Ataúro is geologically diverse with overhanging cliffs, stepped terrace formations, limestone caves, rock fossils, and even freshwater and small hot water springs.
The island is very rugged with a high mountain spine stretching from the south and gradually diminishing in the north. Ataúro is incredibly dry with little water run-off and this contributes to the amazing reefs and sea water clarity.
Cave of Our Lady Mary
The Cave of Our Lady Mary is a man-made religious structure erected by the Protestant and Catholic believers of the island.
