With its variety of species, from smallest animals up to big fish (like angel sharks or Atlantic rays) and marvelous colourful plant species it ensures diverse and interesting things to see for everybody.
Typical for Lanzarote are also the numerous rock formations under the surface, which sometimes look man-made. Formed by solidified lava there are many caves, tunnels, canyons etc. which let each dive become a special one.
