Boat-access island dive with caves, fish and calm-season windows.
Off São Sebastião, Ilha Montão de Trigo is a boat-access island dive with rocky faces, caves and burrows around the headland. The landing is improvised and sea-state sensitive, so the site works best with a local operator in calmer windows. Expect mixed fish life, a potentially choppy crossing, and conditions that reward flexible timing.
