Hoollongapar Gibbon Sanctuary

A small, isolated forest fragment near Jorhat, providing a crucial refuge for India's only ape, the hoolock gibbon, and a remarkable density of primate species.

Long before the sun fully clears the horizon, the forest begins to sing. It’s a sound unlike any other in India—a rising, whooping chorus of calls that echo for kilometres. This is the morning duet of the hoolock gibbon, India’s only ape, and the signature experience of this compact sanctuary. The sound is your compass, guiding you along forest trails under a canopy of Hollong trees, for which the park is named. In this small patch of green surrounded by tea gardens and villages, you are in one of the most important primate habitats in the country.

History & Context

The forest’s story began in 1881 when it was established as the Hollongapar Reserve Forest. For over a century, it remained a pocket of biodiversity even as surrounding lands were converted for agriculture and tea cultivation. A significant event in its history was the construction of a railway line that cut directly through the forest, fragmenting the habitat. Recognizing its immense ecological value, particularly for its primate populations, the government of Assam upgraded its status, and on July 30, 1997, it was officially declared a wildlife sanctuary. Its small size, just under 21 square kilometres, makes its conservation status both critical and precarious.

What Makes It Distinctive

The primary distinction is its celebrity resident: the western hoolock gibbon (Hoolock hoolock). This is the only place in India where you are almost guaranteed a sighting of an ape. The sanctuary's small area and the gibbons' loud, territorial calls make them relatively easy to locate with a knowledgeable guide.

Beyond the gibbons, the sanctuary is remarkable for its primate density. Seven of the fifteen primate species found in India live here. Alongside the hoolock gibbon, you can find the stump-tailed macaque, northern pig-tailed macaque, eastern Assamese macaque, rhesus macaque, capped langur, and the nocturnal Bengal slow loris. Seeing multiple primate species in a single morning walk is a common occurrence, making it a world-class destination for primate enthusiasts.

A unique and visible conservation challenge is the broad-gauge railway track that bisects the park, creating a dangerous barrier for arboreal creatures. To mitigate this, a semi-artificial canopy bridge was constructed over the tracks, providing a vital connection for the gibbons and other canopy dwellers between the two sections of the forest. Observing this bridge is a lesson in modern conservation solutions.

Best Time to Visit

The best period to visit is from October to March. During these post-monsoon and winter months, the weather is pleasant, rainfall is minimal, and the forest trails are dry and accessible. Wildlife, especially the primates, is very active in the cool morning hours.

April and May can be hot and humid, though sightings are still good. The monsoon season, from June to September, sees heavy rainfall, making trails slippery and leech-infested. While the forest is lush, the challenging conditions make this period less ideal for most travellers.

How to Reach

By Air: The nearest airport is Jorhat Airport (JRH), located about 25 km from the sanctuary. It is well-connected with daily flights from Guwahati and Kolkata. Taxis are available at the airport for the 45-minute drive to the sanctuary entrance.

By Rail: The closest major railway station is Mariani Junction (MXN), just 5 km away. Several trains from Guwahati and other parts of India stop here. From Mariani, you can hire an auto-rickshaw or taxi for the short journey. Jorhat Town Railway Station (JTTN) is another option, about 20 km away.

By Road: The sanctuary is located at Meleng, about 20 km from Jorhat town. The drive takes approximately 45-60 minutes. Jorhat is well-connected by road to major Assamese cities like Guwahati (around 310 km / 7-8 hours) and Dibrugarh (around 140 km / 3-4 hours).

Traveller Tips

Arrive at the gate right at opening time. The gibbons are most vocal and active in the first two hours after sunrise.
Hire a registered local guide. Their expertise in identifying calls and spotting camouflaged wildlife is invaluable.
Wear neutral-coloured, full-sleeved clothing and comfortable walking shoes.
During and after the monsoon (September-November), wear leech-proof socks as a precaution.
Carry cash. There are no ATMs at the sanctuary, and you will need it for entry fees, guide fees, and any local purchases.
Mobile connectivity is weak to non-existent inside the park. Inform your contacts of your plans beforehand.
Bring a good pair of binoculars and a zoom lens for your camera. Maintain a respectful distance from wildlife and avoid using flash photography.
Most visitors stay in Jorhat, which offers a range of hotels. A few eco-homestays are located closer to the sanctuary for a more immersive experience.

Living Roots Expert Notes

We always plan our visits to Hoollongapar to coincide with the gate opening. The first hour of daylight is magical; the air is cool and filled with the powerful, cascading calls of the gibbon families. This auditory experience is often more memorable for our guests than the sighting itself. A good local guide is non-negotiable here; they don’t just find the animals, they interpret their behaviour and the complex social dynamics you’re witnessing.

Our guests are always surprised by how small and isolated the sanctuary feels, like an island of ancient forest in a sea of tea. This visual makes the conservation challenges very real. We make it a point to walk towards the railway line to see the canopy bridge. It serves as a powerful talking point about how human infrastructure and wildlife can, with effort, coexist. It’s a tangible symbol of hope and ingenuity that resonates deeply.

Ethically, it's about being a quiet observer. The gibbons and macaques are used to human presence but not interference. We insist on small groups, quiet movement, and absolutely no feeding or loud noises. The goal is to leave the forest and its inhabitants exactly as we found them, ensuring this precious primate haven endures.
