Praia da Marinha is a beach in the Algarve, the southernmost Portuguese province. It belongs to the administrative area of Lagoa and is located in the so-called "Rock Algarve". Many holidaymakers from the nearby resort of Carvoeiro, about 5 km away, use the beach for swimming, diving and snorkeling. There is a free car park here (but you should get there early!). It is the starting point for the coastal hike to Benagil.

The small village south of Lagoa seems to cling to the cliffs surrounding the curved bay. The light blue water on the beach sparkles. The Benagil Cave, also known as the Cathedral by the locals, is a small demonstration of the strength of the waves that regularly hit the rocky coast of southern Portugal.

This secluded bay is not only beautiful but also has historical significance. It used to be a hiding place for smugglers bringing goods from ships to shore. Today it is a popular yet quiet spot for tourists who want to explore the scenic coastline.

The most famous sea cave in the region is undoubtedly the Benagil Caves, known for its unique skylight and hidden sandy beach. Other notable formations often included in boat tours are Zorreira Cave and the Arcos de Marinha.

Yes, the Gruta de Ibn'Ammar, located within the Union of Parishes of Estômbar and Parchal, holds significant archaeological vestiges of human occupation from the Middle Paleolithic to the medieval period. However, this cave is not open to the public due to the presence of protected bat species and for security reasons.
The caves are renowned for their stunning geological formations. You can expect to see natural skylights, like the famous 'eye' of Benagil Caves, impressive rock arches, hidden sandy beaches, and vibrant blue-green waters illuminated by sunlight. Formations like the Algar Seco Rock Formations also feature unique sea-carved windows and grottoes.
