Thailand Liveaboard Diving Holidays

Diving Thailand

When diving in Thailand there are loads of places and ways to do it. You can dive from the beach go on a day trip boat for the islands nearby but the most popular are the liveaboards where you can dive from 4 days up to a week while cruising around on the Andaman Sea.

A Thailand liveaboard has two areas where they make cruises. The most famous are the Similan islands where the nine islands have dive sites on the West coast made from massive granite boulders with some great swim troughs where can see macro such as pygmy pipe horse, ribbon eels and plenty of nudibranchs. The East coast of the Similan is more reef diving where you see turtles, leopard sharks and Napoleon wrasses.

Not part of the Similan but not to be missed during your Similan liveaboard cruise are Koh Bon, Koh Tachai and the Surin islands. These 3 places are more for the bigger fish of the ocean. Koh Bon is a famous cleaning station for manta rays and some early morning dives bring you sharks. Tachai pinnacle is famous for its strong currents what brings in all kinds of pelagic fish as well as manta rays and whale sharks. Near the Burmese border, you have without a doubt the best dive site of Thailand. Richelieu Rock is a limestone pinnacle that is covered with soft corals and huge sea fans. Here you can see everything from ghost pipefish, seahorses, harlequin shrimps, schools of snappers, yellowtail barracuda and even whale sharks sometimes pass by.

Another great place for liveaboard diving in Thailand is the South Andaman what includes Koh Lanta, Koh Phi Phi and Krabi. Around this area, you will see that the dive sites and islands consist out of limestone. This brings along beautiful soft and coral growth large chambers and caverns and for marine life, it is similar to the Similan with cleaning stations for Manta rays and whale sharks. Also, the smaller critters such as harlequin shrimps, seahorses and nudibranchs are found here. The visibility is not always as good in the Southern Andaman but the lack of other divers sure makes up for it.
