Just off the coast of Cartagena, Colombia lies a tropical archipelago that captures the essence of Caribbean perfection — the Rosario Islands (Islas del Rosario). Consisting of 27 idyllic islands surrounded by turquoise waters and vibrant coral reefs, this marine sanctuary is a natural wonderland where white-sand beaches, mangroves, and clear lagoons coexist harmoniously. Whether you visit for a day trip or stay overnight, the Rosario Islands promise a tranquil escape filled with stunning marine life, exhilarating water sports, and an authentic taste of Colombian coastal beauty.
History of Rosario Islands
The Rosario Islands’ history is intertwined with that of Cartagena de Indias, Colombia’s colonial port city. These islands were once inhabited by indigenous Karib people, who relied on fishing and small-scale trade. When the Spanish arrived in the 16th century, they marveled at the area’s beauty and used the nearby coral formations to protect Cartagena’s harbor.
By the 19th century, wealthy families from Cartagena built holiday homes across the islands, transforming them into exclusive retreats. Recognizing the ecological significance of the coral ecosystems, the Colombian government created the Corales del Rosario and San Bernardo National Natural Park in 1977 to preserve its reefs, seagrass beds, and mangroves. Today, more than 19,500 hectares of land and sea are protected, offering refuge to hundreds of marine species including tropical fish, sea turtles, starfish, and nurse sharks.
