This smallish historical center has displays spanning island history from prehistoric times and Mayan occupation to Columbus' arrival and the beginning of the colonial period. There's also a resident population of some 20 bottlenose dolphins. It's worth checking out the dolphin show held twice daily.

You can sign up for one of several programs; from the Dolphin Beach Encounter where you wade and interact with a single dolphin in waist-deep water to a Dolphin Snorkel or Dolphin Dive, which include interacting with a group of dolphins in the open water.
