The sun cuts a bright path across the Caribbean as a low-slung sports boat slips away from Cartagena’s docks, engines humming and spray tasting faintly of salt on your lips. Within minutes the shoreline falls back into a ribbon of pastel houses and shipping traffic, and the islands ahead—Isla Grande, Cholón, Agua Azul and Playa Tranquila—begin to gather like scattered coins on the sea.
