Koh Bon liveaboard review

Thanks to Terry and Kathy for these photos taken in February 2016 at Koh Bon, Koh Tachai and Richelieu Rock, we’re glad to hear you enjoyed your trip.

Terry and Kathy joined Oktavia on a 3 day 2 night trip from Khao Lak that skips the Similan Islands to focus on the more northern islands of Koh Bon and Koh Tachai, plus Richelieu Rock which is a submerged pinnacle.

The reason that people love Koh Bon, Koh Tachai and Richelieu Rock is that they are the best dive sites in Thailand for seeing bigger marine life like whale sharks and manta rays. Koh Bon is a manta ray cleaning and feeding station. Richelieu Rock is arguably Thailand’s best dive site with or without whale sharks. Koh Tachai has been the divemaster’s favourite site for several years now, it can be challenging when currents are strong.

Theses dive sites are visited by liveaboard boat from Khao Lak or Phuket during the months of November to May. The ideal months to dive there are late January to April.

The advantage of a liveaboard to Koh Bon, Tachai and Richelieu is that you are on the dive sites at the best times to see the big stuff and you can avoid the day trippers.

The only disadvantage of a liveaboard to these islands is that there is no opportunity for beach excursions. Koh Bon has no beach, Koh Tachai is off limits and Richelieu is just a rock that’s submerged at high tide.
