Spend a full day diving the coral reefs and wrecks of the Rosario Islands from Cartagena. Two guided dives from Isla Grande reveal colorful reefs, turtles and a coastal marine reserve protected for its biodiversity.
More ways to explore the area's outdoor wonders
The boat slips away from Bocagrande and Cartagena's skyline folds into the distance; the Caribbean opens, a wide blue that dares you to lean over the rail. After an hour by boat you hit the Rosario archipelago, where coral gardens and scattered wrecks sit like chapters of the sea floor waiting to be read. Visibility often stretches past 15–25 meters and the currents—when present—push gently along walls and sandy bottoms.
