Koh Bon is just off Similian Island near Khao Lak. The water is clear and warm. However, every now and then a cold current can come up and be fairly strong so take caution. The reef is beautiful and full of colorful marine life.

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.

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.

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.
