Similan Islands Diving and Liveaboards



Due to the current challenges facing all nations and in response to governmental direction and advice, Oktavia Dive Center has taken the decision to suspend all business until further notice.

Whilst highly regrettable, we do this in the interest to protect our both our Guests and Staff during these testing times.

As a result Oktavia Dive Center will not be publishing the MV Oktavia cruise schedule for the 2020-2021 Season until a time that it is deemed safe and viable to do so.
