Portugal’s coastline is known for cliffs, clear water, and long sandy stretches. What makes it stand out even more are the caves carved directly into the shoreline.

Some of the famous Portugal caves beach spots you must know are:
The most well known Portugal caves beach sits just offshore from the village of Benagil in the Algarve. Algar de Benagil is a massive dome shaped cave with a circular opening in its ceiling. Sunlight enters through that opening and reflects off the sand and water below.
There is a small beach inside the cave, which is why it is often described as a cave beach Portugal landmark. You cannot walk into the cave from land. Access is by kayak, paddleboard, or licensed boat tour only. Swimming is discouraged and often restricted due to safety concerns.
This Portugal cave beach is best visited early in the morning when tour traffic is lighter and the light is softer.
Located along the Algarve coast, Praia da Marinha is famous for its cliff formations and clear water. What many visitors miss are the nearby caves that sit just beyond the beach.
Kayaking from Praia da Marinha allows you to reach several beach caves in Portugal that open directly into the sea. Some are large enough to paddle into, while others create arches and tunnels along the cliff face. This area is ideal if you want both a classic beach and a Portugal beach cave experience in the same day.
Ponta da Piedade is not known for a single cave beach but for a network of grottos, arches, and narrow passages. Boat tours and kayaks move through towering rock walls that have been shaped into caves over time.
While not every cave here has a sandy floor, this area is still one of the best places to see dramatic Portugal caves beach scenery. The water color shifts between green and blue depending on the light, making it popular with photographers.
Captain’s Cave, also called Gruta do Capitão, is another Algarve formation often included in guided tours. It does not attract the same crowds as Benagil, which makes it appealing for visitors who want a quieter cave beach in Portugal experience.
Boat tours usually combine this cave with several nearby formations, giving you a broader look at beach caves in Portugal without focusing on just one stop.
