PuraVida in this JurassicPark like environment

What a special island, and a special feeling to be lucky enough to have been there. Crew was amazing, dives were warm and with good viz, many hammer heads around, eagle and marble rays, dolphins etc... although the best season apparently ranges from August to October, with colder waters and loads of sharks. PuraVida !

Once in a lifetime experience - just amazingly wonderful COCOS ISLAND !

Best diving with hundreds of hammerhead sharks, groups of Galapagos sharks, many white tips, some black tips, eagle and marble rays and an unlimited number of tropical fish. Many different dive sites, some with quite a bit of current. The climb of Cerro Iglesias was also a highlight of my trip to Cocos Island. Okeanos Aggressor II boat was very convenient, great food and an incredibly nice crew.

1. Safety first / 2. Wonderful crew / 3. Great dive sites
