This is one of the best location for newly certified divers who loves coral, under water photographer and generally for all divers. It has thousands of different kinds of fauna, lots of green nudibranch like Kobaryana and Nembrotha where sometimes you can see them actually mating, lots of small caverns on the drop off side that inhabited by hundreds of Red Toothed trigger fish, some grouper, Black Lion fish and lots of annteas that turns the water red occasionally.
On mid water by the drop off side you will see schools of Rainbow runner, Surgeon fish, Red Fusilier and some Gigantic Puffer fish. Sombrero has wide shallow area around the west side and the bottom is composed of hundreds of big boulders of rocks which is coated of many kinds of marine life.
