The Benagil sea cave is part of a system of caves that lines Portugal’s southern coast in the Algarve region. A large majority of all visitors to Portugal make a point to visit this Southern region of the country.

Thanks to its 3,300 hours of sunshine every year, more sunny days than almost anywhere around the world, the Algarve is a top winter retreat for people looking to escape Northern Europe’s coldest months and has a longstanding reputation as a top summer destination among European sun-seekers.

In addition, the locals here are always willing to help tourists to get to know more about their way of life and culture.

This most iconic cave is located just around the corner from a beach in the tiny town of Benagil. The cave has layers of sediment in the limestone that has built up over millions of years. It has two big, arch-like entrances and a collapsed roof. Inside is a circular grotto forming a type of miniature, private beach. The Benagil sea cave tour should be on top of your list of things to do in Algarve!

Benagil is a small fishing village, located on the south coast of Algarve, Portugal. The closest city is called Lagoa. The coastline of Algarve is known worldwide for its stunning marine caves and rock formations.

The coast of Algarve is Portugal’s most popular holiday destination, drawing many Europeans looking to embrace the country’s summer sun. Similar to Algarve, the coast close to this cave is made up of Miocene limestone sitting on much older rocks formed in the Age of Reptiles.

How to get to Benagil Sea Cave in Algarve, Portugal?

To visit the caves on the Algarve coast, join a tour in one of the many larger towns including Carvoeiro, Albufeira, Lagos, Portimao, and Faro.

The tours usually last 30 minutes to one hour and cost about €17.50 per person. Another option is to rent a kayak (many marinas or beaches have kayak rentals), commonly the same companies that have the boat tours also rent this equipment. The average price is €20 for a 2 person kayak for 60 minutes.

Another alternative would be to swim your way to the cave. However, it is not the best option nor is it recommended for individuals who have less experience in swimming in the ocean. The water is cold here, so the best way to get used to it is by forcing yourself to completely submerge under the water.


These caves are best visited during low tide – some are even just a swim away from the beach (150 meters). Also, whilst you’re in the water, be extra-careful about the boats around you.
