During approximately an hour of visit through the “Hondo del Arión”, you can see the 40 units of Millennial Olive trees that form the Millennial Olive Trees of the Arion Natural Museum of Ulldecona. This is the oldest and most extensive set of millenary olive trees throughout the Iberian Peninsula and, probably, the world. At the end of the itinerary you can admire the 8'05 m. perimeter of the “Farha del Arion”. This is one of the two monumental olive trees, declared by the Generalitat de Catalunya, which are on the estate. The visit ends with the tasting of Vilar Millenari oil elaborated and packaged by the Molí de la Creu.
