Great

The dives were fantastic, and the guides were very knowledgeable and helpful. The crew was always ready to help and very friendly. The food was great, as was the atmosphere on the boat, which made for a great time between dives. All in all, it was a very positive experience.

Amazing experience

Loved everything about it. Wonderful crews (special thanks to Audrey - having a crew member who spoke Korean was a huge help for us!) and the chill vibe made the dives more enjoyable. And good food was also a big big plus ;) And of course wildlife of Similan Islands was epic!
