Located on the outer oceanic slope, they often have a typical relief that could be described as follows: "closest to the surface, where the waves break, a small coral plateau descends a few meters towards the ocean followed by a steeper slope that plunges to -20, -30 or -40m to a second plateau. Plateau which in turn gently descends offshore to a step, clear break that sinks deep into the abyss."

Reefs are generally interesting for their coral structure. On the east coast of the peninsula they are covered with splendid corals in an absolutely unique state of conservation. This is also where we find the famous "fields of roses" made up of corals with specific shapes reminiscent of the petals of these flowers.

The reefs aren't as full of fish as the passes, although they can still hold some nice surprises. But it doesn't matter, that's not why we visit them and after discovering those on the east coast, divers often have the same remark: "Wahoo, it's good to see reefs in such good health" .
