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!

Amazing food, dives and people

We loved the diving (loads of fish, BIG rays, guitar sharks). Dive master went out of his way to make the best of every dive, especially on days with not all too perfect weather conditions. Crew is really attentive, both under water as on board the ship. We had a good laugh with the boat boys. The chef deserves a special shout out, for her mouth watering dishes were the best we ever had on board!
