Boat logistics and marine-park procedures are easiest with a local operator from Sesimbra.
Pedra das Ancoras is a boat dive off Sesimbra built around low rocky ridges, a cluster of lost anchors, and plenty of small-life details in the cracks and ledges. It is a straightforward protected-site outing for relaxed scuba divers, with room to slow down over the rocks and watch for fish, cephalopods, and sponges on every pass.
