Cascais

Cascais sits on the central Portuguese coast near Lisbon, with easy access to a variety of diving in temperate Atlantic waters. The area offers shore and boat diving from the town and nearby beaches, featuring rocky reefs, coastal caverns, and some wrecks accessible to recreational divers. Expect visibility that can be good but variable with currents, and water temperatures that range from cool to mild depending on the season. Marine life includes wrasse, bream, octopus, and common invertebrates, with chances to see stingrays and small pelagic activity when conditions permit. The region is well-suited for local dives, weekend trips from Lisbon, and drift dives along the nearshore shelves.
