Local operator required

Offshore Koh Prins island stop with shallow sandy-bay diving, coral bommies, and deeper outer lines that can run driftier.
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.
