  description: Porto Covo is Alentejo's surf secret—a charming fishing village surrounded by stunning beaches and rocky coves that receive the same Atlantic swells as famous spots to the north but with a fraction of the crowds. The coastline offers multiple options for different conditions, from sheltered coves to exposed beach breaks. The slower pace of Alentejo life, incredible seafood, and uncrowded lineups make Porto Covo increasingly popular with surfers seeking Portugal's quality without the scene.
