Blocks, caves and furrows in the south face that took ships' anchors

A plateau-shaped rock a third of a nautical mile north of Cabo de Palos harbour, rising to 8 m and dropping to 22 m, bordered by posidonia meadow. Its southern face is a route of blocks, caves and furrows that took the anchors of ships passing the cape, and corvina, barracuda, sea bream and large groupers work the rock.

The dive
The bajo lies barely a third of a nautical mile off the harbour, so the run out is short and the descent begins almost as soon as the boat settles. You drop onto a rock formation shaped like a plateau, though it is far from flat: the top is full of irregularities from about 8 m down, and the whole rise is bordered by posidonia meadow that marks the line where rock gives way to sand.
On the west side a slope runs off the plateau and joins the cape itself, which is the natural direction to start. Following the perimeter round to the south brings you to a second rock formation standing off the main mass, and this southern edge is the part local guides rate highest: a route of blocks, caves and furrows carved as if by an imaginary river. The site bottoms out at 22 m.
The southern face is also where the site earned its reputation among local divers: the rock caught and kept the anchors of ships passing the cape in earlier centuries, and they are still there to be picked out among the furrows. The bajo is not large — it can be covered in one or two dives — so there is time to work back along the rock, where corvina, barracuda, sea bream and large groupers are the fish to expect.
Background
The southern face of the bajo has yielded anchors lost by ships in earlier centuries, snagged on the rock as vessels worked their way past Cabo de Palos. Local operators send divers along that face to look for them, among the blocks, caves and furrows cut into the southern edge of the plateau. The bajo sits inside the Islas Hormigas marine reserve, protected since 1995.
