The islands are all conveniently numbered from south to north.

These islands are home to the oldest coral reefs in Thailand and are approximately 5,000 years old. The first three islands are inaccessible to the public for the sake of preserving turtle nesting beaches. The other islands, while accessible to the public, are respected areas and accommodate few overnight visitors beyond those on the liveaboards. While all of the islands are beautiful and each worthwhile if you have the time to explore them all, the most famous of the islands are Ko Similan, Ko Huyong, and Ko Pa Yu. Part of the Phang Nga province, the Similan Islands are one of Thailand's many national parks. The marine world that the Similan Islands hosts is extraordinary and varied. The west side of the islands have large coral boulders while the east side is known for its sloping coral reefs.

The different corals come together and form sloping reefs on the east side of the islands while on the west side of the islands form massive coral boulders, often resembling many commonplace objects (read: Elephant Rock).

        Colorful reef fish dance between the corals - like anemone fish, oceanic triggerfish, titan triggerfish, and oriental sweetlips. Smaller finds of the invertebrate variety including the dazzling harlequin shrimp and many nudibranchs as well as a few larger invertebrates like cuttlefish and the impressive giant jellyfish that can be found here. Some other unique finds in the islands include sea snakes, seahorses, stonefish, giant groupers, blue-spotted Kuhl´s and endless more. Some of the larger animals that frequent these waters are turtles, white and black tipped reef sharks, manta rays, bottlenose dolphins and the occasional whale shark.
