Thailand Liveaboards Highlights

Thailand liveaboards head 30 miles off the countrys west coast to the nine Similan Islands, which cover an area of approximately 87 square miles and offer some of the best liveaboard diving in the Andaman Sea. In combination with the northern islands of Ko Bon and Ko Tachai and the world-famous Richelieu Rock, a Similan Islands liveaboard trip provides access to an impressive catalog of marine species and often easy diving in comfortable conditions.

Previous problems with over-tourism and damage to the land and marine ecosystems of the islands have been brought under control in recent years through stricter access rules and the removal of virtually all land-based accommodation and tourist facilities. [1] As such, the Similan Islands liveaboard season runs from mid-October to mid-May in line with the National Park open season, and it is prohibited to venture onto several of the most vulnerable islands.

While day trips are possible, a liveaboard is by far the best way to experience this intriguing region. Departing from Khao Lak, Ranong, or Phuket, liveaboards to the Similan Islands tend to run 4 or 7-night itineraries with longer trips, including dives at Richelieu Rock or the nearby Surin Islands. Some Similan Islands trips include , a unique and rarely visited destination. Boats range in style from modern motor yachts to more traditional-style junks and in price from budget-friendly to luxury. Most schedules will run 4 dives daily, including one dusk or night dive. There is also the option to snorkel between dives and the possibility of a land-based excursion to explore the top-side wildlife.

With marine biodiversity now declared fully recovered, divers will discover diverse and prolific fish life, including large schools of anthias, damselfish, butterflyfish, and angelfish schooling over healthy colorful coral formations and gently sloping reefs. Dramatic rock formations on the west side of the islands create a fascinating underwater topography of tunnels, caves, and swim-throughs. Nutrient-rich currents encourage vast populations of gorgonians, soft corals, and crinoids. Manta rays and whale sharks are frequent visitors between December and April.
