Koh Bon Phuket private boat is a trip that serious divers know well — and one most general tourists have never heard of. Koh Bon isn’t an island with a beautiful beach for sunbathing. It’s a dive site famous for walls of vibrant purple and orange soft coral, and one of the highest Manta Ray encounter rates anywhere in Andaman waters.
Picture this. Descending into clear water to find a wall covered in soft coral so vivid it looks painted. Colorful reef fish moving through the scene. And if conditions align, the unmistakable silhouette of a Manta Ray gliding overhead.
Koh Bon Phuket private boat through a private Yacht Charter Thailand is the best way to access this world-class dive site.
Where Is Koh Bon and How Long Does It Take to Get There?
Koh Bon sits within the Similan Islands National Park, well north of Phuket. From Phuket, it’s approximately 2.5–3 hours by fast boat — a day trip is possible but requires a very early departure. From Thap Lamu Pier (Phang Nga), it’s significantly closer at approximately 1–1.5 hours, which is why most Koh Bon trips depart from the Phang Nga side rather than directly from Phuket. An experienced charter team can plan the right route either way.
Why Koh Bon Is Special for Divers
- Some of the best soft coral in the Andaman. Koh Bon’s underwater walls are covered in dense, healthy soft coral in shades of purple, pink, and orange — one of the most sought-after locations for underwater photographers in the region.
- High Manta Ray encounter rate. Koh Bon has one of the
- highest recorded Manta Ray sighting rates in Thai waters, particularly from November through April.
- Currents that sustain the ecosystem. Currents bring large amounts of plankton, allowing soft coral to flourish and attracting larger marine life — though currents can be strong in places, better suited to experienced divers.
- Excellent water clarity. Underwater visibility is typically good to excellent, especially during High Season.
Who Is Koh Bon Best Suited For?
Well suited for experienced divers (currents and depth at certain points require Advanced certification or higher), underwater photographers, and groups prioritizing diving over beach time. Not well suited for beginner divers, families with young children, or anyone wanting a relaxed beach day.
How to Plan a Koh Bon Trip for the Best Experience
- Choose the right season. November through April is High Season — calmer seas and the best chances of Manta Ray sightings. The Similan Islands National Park typically closes from May to October; check current park status before planning.
- Consider an overnight trip. Given the distance, an overnight charter combining Koh Bon with other Similan Islands dive sites offers significantly better value than a day trip.
- Brief your dive experience level in advance. This allows the charter team to plan dive sites appropriate to the group’s certification level.

Koh Bon Phuket private boat is not a trip for everyone — but for divers who want to see some of the Andaman’s most vivid soft coral and have a real chance of encountering Manta Rays, it’s one of the most rewarding destinations in the region.
