Calipso is the only center that offers a Tayrona Park Safari, where people can spend 2 nights in hammocks on a beautiful beach in the park and dive. The diving is good. They are also pioneering a project to restore coral, which is rapidly degrading worldwide. In conjunction with the C-Force Foundation they are growing coral in a coral nursery. They are the only agency doing this in Colombia and one of the few in the world. You can even take a coral growing/ gardening course. The people are really kind and you can stay at the center before your safari. (note per http://www.calipsodivecenter.com.co/en-us/secpages/voluntariado_EN.php it is a 4-week full-program US$2,000) Calipso is a member of NAUI, the second largest Scuba Diving Association in the World. Any certification between NAUI and PADI is mutually recognizable, but this is NOT a PADI facility according to the PADI website.
