First of all, South Siam Divers (SSD) operate 2 Similans Liveaboards to The Similan / Surin / Richelieu Rock which run throughout the open season. Because of this South Siam Divers are the only operator that can offer you ANY number of days and nights and therefore fit into your hard-earned Phuket scuba diving holiday!

So, how do they manage to do it? And most of all, how do they make it easy?

Because both South Siam Divers Similans Liveaboards stay moored in The Similan Islands. Consequently, unlike other Similan Liveaboards with fixed schedules, Indepth can arrange your Similan / Richelieu Rock experience for either just one day, or one week or even one month!

Hence South Siam 3 (SSD3) can conduct scuba diving around the Similan Islands almost every day of the week. This is except Wednesdays and Sundays as she heads up to The Surin islands. Therefore you can also experience the world-famous Richelieu Rock, Ko Tachai and in addition Koh Bon dive sites which are dived on those days. And if you need a tune up dive before your Liveaboard you can dive Phuket with South Siam Divers on our Phuket Day Trip Boat 3.
