The Territorio S\u00e9nia is home to the world’s largest concentration of ancient olive trees. A mosaic of trees and dry stone, known as the sea of olive trees. In Tarragona, an open-air museum has been set up in Ulldecona. There are also some cycling and walking trails, working oil mills, guided tours and olive oil sales and tastings. It is an hour’s drive from the city of Tarragona, but near the Ebro and therefore easy to combine. See link to more info below.<\/p>\n\n\n\n
