A natural sea cave located in the Algarve region of Portugal. The cave is formed by erosion and is characterized by its unique rock formations, arches, and grottos.

Visitors can explore the cave through a series of boardwalks and stairs that offer stunning views of the crystal-clear waters below.

The cave is known for its peaceful ambiance and is a popular spot for swimming, snorkeling, and diving. The natural beauty of the Algar Seco Cave makes it a must-see destination for visitors to the Algarve region.

If you are visiting this place during the summer months, I strongly recommend to go there early in the Morning so you can have place just for you!
