Koh Moan

Koh Moan is an intermediate dive site around a small island in Cambodia's Gulf of Thailand waters, where a rocky reef descends to 20 meters over a landscape of boulders and coral formations. The island's position between deeper channels means currents can develop, bringing nutrient-rich water that supports healthy coral growth and abundant fish life. The reef features a good mix of hard and soft corals, with barrel sponges adding vertical interest. Schools of batfish are a highlight, approaching divers with their characteristic flat-bodied curiosity. Barracuda cruise the deeper water beyond the reef edge, and bamboo sharks rest in sandy hollows. The macro life is excellent — nudibranchs, flatworms, and tiny commensal shrimp on sea urchins reward patient observers. Koh Moan's intermediate conditions offer a balanced dive experience, with enough current-driven encounters to excite while remaining manageable for competent divers.
