Isla de Providencia lies at the heart of UNESCO’s Seaflower Biosphere, which covers roughly 10 percent of the Caribbean. Among the features protected by the biosphere is Providencia’s coral reef—at 32 kilometers (20 miles) long, one of the largest reefs in the Western Hemisphere. Snorkeling and diving trips to the reef offer opportunities to spot colorful parrot fish, butterfly fish and other species. Snorkelers can also forgo the boat trip to the reef and practice their sport off many of Providencia’s beaches.
