Pedra das Âncoras

Low rock with lost anchors on the bottom at 15–18 m

Area photo: YukioSanjo · CC BY-SA 4.0

Low rock formations with a lot of relief for their height, averaging 15 m and reaching 18 m at the deepest. The name comes from the anchors lost among them, still lying on the bottom. Bream, rockfish, cuttlefish, octopus and mullet work the rock, and coloured sponges cover the faces.

The dive

The formations here are not tall, but the relief between them is what makes the dive: cuts, ledges and low walls at an average of 15 m, dropping to 18 m at the deepest. Shallow ground on this coast means the longest dives available, so the site is worked slowly rather than covered, and the interest is in looking into the rock rather than swimming over it.

Anchors lost here lie among the formations and give the site its name — how old they are, or where they came from, is not recorded. The usual residents are on the rock alongside them: bream and rockfish over the tops, cuttlefish and octopus in the gaps, mullet moving through, and coloured sponges on the stone itself.
