3- Day 2 night Gibbon watching in Mondulkiri

Tour Highlights

Hidden deep within the vast wilderness of Keo Seima Wildlife Sanctuary lies an immersive journey that stirs the senses and reconnects you with nature at its most raw. This three-day expedition leads you through primeval rainforest alive with rare and secretive wildlife, from the haunting dawn songs of the endangered southern yellow-cheeked crested gibbons to the silent glide of nocturnal creatures beneath the moonlit canopy. Accompanied by skilled Bunong trackers, you will move through dense jungle corridors, discover secluded waterfalls, and gain insight into an indigenous culture that has lived in balance with the forest for generations.

Your adventure begins at first light in Sen Monorom, before descending into the heart of the rainforest where towering trees and the chorus of birds quickly surround you. A morning trek offers the chance to witness northern pig-tailed macaques racing through the branches and the striking colors of green peafowl flashing across the forest floor. After a riverside jungle lunch, the afternoon is dedicated to wildlife tracking, following subtle signs that may lead to sightings of black-shanked douc langurs or the elusive clouded monitor lizard. As evening settles in, you’ll reach the remote jungle campsite, enjoy a hearty dinner, and set out on a guided night walk, scanning the darkness for glowing eyes—perhaps a pygmy slow loris or a masked palm civet slipping quietly into the undergrowth.

begins before sunrise as the forest awakens to the echoing calls of gibbons drifting through the mist. Led by your guide, you’ll track these agile primates as they swing effortlessly through the treetops. After breakfast, the journey continues deeper into the sanctuary on a full-day trek, where every step carries the possibility of encountering yellow-throated martens, great hornbills, or even signs of sun bears and leopard cats. A picnic lunch beneath ancient trees offers a short rest before the trail resumes. As night falls, a campfire dinner unfolds beneath a sky painted in deep sunset hues and scattered with stars, creating a perfect moment to share stories and absorb the rhythm of the jungle.

The final day shifts focus on cultural discovery and reflection. After a relaxed morning at camp, you’ll trek toward a traditional Bunong village, passing through rolling hills and panoramic jungle landscapes. Here, you’ll learn about the community’s ancestral knowledge, including traditional agriculture, medicinal plants, and sustainable forest use. A hidden waterfall provides a refreshing escape and a memorable jungle meal before the afternoon reveals spiritual practices, sacred traditions, and the craftsmanship behind handmade tools and textiles.

As the journey concludes, a final walk through the forest offers time to reflect on unforgettable wildlife encounters, the wisdom of the Bunong people, and the untamed beauty of Keo Seima Sanctuary.

Whether you are drawn by wildlife, culture, or the call of the wild, this multi-day trek offers a rare and deeply rewarding way to experience one of Cambodia’s most extraordinary natural sanctuaries.
