Las Terrenas sits on the Atlantic north coast of the Dominican Republic and draws divers with an unusually varied mix of site types. Reefs, canyons, caverns, walls, and wrecks are all within boat range, covering a depth band shallow enough for beginners at Cinco Metros and Canyons through to the wreck of the Dolphin, which suits intermediate divers. Visibility typically runs to around fifteen metres, and water stays warm throughout the year, peaking in late summer. The calmer window runs from May to September; conditions between October and April can become more unsettled. Sites containing cavern sections should be treated as guided overhead environments rather than open swim-throughs.
