About Benagil Cave

Benagil Cave, carved naturally into the limestone cliffs of the Algarve coastline, is famous for its open dome-shaped ceiling, which allows sunlight to pour down onto a small sandy beach within the cave, creating one of the most photographed natural sights in Portugal. Accessible only by water, the cave can be reached by boat tour, kayak, paddleboard or a short swim from the nearby village beach in calm conditions.

The cave sits close to the small fishing village of Benagil, itself a charming base for exploring the surrounding coastline's other sea caves and rock arches. Due to the cave's small size and popularity, visitor numbers are often informally managed to avoid overcrowding, particularly during the busy summer months, so arriving earlier in the day generally offers a quieter experience.
