Worth visiting is an authentic Creole culture destination in Colombia - Providencia Island. Its uniqueness lies in its detachment, geographically being closer to Nicaragua than to Colombia itself. People speak their own English-based Creole language there. No direct air traffic from Colombia is available and flights to Providencia are provided only from San Andres Island. Due to somewhat complicated connection with the continent and consequently lack of mass tourism, Providencia still boasts unspoiled beauty of nature while its villages feature the unique Creole charm and an idyllic atmosphere, described by Ernest Hemingway. Another unique feature of the island is its spectacular annual crab migration when zillions of crabs, forming a living carpet, are moving down the mountain to the sea. And, of course, Providencia takes great pride in its third longest, uninterrupted barrier reef in the world! Diving in turquoise-blue Caribbean waters promises an unforgettable underwater world experience with colorful reefs and amazing fish. Deeper dives at the eastern side of the island promise impressive encounters with larger fish, including sharks. A dive site named Felipe's Place has yet another surprise - a sculpture of Jesus, created by a Mexican artist, submerged 20 m below the sea level!
From the limited number of diving operators, I would suggest Felipe Diving (www.felipediving.com).
