The Olhahli Caves are the northern tip of the North Male Atoll - on the north Reetha Rah. There are a couple of small caves at 15 and 20 metres but the main attraction is a big cave 40 metres long at a depth of 25 metres. In the big cave on the ceiling are blue and white soft corals, as well as some sea fans and sponges. At its base is a mixture of sand and coral on which seawhips grow. The reef also hosts moray eels, stingrays, turtles and puffer fish. Napoleons, white tip sharks and eagle rays are often seen out in the free water.
