For lovers of wildlife, few experiences can match the thrill of watching hornbills in their natural habitat. Just 180 kilometers west of Bangkok, in Ratchaburi’s Ban Kha District, Chaloem Phra Kiat Thai Prachan National Park is home to hornbills.
From now until September, hundreds of hornbills—including Great, Oriental Pied, Brown, and Wreathed species—gather in the park’s valleys.

Gliding above dense rainforest canopies, the exotic birds are a spectacular display of color and flight. From the observation hides, you can see them eat, groom and, if you’re lucky, mate.
The Hornbill Trek, organized by Chaloem Phra Kiat Thai Prachan National Park and the Bang Kama Hornbill Conservation Group, invites visitors to immerse themselves in the forest, combining adventure and hornbill conservation.
This community-based eco-tourism offers a front-row seat to one of Thailand’s most pristine wildernesses.
Two Trails, Two Perspectives
Nestled alongside the Kaeng Krachan Forest Complex, a UNESCO Natural World Heritage Site, the hornbill trek is as much about the journey as the wildlife it unveils.
The Hornbill Trek follows two main routes: Pha Rak Kueng Cliff and Pha Ni Chai Rong Cliff, each revealing unique facets of the rainforest ecosystem.

A 6-kilometre round-trip, the Pha Rak Kueng Trail is a two-hour trek from Bang Kama through high hills, streams, forested slopes, and forest valleys.
At the summit, Pha Rak Kueng Cliff towers hundreds of meters above the rainforest, offering stunning panoramic views of the valley below.
From the cliff edge, you can see hornbills feast on wild figs high in the canopy. Their vivid yellow-and-black bills punctuating the green.
From time to time, flocks sweep overhead in synchronized flight, their wings cutting the air with a sound like a chopper hovering over the deep valley.

There are 62 hornbill species worldwide, with Thailand home to 13 of them—one of Asia’s richest hornbill habitats.
From the majestic Great Hornbill to the rare Helmeted and Rufous-necked Hornbills, these iconic birds thrive in the country’s forests, making Thailand a prime destination for hornbill-watching treks.
On this trail, visitors may encounter four hornbill species. The Great Hornbill, with its bold casque and vivid plumage, dominates the canopy with regal presence, while Oriental Pied, Brown, and Wreathed hornbills each contribute their own distinctive charm.
Naturally, hornbills are more than visually captivating—they are ecological keystones.
By dispersing seeds from the fruits they eat, they sustain the forest’s regeneration.
On the Pha Ni Chai Rong Trail, you can observe their complex social behaviors—from cavity nesting to lifelong pair bonds. The trail offers the hornbill enthusiast and visitors an intimate look at the intricate relationships sustaining tropical ecosystems.
Perched on a neighboring peak, the Pha Ni Chai Rong Trail winds through an ecotone, a transitional zone between dry evergreen and mixed deciduous forests at elevations of 700–900 meters.
Along the path, hornbill food trees—Makok Kluean, wild fig, Ta Suea, Krathang Phon Ko, Wa, and Kruai Laem—abound, alongside nesting cavities carefully monitored by local conservationists.
Large cavities host Great and Wreathed Hornbills, while smaller ones shelter Brown and Bushy-crested Hornbills.
For travelers, the trail offers a rare combination of adventure, education, and wildlife observation, providing insight into the careful work of the Bang Kama community to preserve these iconic birds.
Living in Harmony with Nature
The Hornbill Trek is not just an ecotourism initiative—it is a story of community-led conservation.

The Ban Pong Krathing Bon – Bang Kama community participates actively in forest protection while improving their own quality of life.
Nestled in misty valleys, the village offers cool air, lush scenery, and an inviting base for camping or photography.
The surrounding forests form part of the Kaeng Krachan Forest Complex, a vast ecological stronghold teeming with biodiversity.
Thanks to abundant wild fruits, hornbills gather here from July to September to mate, nest, and rear young, making the area a hotspot for researchers and birdwatchers alike.

For visitors, Bang Kama is more than a scenic stop—it is a living classroom demonstrating how humans and wildlife can coexist, and how community stewardship can sustain a delicate ecosystem.
For wildlife photographers, adventurers, or anyone with a curiosity for the natural world, the Hornbill Trek is a journey into the heart of Thailand’s rainforest.
From the towering cliffs of Pha Rak Kueng and Pha Ni Chai Rong to the seasonal gatherings of hornbills in the canopy, every step reveals the forest’s complex beauty.
