Similan Islands

Located in the crystal-clear waters of the Andaman Sea, the Similan Islands are the crown jewel of Thailand liveaboard diving. Known for their world-class dive sites, pristine reefs, and diverse marine ecosystems, these granite islands offer a rich and rewarding underwater experience for divers of all levels.

The Similan archipelago consists of nine main islands (with two additional protected islands), each surrounded by unique underwater landscapes. From giant granite boulders and dramatic swim-throughs to gentle coral slopes and white sandy bottoms, the variety of dive profiles keeps every dive exciting.

Top dive sites include:

• Elephant Head Rock – Famous for its maze-like rock formations, archways, and strong currents, it’s a hotspot for giant trevally, white-tip reef sharks, and pelagic encounters.
• West of Eden – A vibrant coral garden filled with sea fans, anemones, and rich macro life like nudibranchs, pipefish, and scorpionfish.
• North Point & Christmas Point – Ideal for drift dives along boulder-strewn terrain, where large fish like Napoleon wrasse and marbled groupers are frequently seen.
• Beacon Reef – A great multi-level site for newer divers and photographers alike, known for its hard coral gardens and reef critters.
• Deep Six – A deeper, more advanced site offering sightings of rays, moray eels, and the occasional manta ray.

The Similan Islands are especially renowned for their exceptional visibility, often exceeding 30 meters, and the sheer variety of marine life, from tiny frogfish and seahorses to large barracudas and reef sharks. The islands are also visited seasonally by manta rays and whale sharks, making them a favorite stop for big-animal lovers.
