usually needs prior permission.
Where to stay
Stay in Digboi, Margherita or Dibrugarh, the three practical bases for Dehing Patkai, with Digboi closest to the Tinsukia-side gate. Options range from simple guesthouses and homestays to a few mid-range hotels and tea-estate bungalows; dedicated eco-camps and forest rest houses near the ranges should be booked in advance, especially in the November-to-April season.
The price bands below are indicative planning estimates for October 2026 and vary by season and demand. Reconfirm current tariffs directly with properties, and ask whether meals and guide arrangements are included.
| Category | Indicative tariff | What you get |
|---|---|---|
| Budget | ₹1,000–₹2,500 | Guesthouses and homestays in Digboi, Margherita, Tinsukia |
| Mid-range | ₹2,500–₹5,500 | Hotels in Dibrugarh/Tinsukia; some eco-camps |
| Upper/boutique | ₹5,500 and up | Tea-bungalow stays and premium lodges around Dibrugarh |
Food to try
Food around Dehing Patkai is upper-Assam home cooking, built on rice, fish and foraged greens. Expect simple, fresh thalis rather than elaborate restaurant menus, especially near the forest. A few dishes worth seeking out:
- Masor tenga (a light, tangy fish curry soured with tomato, lemon or elephant-apple)
- Khar (an alkaline preparation made with sun-dried banana-peel ash, often cooked with vegetables or fish)
- Aloo pitika (mashed potato with mustard oil, onion and green chilli)
- Pitha (rice-flour cakes, steamed or fried, eaten at tea or festivals)
- Laksa and local greens served with red or sticky rice in village kitchens
Assam’s tea is the regional constant; a cup of strong CTC tea is the usual start and end to the day in these districts.
Budget breakdown
A simple three-day Dehing Patkai trip costs roughly ₹8,000–₹16,000 per person on a budget-to-mid plan, excluding long-distance flights or trains to Assam. The estimate below assumes two people sharing, local taxis, guided forest walks and simple-to-mid stays; it is an indicative planning estimate for October 2026 and will move with season, group size and fuel costs.
| Item | Budget | Mid-range |
|---|---|---|
| Stay (2 nights) | ₹2,000–₹3,000 | ₹5,000–₹8,000 |
| Local transport/taxi | ₹2,000–₹3,500 | ₹3,500–₹5,000 |
| Forest entry, guide, vehicle | reconfirm locally | reconfirm locally |
| Meals | ₹900–₹1,500 | ₹1,500–₹2,500 |
| Indicative total | about ₹8,000–₹12,000 | about ₹12,000–₹16,000 |
Forest charges are left as “reconfirm” because no official tariff is published on the portals reviewed; add them once the Digboi Forest Division confirms current rates.
Responsible wildlife rules and practical tips
Responsible behaviour matters more here than usual, because Dehing Patkai is a sensitive rainforest under real pressure from surrounding land use. Keep noise down, never feed or chase animals, maintain distance from gibbons and elephants, and let the guide set the pace. Carry out everything you bring in and avoid single-use plastic.
- Connectivity and cash: mobile network is patchy inside the forest; carry some cash as UPI and ATMs are reliable mainly in Digboi, Margherita, Tinsukia and Dibrugarh, not at the ranges.
- Health: the nearest well-equipped hospitals are in Dibrugarh and Tinsukia; carry a basic kit, insect repellent and any personal medicines.
- Leeches and rain: expect leeches in and after the wet months; wear long trousers, closed shoes and leech socks, and keep rain cover handy.
- Solo women travellers: upper Assam towns are generally calm; travel with a known guide or operator for forest walks, start early and return before dusk.
- Packing by season: light layers and a warm top for winter mornings, quick-dry clothing and rain gear for shoulder and monsoon months, plus binoculars and a torch.
