The similan islands are well worth their reputation as one of the best places to dive in the world. The chain of nine islands that make up the similans make for nice easy diving with clear warm waters. Nice sandy bays and excellent viz.
For those who like the "big stuff" Phuket Thailand will not disappoint you. then you should head to the northern end of the similan island national park to the island of Koh Bon. This is a great place to see the Manta Ray. Then head north again you will find the stunning island of Koh Tachai with towering pinnacles and stunning coral gardens. This is the most northern point to the Similan island national marine park. This is depending on who you talk to the best diving in Thailand. Then as the next dive site Richelieu rock is listed as one of the top ten in the world makes Koh Tachai a rare treat to dive. Not only have the best coral gardens and pinnacles but over head keeps your eyes open for the Giant oceanic manta Ray and the largest fish in the ocean the Whale shark. This is the best diving phuket has to offer and boy is it good.
Next stop is the surin islands and richelieu rock. As mentioned before richelieu rock in rated as one of the top ten dive sites in the world. The divesite is stunning and no doubt about it. Many of the similan islands liveboard boats spend two or three dives here. Again this is stunning. Amazing colours, soft and hard corals, massive sea fans and such marine life as you will never see anywhere else. Plus again the Manta ray and Whale sharks are very common here too.
This is why many of the shorter similan island liveaboards are either in the similan islands or in the northern area. Then its only the longer trips or four days or longer that cover all of the best islands in Thailand as you need four of five days to cover them all. If you are thinking of a liveabaord for your dive trip then you do have a lot of thinking to do.
