Similan Islands Liveaboard - Diving Topography

Similan Liveaboard Diving topography Eastern Side

The underwater topography of Similan Islands differs between the eastern and western sides of the islands.

In general, the east facing dive sites feature gently sloping reefs and drop-offs with impressive gardens of sea anemones, flourishing hard and soft corals, and teeming fish populations. With negligible currents and mostly moderate depths, these dive sites are suitable for almost any level of diver.

The sheltered conditions are ideal for scuba divers.


Western Side

Similan Islands Liveaboard - Diving Topography Western Side

Similan Liveaboard Diving topography Western Side

The western side of Similan Islands is quite the opposite. Here giant boulders tumble down to the seabed in depths of more than 40m.

Currents have kept the gaps between the boulders free from build-ups of sand, leading to the development of tunnels, arch-ways, and caverns that provide exciting swim-throughs.

The currents also provide nutrients for masses of gorgonians, crinoids, sea fans and lush soft corals.

Similan Islands Liveaboard diving season

The season for Liveaboard diving in Similan, Koh Bon, Koh Tachai and Richelieu Rock begins in November and ends the first week of May. The rest of the year, Similan Islands are closed to Liveaboard diving activities.

There’s also a selection of rays including eagle, marbled and enormous but graceful Manta Ray. With dive spots, such a Koh Bon, Koh Tachai and Richelieu Rock, Similan Liveaboard diving holiday in Thailand is a fantastic adventure. With All 4 Diving, your Similan Islands Liveaboard diving holidays will be the most amazing and unforgettable in Thailand.
