Thailand’s Andaman Sea is world-famous for liveaboard diving. Whale sharks, mantas and beautiful corals can all be encountered for a bargain price in the Similan Islands and surrounding waters.
While scuba diving is a popular pastime throughout coastal Thailand, the best sites in the Land of Smiles is found near remote islands in the Andaman Sea. Liveaboards travel to the south islands, but the real heavy hitters are the Similan Islands, Koh Bon and Richelieu Rock. Only accessible by liveaboard, you’ll find some of the best dive sites for whale shark and manta ray encounters in these waters. The reef life is also prolific as these islands have been protected as a marine park since 1982. You might spot mantis shrimp, scorpionfish and blue-spotted stingrays. Typical liveaboard itineraries last 4 to 10 days, and the best time to dive by liveaboard in Thailand is from November to May.
