The gentle sloping reefs of the north coast of Penida provide beautiful coral reefs starting at just 2 meters underwater and cover the slope all the way to the bottom. These mixing hard and soft corals, provide homes to many small critters like; nudibranch, crabs and shrimps while also providing a healthy living environment for many schooling reef fish. Off the reef and cruising in the blue water, it is possible to see the large fish like Giant Trevally, Turtles, Napoleon wrasse and Barracuda.

The large plateaus of the south provide the cleaning and feeding stations for the Manta Rays and this where the two manta dive sites are located. Although not as rich in coral diversity as the north, the plateaus do offer divers interesting rock formations covered in sponge and coral. The high light of the southern dive sites, is having the chance to see the Manta feeding in the shallows or being cleaned by the reef fish.
