Koh Bon North Reef offers a sloping reef with hard corals transitioning to a sandy bottom (10-30m). This relaxed dive is great for beginners and offers good visibility. While mantas frequent the West Ridge, this side provides ample reef fish, including barracudas and moray eels.

This dive site is actually between Koh Bon Bay and West Ridge. A good place to jump from the boat into the water, as you can dive without currents. Viewing the waterfall from below is a natural spectacle in itself.

Nice shallow area for diving with a slightly sloping reef. You can swim from the North Ridge over the West Ridge and into the bay. Currents are usually weak to moderate.

Koh Bon East Side offers a sloping reef with hard corals transitioning to a sandy bottom. It’s often where you find leopard sharks resting. While the main attraction is the West Ridge for manta rays, the East side provides a more relaxed dive with abundant reef fish and good visibility.

This point is located northeast of the 9th island in the Similan Islands. It is named after the three large trees that are used to mark the entry, from a shallow depth of about 5 meters to a reef slope of about 18 meters, beyond which there is a pure white sandy area dotted with isolated roots. Offshore, there are beautiful rocky areas with schools of soft corals, where you can see large fish. Because the tide splits on the island, the tide is clear and you can enjoy drift dives when the tide is strong.

Breakfast Bend is a very elongated reef. It is slightly sloping with a max depth of 35m. The upper part is full of hard corals, then from 16/18m there is more sand with isolated coral blocks that are beautifully covered in glassfish.

As the name suggests, North Point is the northernmost dive site in the Similan Islands, located on the north side of Island 9. The terrain is varied, with massive granite overlaps forming large walls, channels, and swim-throughs.

Island#9 is the most northern island of the main Similan island cluster. There are many dive sites around the island ranging from quiet bays, drift dives in channels, pinnacles of giant granite boulders, and sweeping reefs.
