Koh Yawabon - Similan Islands

Koh Yawabon, tucked away in the Similans, feels a bit like a well-kept secret. While most boats head elsewhere, we often find ourselves drifting past schools of fish so dense they shimmer, completely unfazed by our presence. Keep an eye out for lobsters tucked into the crevices and Kuhl's stingrays gliding along the sandy patches. The big draw here is the swim-through, but it’s a serious commitment: long, dark sections and strong currents mean you’ll need specific training to go beyond the entrance. For many, just exploring the exterior, with its relatively quiet atmosphere and abundant fish life, is reward enough.
