As good as indonesia on some dive sites

some sites had several schools of different kinds of fish, as well as sharks and turtles, all in one dive. I like to watch schools of fish. I have been to Indonesia on many dive vacations and Cano Island is as good as Indonesia for schooling fish on some dive sites.

Enchanting island teeming with under the sea life...amazing!

Seeing a Manta Ray, hammerheads, marble rays, spotted eagle rays, a Galapagos shark and the whale shark on Easter morning first dive of the day with dolphins playing in the water when we boarded the panga. Yes, all of this on one dive...spectacular!

Trip of a lifetime

The diving exceeded expectations, the crew was so hospitable and went out of their way to make sure we lacked for nothing, and the food was the best I've ever had on a liveaboard. The only criticism, is that the boat's common areas could use a little updating.
