Cala Arenas is a scenic beach in Algeciras, Spain, located at the southern end of the Bay of Gibraltar and overlooking the Strait of Gibraltar. It's known for its three small coves and pebbly shores, offering a more secluded and natural beach experience.
The beach is part of the El Estrecho Natural Park, ensuring its surroundings remain largely undisturbed, with the nearby coastal community of Getares being the closest settlement.
Historically, Cala Arenas has been an important site due to its strategic location, hosting a Phoenician port and various defensive structures like the Recinto del Cerro de la Horca and Torre del Fraile.
