A sea-bright morning in San Pedro sends you out across an electric blue Caribbean; the boat hums, the horizon widens, and two hours later the ocean drops away into a perfect, cavernous dark — the Great Blue Hole. Descend here to 130 ft (40 m) and swim beneath fossilized stalactites, the limestone a record of ancient sea levels and Pleistocene geology that give the sinkhole its dramatic profile.
