Islas del Rosario, Cartagena’s coral islands and marine park

Islas del Rosario, officially known as the Archipiélago de Nuestra Señora del Rosario, is a group of small coral islands off the Caribbean coast of Colombia, lying off the insular zone of Cartagena de Indias in the department of Bolívar. The archipelago forms part of a wider marine protected area that brings together coral reefs, mangroves and shallow lagoons in a single seascape.

A coral archipelago off Cartagena

Islas del Rosario is a coral archipelago located off the coast south-west of Cartagena, within the Caribbean Sea and the wider insular zone administered by the city. The islands are described as a cluster of small coral formations that sit on a shallow submarine platform off the Barú Peninsula and the mainland coast.coral archipelago located off the coast The terrestrial area of the archipelago covers a modest land surface compared with the much larger area of sea and reef around it.

Descriptions of Islas del Rosario in Spanish and English sources converge on a picture of a compact group of coral islands off Cartagena, with figures for the number of islands centring around a few dozen. One widely cited description gives a terrestrial area of about 20 hectares spread across the islands, with the surrounding shallow platform and reefs expanding the effective footprint far beyond the emergent land.terrestrial area of about 20 hectares Seen from above, the archipelago appears as low-lying coral cays ringed by shallow water, set against the darker tones of deeper sea.

Within Colombia’s network of national natural parks

Islas del Rosario forms part of the Parque Nacional Natural Corales del Rosario y San Bernardo, a national natural park within Colombia’s protected-area system that focuses on marine and coastal ecosystems.Parque Nacional Natural Corales del Rosario y San Bernardo The park covers both the Rosario archipelago and the San Bernardo Islands further along the coast, together with sections of the surrounding reef platform and adjacent sea.

The Rosario and San Bernardo Corals National Natural Park was created in the late twentieth century, with 1988 given as the founding year in several descriptions, to safeguard one of the most significant coral reef systems along the Colombian Caribbean coast.Rosario and San Bernardo Corals National Natural Park Protected-area descriptions refer to an extent of about 120,000 hectares when the combined marine and insular zones of Corales del Rosario y San Bernardo are taken together, from the highest tide line on the islands down across the reef slopes to a defined depth contour.extent of about 120,000 hectares Within that area, Islas del Rosario accounts for a portion of the emergent land and surrounding reefs, sitting under the wider umbrella of the national park.

Reefs, mangroves and shallow Caribbean waters

The defining feature of Islas del Rosario is the combination of coral reefs, clear Caribbean water and coastal vegetation assembled in a relatively compact area. The archipelago lies within a belt of reef that supports hard corals, sponges and reef fish, with the shallow platform around the islands providing habitat for seagrass beds and mangrove stands.the coral reefs around Islas del Rosario Descriptions of the national park list dozens of coral species and many more species of fish and invertebrates within the wider protected area.

Colombia’s national tourism information frames Islas del Rosario and the neighbouring San Bernardo archipelago as an area where coral, mangroves and seagrass coexist, creating a patchwork of shallow channels, lagoons and reef slopes.Rosario Islands and San Bernardo In and around the archipelago, low coral cays rise only a few metres above sea level, while mangrove roots bind the edges of some islands and seagrass meadows spread across the quieter, sandier shallows. The interplay of reefs, vegetation and open water gives Islas del Rosario a character distinct from the walled streets and stone ramparts of Cartagena on the mainland.
