Hi, my name is Dom and it is my pleasure to help you with all aspects of our Similan Islands Liveaboard booking process.  Below is our form to contact Oktavia Dive Center.

Here at Oktavia we pride ourselves on our customer service and approachability.  Please be assured that you have come directly to the Oktavia Dive Center enquiry page and your request will be handled by me personally 🙂


  • New Marine Park regulations issued by the Similan National Marine Park authorities and Thai government in October 2018 has placed a daily limit on the number of divers allowed within the Park boundaries on any given day.
  • We can only purchase Marine Park Entry Tickets a maximum of 60 Days prior to the return date of any advertised trip. 
  • Guarantee your place to one of Thailand’s most exclusive dive locations by booking a minimum of 60 Days in advance!
