Chilapata Forest

1. Ecological Highway, Forest Geomorphology & Landscape Corridor

Chilapata Forest is a dense, primeval tract of moist tropical rainforest nestled at an elevation of 75 metres (246 feet) in the heart of Alipurduar district, located approximately 20 kilometres northwest of Alipurduar town and 15 kilometres from Hasimara. While relatively modest in surface area, Chilapata performs an ecological role of monumental importance: it serves as the vital biological migration corridor connecting Jaldapara National Park to the west with Buxa Tiger Reserve to the east.

Without the intact rainforest bridge of Chilapata, the genetic exchange and seasonal migration of large mammal populations—particularly wild Asian Elephants and Indian One-Horned Rhinoceroses—would be completely severed by surrounding human settlements and tea plantations. The corridor allows mega-herbivores to traverse the Bania and Torsa river basins safely during their seasonal food and water foraging cycles.

The forest canopy is dense, multi-tiered, and humid, dominated by gigantic Sal (Shorea robusta), Simul (Bombax ceiba), Chikrasi, and broadleaf evergreen species. Sunlight struggles to penetrate the thick interlocking branches, creating a cool, shadowy realm where wild ferns, epiphytic orchids, and giant lianas choke the understory.

2. Nalrajar Garh: 1,500 Years of Gupta Empire Archaeology

Deep inside the core wilderness of Chilapata lies Nalrajar Garh, an enigmatic archaeological treasure hidden among strangler figs and ancient creepers. According to regional historians and Archaeological Survey of India (ASI) assessments, this ruined fortified settlement was constructed during the Gupta Period around the 5th century AD, during the reign of Emperor Kumaragupta I or Skandagupta.

The ruins consist of massive burnt-clay brick ramparts, ceremonial gateways, defensive watchtower foundations, and an extensive surrounding moat system fed by forest springs. The dimensions and craftsmanship of the large flat bricks (typical of Gupta-era masonry) reveal that this was once a major frontier military garrison and royal sanctuary guarding trade routes between the Gangetic plains and the Kamarupa kingdom of Assam.

Walking silently along the cleared paths around the ruins evokes an atmospheric sense of mystery. Legend holds that King Nala fled to this impenetrable forest citadel during a catastrophic war, with the thick jungle eventually reclaiming the palace over fifteen centuries of oblivion.

3. The 'Bleeding' Ramghuna Tree & Botanical Anomalies

Chilapata is famous for an extraordinary botanical anomaly known locally as the 'Bawa' or 'Ramghuna' tree (Myristica sp.). If the outer bark of this ancient forest giant is gently scratched or nicked, the tree immediately exudes a thick, viscous sap that resembles human blood in color and consistency.

Local tribal folklore holds that these ancient trees bleed to memorialize the soldiers and forest martyrs who fell during ancient battles around Nalrajar Garh. Forest guides demonstrate this phenomenon respectfully to visitors on authorized nature walks, explaining the tree's medicinal chemical properties used in traditional indigenous healing.

The forest is also home to towering Sal trees with massive buttress roots that span dozens of feet across the forest floor, ancient hollow trees that serve as daytime roosts for bats and owls, and rare medicinal herbs catalogued by traditional Mech and Rava medicine practitioners.

4. Chilapata Jeep Safaris, Watchtowers & Bania River

Exploring the interior of Chilapata is conducted via authorized 4x4 open-top Gypsy jeep safaris that depart from the Chilapata Forest Checkpost (Mendabari beat office). The safari track winds through emerald canopies, crossing wooden bridges over the crystal-clear Bania River before halting at the CC Line Watchtower.

The CC Line Watchtower overlooks an open marshy glade and natural mineral salt lick bordered by the Bania stream. From the wooden viewing platform, visitors frequently spot Indian One-Horned Rhinos that have migrated from adjacent Jaldapara, large herds of Indian Gaur (bison), Spotted Deer, and Wild Boar grazing peacefully in the grass.

Leopards are remarkably common in Chilapata, often seen resting along low tree branches during early morning hours. The forest canopy is alive with birdlife: Great Hornbills fly across the forest clearings with deep whooshing wingbeats, while Scarlet Minivets, Emerald Doves, and Asian Fairy-Bluebirds flash brilliant colors among the green foliage.

5. Travel Logistics, Mendabari Eco-Cottages & Seasons

Chilapata is situated along State Highway 12A, making it exceptionally accessible from Alipurduar town (20 km, 30 minutes) and Hasimara (15 km, 20 minutes). Regular passenger buses and shared jeeps connect Alipurduar to Hasimara through Chilapata, though entering the core forest safari routes requires booking an authorized Gypsy at the Forest Department safari counter.

Accommodations are centered around the forest fringe villages of Mendabari and Mathura. The WBTDC and local community co-operatives operate delightful eco-cottages surrounded by organic betel-nut groves and paddy fields. Resort dining features authentic local Bengali and tribal cuisine: fresh river fish, organic country chicken curry, lentil fritters, and steamed rice.

The safari season operates from October 1 to June 14, with the park remaining strictly closed between June 15 and September 15 for the monsoon animal breeding season. The winter months from November to February offer the most pleasant weather and clearest wildlife sightings.
