Similan budget liveaboard diving 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 Rock then you must start on Wednesdays or Sundays (South Siam 3, SS3) or Saturday or Tuesday (South Siam 4, SS4).
For the best experience recommended trip duration should be at least 3 days/3nights and to improve your changes to see Mantas and Whale Sharks Koh Bon, Koh Tachai and Richelieu Rock should be part of the itinerary.
The diving in the Similan National Park, Koh Bon, Koh Tachai and Richelieu Rock can be demanding due to strong currents and depths of the dive sites. It is recommended that you are at least Advanced Open Water Diver and Preferably Nitrox Certified before booking your trip. You can also do the course during your trip.
Due to the diver quota enforced in the Similan National Park, we need to confirm availability for each trip. The National Park fees are also not included in the price and they must be payed when entering the park depending on your chosen duration of stay. The Similan budget liveaboard usually has some availability, but advance bookings are highly recommended due to the high demand during the Similan National Park diving season.
