Mario's Reef or El Cien as its name says it is a reef that has 100 ft deep, is a rock bar about 800 meters long and about 25 meters wide. 

 

This site corals are virtually absent, this little depth and light penetration, although it is possible to see some sea fans and invertebrates, as fish no large schools as elsewhere observed pulmo Cape but the lack of abundance is offset by the size of the few who are, such as big snappers, jacks, strong fish, and if you are lucky some tuna or a bull shark or cat in the shadows. 

 

Undoubtedly a very good dive spot in pulmo out but unfortunately only for experienced divers.
