MV Oktavia – Snorkelling

We have had a very long and proud history of providing the best in snorkel liveaboard cruises on board MV Oktavia.  However, new regulations issued in October 2018 by the Similan National Marine Park Authorities and Thai government have placed heavy restrictions on the ability of liveaboard boat operators to offer overnight snorkel options within the Park’s boundaries.

Non-diving guests have and always will be very welcome on-board MV Oktavia, so please do contact us for more information if you have non-diving friends or family within you group who would also like to join our trip.
