Barú is a long island on the Caribbean Sea, south of the city of Cartagena. It used to form the tip of a peninsula stretching out from mainland Colombia, before the Canal del Dique was built, cutting off the island. Your first encounter with this island paradise is very likely to be a leisurely boat ride to the beautiful shores of Playa Blanca by the Bay of Cartagena. Apart from the unbelievably crystal clear waters (glass bottom boat cruises and scuba diving come highly recommended), and the white and pink sand beaches, the island is bound by thick mangrove forests. The sea is so clear that it is possible to see a variety of fish and marine life beneath the shallow waters and spot plankton by the beach! Bird watching and water sports like kayaking and snorkeling are understandably popular activities here.
