Morning light lifts off Cartagena’s harbor and the sport boat pushes into turquoise lanes, the city shrinking behind colonial roofs. Salt and engine hum mix as guides call out landmarks and the first reef bank appears as a darker green shadow under the water — an invitation to snorkel and to witness a night-sky of ocean light.
