El Faro de Barbaria (or Far de Cap de Barbaria) is one of the most representative icons of Formentera, located in the southwestern end of the island. It was inaugurated in 1971 (although planned since 1924) and measures about 17 meters in height. It stands on an impressive vertical cliff about 100 meters above sea level. Due to high visitor numbers, access by car or scooter is restricted during high season. You must leave your vehicle in a nearby parking lot and take a walk (about 15-20 minutes) along a narrow road that offers spectacular views. It is worth continuing the walk to Torre des Garroveret.
