During the guided tour of the Millenary Olive Trees of Arión you will walk among authentic living sculptures. In this place with the highest concentration of millenary olive trees of the world you will be able to contemplate specimens that have resisted the passage of time, especially the Farga I, an olive tree that is more than 1,700 years old and dated as the oldest olive tree in the world still in production. A tasting of original combinations of local products with olive oil and a description of how the oil was produced in the past in Ulldecona, will complement the introduction of the visit in a spectacular mill designed by César Martinell, a disciple of Gaudí, then enjoy a tasting of Millenary and Native Oils of Terres de l’Ebre where you can even buy the oil produced by the owner of the mill and other local products.
