Similans - Richelieu Rock
South Siam 4 is almost as flexible as our other liveaboard boat, South Siam 3. On South Siam 4 you can get on and off the liveaboard boat 5 days a week compared to South Siam 3’s 7 days a week, but on South Siam 4 you get to go to Richelieu Rock and Koh Tachai as well as Similans and Koh Bon.
Our liveaboard boats stay around the Similan Islands for the season, unlike other liveaboard boats that travel from and to Phuket on fixed schedules. We transfer new guests to our liveaboard boats by minibus and speedboat every day of the week.
South Siam 4 dives around the Similans every day of the week except Wednesdays and Sundays when she goes up to Richelieu Rock, Koh Tachai and Koh Bon for the day.
To visit Richelieu Rock you need to do 3 or more days on South Siam 4, spanning a Wednesday or Sunday. For example, join the boat on Monday or Tuesday and get off on Thursday, Friday or Saturday or get off the following Monday or Tuesday to visit Richelieu Rock and Koh Tachai twice.
