Benagil Cave, known locally as Algar de Benagil, is a sea grotto on the coast of Lagoa in Portugal’s Algarve. It should not be confused with Praia de Benagil, the small beach at the fishing village below the cliffs. The beach is a land-based place to arrive at the coast; the cave is a separate cavity reached from the water, subject to maritime rules and sea conditions. That distinction matters before choosing a tour or planning a swim.
Tourism of Portugal describes Benagil as a fishing village whose boats cluster around a small stretch of sand, on a coastline where cut cliffs form caves and sinkholes. The Algar is one of the coast’s best-known natural features, but the official description does not reduce the area to a single photo stop: it is part of a larger limestone shoreline shaped by the sea. The familiar opening in the cave roof gives it a distinctive light, while the water entrance makes access dependent on conditions offshore.
