Beginner-friendly rock dive off Leixoes with small Atlantic life and a wreck.
Olo is a compact rock dive off the Port of Leixoes in Matosinhos. It works well as a relaxed boat dive when conditions are calm, with hard structure that attracts anemones, sponges, crustaceans, molluscs, and small fish. A nearby wooden wreck adds a second point of interest for divers who want a short bonus stop. Plan on boat logistics, calm-weather windows, and good buoyancy around the rock and any adjacent structure.
