At the Tug Boat Beach, near a big jetty (Dock) and industrial garbage, the Coral Restoration Foundation Curacao maintains coral supporting trees. These trees hold coral fragments, providing them with perfect growing conditions. The Foundation helps rebuilding reefs by outplanting clusters of corals on structures all along the coast of Curacao. The corals will in time overgrow their structure and form a new, independent coral colony to house many types of fish and marine species.
Diving and snorkeling is not so easy on the Cape Verdian Islands. You have to overcome vicious shore breaks and currents. Wet suits are recommended.
Underwater, however, you may enjoy coral reefs, 639 species of fish including Mantas, sharks and turtles. (Which we did not see, unluckily). More Information: Stewart, Murray. Cape Verde (Bradt Travel Guides)
