Top notch in every aspect!
The diving was incredible- hammers on every dive (and whitetips, blacktips, Galapagos, silvertips), lots of rays, schools of jacks/snapper/grunts, frog fish, flounder, lobster, and hundreds of other types of fish. Swimming under waterfalls our playing soccer on the beach between dives...all in paradise. I can't wait to go back!

magical diving in Cocos island
My reason to go to Cocos island was to see sharks. I saw a lot of them, mainly hammerhead sharks, whittip sharks and some tiger sharks. The hole experience was amazing. Thanks to the chef who prepared delicious food every day.
