Koh Moan
Remote Koh Prins reef island with shallow bay and drift options.
Local operator required
Boat access is operator-led, so plan Koh Moan through a remote offshore dive trip rather than independently.
About Koh Moan
Koh Moan is a remote Koh Prins group reef island with a shallow bay, coral bommies, and outer reef lines that can shift from easy to driftier as you move around the island. The site stays flexible enough for beginner-friendly bay dives, but the outer routes add more current and more payoff for divers who want to explore beyond the shallow line. It is a remote offshore day trip rather than a quick near-shore reef stop.
