Before sunrise the forest keeps its own clock: long calls thread the canopy and dew beads on lianas. You meet your Bunong guide and researchers at the edge of Keo Seima Wildlife Sanctuary near Sen Monorom, then step into semi-evergreen rainforest where the morning chorus—gibbons, hornbills, and peafowl—sets the pace.

Before sunrise the forest keeps its own clock: long calls thread the canopy and dew beads on lianas. You meet your Bunong guide and researchers at the edge of Keo Seima Wildlife Sanctuary near Sen Monorom, then step into semi-evergreen rainforest where the morning chorus—gibbons, hornbills, and peafowl—sets the pace.
Keo Seima protects lowland and hilly forest across Mondulkiri and stretches into neighboring provinces. The landscape here is shaped by ancient sandstone outcrops, seasonal streams, and broad ridgelines that funnel wildlife along predictable routes. The Bunong people have lived and foraged in these forests for generations; many guides combine ancestral knowledge with modern monitoring techniques to track family groups of southern yellow-cheeked gibbons and document other species like black-shanked douc langurs and peacock-pheasants.
Expect a full-day field experience: early-morning tracking when gibbons vocalize, a simple breakfast in the trees, mid-day jungle trek to waterfalls, and an afternoon of wildlife spotting before a pause at Bamboo Camp. Trails are undulating with some muddy sections in wet months; distances covered during the day are typically several kilometers over mixed terrain with occasional steep sections.
Practical guidance: start before dawn, carry layered, quick-dry clothing, bring insect protection and at least 2 liters of water, and move quietly—sightings depend on patience. Photography requires a telephoto lens and fast shutter speeds for canopy subjects. The outing blends immersive wildlife viewing with on-the-ground conservation, offering both close observation and context about protection efforts in Cambodia.
