“Great Similan islands diving trip, from first email to the end of the trip Khao Lak Explorer has been very helpful, thanks to Theo and his team.
We really appreciated diving with nice equipment, the booties was a great addition, diving 10 times in 3 days would not have been enjoyable with normal fins. The Thai liveaboard boat crew was amazing, super friendly and very attentive to details, sliding your fins on when you are getting ready is just perfect.
Big Thanks to the cook, we did enjoy every meals from breakfast, snack and diner, you never get hungry onboard. I was planning on loosing weight but it will be for another time!
Thanks for the great advices, care and dedication of Khao Lak Explorer liveaboard team for this great scuba diving experience.
