The coastline of Khao Lak, just north of Phuket, has a few pretty good dive sites, but the must-see sites are around the islands nearby, specifically the Similan and Surin Islands. They're considered among the best dive sites in the world. As you can’t easily stay on these islands, Khao Lak is a good place to base yourself when you’re not out on the ocean.
Both of these diving hotspots are part of an expansive marine national park, featuring perfect visibility and amazing coral reefs. Some sites offer more challenging swells and currents for those who have a little more experience, but the rewards include leopard and whitetip sharks, turtles and giant bumphead parrotfish.

However, Pattaya can be dived all year round, instead of only in the high season as is the case in many of the above destinations. Also, it has no less than 5 shipwrecks within recreational diving limits, including 3 ex-Royal Thai Navy troop transports sunk as artificial reefs and a genuine war wreck from 1945.
