Benagil Cave
Faro
Benagil Cave, located near the small hamlet of Benagil in the Algarve region of Portugal, is a remarkable natural sea cave famous for its distinctive geological formation. Unlike other sea caves along the Algarve coastline, it has been eroded both from the side and from above, creating a large circular opening in the ceiling that allows sunlight to illuminate the interior and its small hidden beach. This natural skylight creates a spectacular visual effect, making it a popular destination for tourists and photographers. The cave is accessible only by watercraft, such as kayak or boat tours, and is part of the coastal municipality of Lagoa, a region that has transitioned from a fishing economy to a vibrant tourist area. Due to concerns about overtourism and safety, regulations have been introduced since 2023 to limit the number of visitors and restrict access to authorized tours only, preserving the site's natural beauty and ensuring visitor safety. The surrounding area also features the Praia de Benagil beach and is close to other renowned beaches like Marinha Beach, making it a highlight of Algarve's scenic coastline.
