Morning light slides over the harbor and a low-slung boat slips through a maze of prop roots as mangrove leaves brush the water—this is the opening act of a day spent between two distinct coastal ecosystems. The guide cuts the engine for a soft glide through Estero’s mangroves; the trees seem to lean in, their roots cataloguing tides and small fish. Later the boat crosses to Cayo Arena (La Isleta), a white-sand sandbank ringed by shallow turquoise and a living coral fringe that draws snorkelers like a magnet.
