Good food and big schools of fishes

Koh bon, koh tachai, Richelieu rock are so nice. Many big schools of fishes make it memorable. Briefing is effective with introduction of sites and marine lives. Food is really good. Thai crew are nice. Better to have good buoyancy control because some sites have rocks and narrow passages.

Three of the best days in my life

As an rather unexperienced diver it felt really awesome how the diveguide were adjusting to your level, and it wasn’t like we were missing out on anything, we still got to see manta, a LOT of different kinds of morays and fish and slugs and all you could ever dream of. My logbook didn’t have room for all the awesome creatures we identified together. Next time I will definately go for the full five days.

Good first liveaboard

This was my first live aboard, so I didn’t quite know what to expect. 4 dives a day was a bit much, but the dive spots were nice, especially the dives in Richelieu Rock were amazing, and makes it worth doing a longer cruise. The crew and guides were very helpful, and made effort to accommodate different needs and levels of diving. The cabins were quite basic, but adequate compared to the price.
