The reef system surrounding the island of Bonaire is protected as part of the Bonaire National Marine Park and boasts the greatest diversity of fish species in the entire Atlantic/Caribbean with well over 300 different species. Conservation efforts to maintain the health of the island's reef system has made Bonaire one of the world's top destinations for scuba divers.

Bonaire's success at protecting the health of its reef system has become a model around the world.
