Similan Islands Diving

Liveaboard diving in the Similan Islands is breath-taking, which is why many scuba divers come back year after year. If you love shark diving, the Similan Islands don’t disappoint, as you can spot whale sharks, whitetip sharks, blacktip reef sharks, leopard/zebra sharks, guitar sharks, nurse sharks, bull sharks and the infamous tiger shark.

On top of diving with sharks, you can dive amongst huge granite boulders with caverns and arches accompanied by large schools of fish and you may meet Napoleon Wrasse too.

There are strong currents in this region, which means you need to be an experienced diver with an advanced diver certification. Then you also have the chance to enjoy a night dive or two, which is when you get to see those underwater creatures that come out at night.

Richelieu Rock Diving

Richelieu Rock is one of the best dive sites in Thailand, and is an isolated pinnacle about 10km (6.25 miles) east of Surin Islands and 100km (62.5 miles) north, north east of the Similan islands.

It is only the very top of the rock that will be visible at low tide and presents as a shipping hazard, as it is submerged at high tide.

It is when you dive below the surface, after jumping in from the dive liveaboard, when the true wonder of Richelieu Rock becomes apparent. The rock is in a rough shape of a horseshoe and is made up of several rocks, pinnacles, overhangs and small caves. The maximum depth is about 35 meters (115 feet) to the bottom, but most dives are at between 20-28 meters (92-99 feet).

Richelieu Rock is a limestone pinnacle that slopes steeply down to the bottom on its north and west side. Richelieu Rock attracts whale sharks and manta rays due to the upwellings that are rich with plankton. But this dive site is also home to many pelagic fish including barracuda.

But then in between the excitement of the large pelagics, whale sharks and manta rays, don’t forget to enjoy Richelieu Rock’s purple soft corals and sea fans.


Surin Islands Diving

The Surin Islands has one of the highest hard coral diversities in Thailand, not to mention the small cove beaches and great snorkelling sites for those non-divers onboard.

Mergui Archipelago Diving

Mergui Archipelago of Burma is in the north of Andaman dive area. This dive area was only opened to divers in late 1990, and is still very much an undisturbed ecosystem.

Mergui Archipelago is best suited to experienced divers as it is a remote location with currents and open water diving. These north Andaman liveaboards operate between October to May when you have the best visibility and surface conditions.

South Andaman Diving

Some of the best dive locations in south Andaman are Hin Daeng and Hin Muang. These are two underwater pinnacles that are covered with anemones, sponges and sea fans. But you may be also lucky to see whale sharks and manta rays in this area too.

But be aware that there are strong currents here too, which is suited to experienced divers. The south Andaman liveaboards also visit Koh Ha and Koh Rok, which are uninhabited islands with white-sand beaches. But under the surface, you’ll discover one of the best-preserved coral reefs in the country.

Manta Rays and Whale Sharks in Thailand

To enjoy liveaboard diving with manta rays and whale sharks in Thailand, the best dive sites are Koh Tachai, Koh Bon, Richelieu Rock and the Similan Islands.

Best Time To Dive Thailand

The diving in Thailand is year-round so there’s no best time to dive. Having said that, peak Thailand diving season for the Gulf of Thailand is from May through September and for the Andaman Sea is from October through April. There is great visibility, which is up to 30 metres (99 feet).
