A reef on the east side of Porto Santo, described as an easy dive with depths between 8 m on top of the reef and 22 m on the sand. The shallowest part is dense with small fish, Turkish wrasse and damselfish above all, while deeper down there are several species of bream, octopuses, morays and rays.

The dive
The reef lies on the east side of the island and the profile is simple: 8 m on top of the reef, 22 m where the rock meets the sand, and an easy dive between the two. A group can be worked down the slope and brought back up onto the reef top without any part of it feeling like a deep dive, so the depth range is a matter of choice rather than of planning.
The shallowest part is the busiest — the catalogue calls it an authentic small fish pond, thick with Turkish wrasse and damselfish, and it is the part worth saving time for at the end. Deeper, on the edge and the sand, the mix changes to several species of bream, octopuses, morays and rays, which is the more patient half of the dive and the one that rewards looking under and into the rock rather than over it.
