Similan Islands Liveaboard

Liveaboard Similan Islands

The Similans Islands are noted for being the most famous diving area in Thailand and are one of the most popular sites among those in-the-know.  Unlike other areas for diving in Thailand, it is open for seven months of the year from October 15 through to May 15 in an attempt to preserve the sites and in stark contrast; the weather outside of this period ensures far from ideal conditions for diving!


Diving in the Similan Islands is a fantastic experience and for many people it’s a once in a lifetime journey where you can dive with majestic mantas or come face to face with an awesome whale shark. There are many dive sites around the islands and doing some research before you dive about where you’d like to go is always a good idea!


Some of the more popular Similan Islands diving is East of Eden and Deep Six found off Island 7 and the North Point off from Island 9. Head northeast from Island 9 and the first stop will be an amazing one: Koh Bon. This is one of the most popular sites for day-trippers as it’s one of the most scenic dive spots in Thailand. The island has no beach but it boasts a striking ridge that stretches into the ocean and is the best place for spotting the ocean’s gentlest of giants – manta rays.


Richelieu Rock is by far the ultimate site for divers and is actually part of the Surin National Park but nevertheless is visited by most liveaboards offering Similan Islands diving. It is made up of one main giant rock shaped like a horseshoe that is dramatically surrounded by a few smaller rocks. It is totally submerged except at low tide where it juts out and breaks the surface. Most of the surrounding area is sandy ensuring that a vast array of marine life congregates here and is easy to spot including if you’re lucky enough – whale sharks.
