From north to south, we'll go down on the west coast of Sardinia. We'll ride with our bikes along a land surface illuminated by the sun and adorned with golden fields, white beaches and variegated shades of blue, and then we will delve into the darkness of its depths. Among caves and mines, we'll reveal the history of a hidden Sardinia and its protagonists in search of priceless treasures: with the passing of the ages, adventurers and explorers eager to discover the natural beauties preserved in the subsoil, leave room for a people forced to dig and face the darkness of the earth in search of one of the most precious energy resources of the industrial age. Are you ready for an unforgettable timeless adventure? Go!
