Witu Islands is a very pretty island group which offers a lot of variety in diving. The islands are of volcanic origin. Garove Island (about 60 km northwest of Kimbe Bay) was a large volcano in the past. The crater is now flooded with water (approx. 300 meters deep) and makes for some great diving around the island that was created within the volcano's caldera. The landscape is awesome! There are nutrient rich currents in the area, so marine life is very diverse. At dive sites like "Lama Shoals" tourists are in for big fish like barracudas, trevally, large dogtooth tuna, Spanish mackerel, and sharks. The reefs here are grown over by gorgonian fans, black corals, different species of soft corals and hydroids. They also get "muck diving" around the Witu islands. The so-called "muck diving" is done in areas with sand and rubble bottom, where you find all sorts of weird but wonderful creatures.
