Grosio is an important historic town a few kilometres from Tirano, going towards the northeast part of the valley. You can’t leave Grosio without visiting Villa Visconti Venosta, home of the noble family dating back to the late 1600s. Another major attraction is the exciting Rock Engraving Park of Grosio, with Rupe Magna, the largest engraved rock in the Alps, with over 5000 engravings. The Park also houses the Castle of S. Faustino and the New Castle (Castello Nuovo). From Grosio, you can easily explore the beautiful Val Grosina natural park.
