The Tatai River in Koh Kong province is one of Cambodia's most picturesque and ecologically pristine destinations. Meandering through the foothills of the dense Cardamom Mountains, Phnom Kravanh, the region offers an immersive escape into untamed nature. The surrounding evergreen rainforests and mangrove estuaries serve as a critical habitat for diverse species, including pileated gibbons, hornbills, kingfishers, wild boars, fishing cats, and rare freshwater otters. Because the Tatai basin benefits from ongoing conservation initiatives, its waterways remain remarkably clear, feeding downstream into coastal ecosystems. Motorized wooden boats cruise along the wide meanders of the Tatai, taking travelers upriver toward Tatai Waterfall or downstream to explore surrounding mangrove systems. Taking a boat journey at sunrise or sunset offers breathtaking views as mist rises off the water and the peaks of the Cardamom Mountains are cloaked in soft white clouds. Local rangers and community guides lead hikes ranging from easy forest walks to multi-day wilderness treks through old-growth rainforest. Eco-travelers can camp near riverbanks, stay in sustainable tented safari camps, or lodge at low-impact floating resorts anchored directly on the river waters.
