Islas de Rosario Protected Area is an archipelago national park off the coast of Cartagena, Colombia, renowned for its vibrant coral reefs, crystal-clear waters, and rich marine biodiversity, offering excellent opportunities for snorkeling, diving, and eco-tourism.
The Islas de Rosario Protected Area comprises a group of over 27 coral islands and islets located approximately 20 kilometers southwest of Cartagena, along Colombia's Caribbean coastline. Declared a national natural park, this archipelago serves as a critical marine habitat within the Caribbean Sea, featuring extensive coral reef systems, mangrove forests, seagrass beds, and sandy beaches. The park's ecosystems harbor impressive biodiversity, including colorful coral formations, tropical fish species, sea turtles, dolphins, and numerous bird species. Historically, the islands have been used as fishing zones and have a rich cultural connection to indigenous and Afro-Colombian communities. Today, they serve as a popular eco-tourism destination, particularly for visitors interested in water-based recreation such as snorkeling and scuba diving, where the reef structures offer some of Colombia's best underwater vistas. Key landmarks include Isla Grande, the largest island with eco-hotel accommodations and visitor amenities, and San Martin de Pajarales, known for its crystal-clear waters and vibrant coral gardens. The area is also important for conservation efforts protecting endangered coral species and marine wildlife.
