South Siam 3 - Similan Islands and Richelieu Rock

South Siam 3 runs twice weekly 3 day / 2 night trips to the Similan Islands, Koh Bon, Koh Tachai, Surin islands and Richelieu Rock. Divers can make a longer trip by starting on the right day (ask us for details - see more information and prices below). The South Siam boats are low budget options but are about the only option for a short 2 night trip that includes the amazing Richelieu Rock. 2 day / 1 night trips are possible starting most days with diving at the Similan Islands and Koh Bon. Overnight trips do not include Tachai or Richelieu Rock. Trips begin almost any day during the high season (late October - early May), but if you want a 3 day / 2 night trips including Richelieu then you must start on Wednesdays or Sundays (South Siam 3) or Saturday or Tuesday (South Siam 4). The South Siam 3 and South Siam 4 boats are built to almost the same design, sleeping 28 guests maximum. The boats can be crowded on some days as there may also be day trippers on board.

NOTE: The South Siam Similan Islands operation has no trips for the 21/22 season available at this moment.
