Of all the best liveaboard trips around the world, a dive cruise along with the Similan Islands in Thailand, a Marine National Park, is one of the most affordable options. Most tours take you to the best scuba diving sites in the Andaman sea in less than a week at very budget-friendly prices.
Most of the Similan Island liveaboard boats depart from Khao Lak or the larger city Phuket, which lies about 62 miles further south. From there, the guide will take you to the Similan Islands which are numbered 1 – 9 for easy identification, with the more famous dive sites being Elephant Head, Christmas Point, and East of Eden.
Longer liveaboard schedules for the Thailand Similan Islands tour will take you to the Surin Islands where the popular Richelieu Rock, Koh Bon and Koh Tachai are – good dive sites for beginners and snorkeling. In comparison to the Surin Islands, the Similan Island hot spots are more appropriate for the more advanced scuba divers because there are stronger currents and deeper locations.
