The Cabo de Palos Lighthouse is an impressive local landmark. It stands on a rocky headland on the Mediterranean coast, close to the town of Cabo de Palos and near the popular holiday region of La Manga del Mar Menor. The lighthouse is visible from afar and attracts many visitors. The lighthouse was commissioned in 1865 and stands on a site that has been used by sailors for centuries. In ancient times there was a watchtower there to monitor the coast. The lighthouse itself is not open to the public, but it is possible to drive up to the top and visit the outside area. From there you have spectacular views over the rocky coastline and the sparkling Mediterranean Sea.
