Praia Dona Ana is a popular beach located in Lagos, a town in the western Algarve region of Portugal. It is known for its clear, turquoise waters, golden sand, and striking rock formations that surround the beach. The beach is sheltered by high cliffs and is accessible via a long staircase that leads down from the top of the cliffs.

Praia Dona Ana is relatively small, with a length of about 300 meters. Despite its size, it can get quite crowded in the summer months, as it is one of the most popular beaches in the region. The beach has lifeguards on duty during the summer season, and there are several beachfront bars and restaurants where visitors can enjoy a meal or a drink.

One of the most notable features of Praia Dona Ana is the rock formations that rise from the sea, forming small coves and arches. These rock formations make the beach a popular spot for snorkeling and diving. The beach is also a popular destination for photographers and Instagrammers, who come to capture the stunning scenery and sunsets.
