Just 35 kilometers off Cartagena's coast, the Rosario Islands offer pristine Caribbean waters where you can snorkel among colorful coral reefs and tropical fish without straying far from the city. The archipelago's turquoise lagoons and powdery beaches provide the perfect escape for a full day of swimming, sunbathing, and island-hopping with organized tours. Local guides share stories of the islands' maritime history while you float above vibrant underwater gardens that feel worlds away from colonial streets.
