You just cannot loose your way: "Brennero" highway A22 direction Lake Garda. When arriving from the north you exit at "Rovereto sud - Lago di Garda nord", driving across Mori, Nago, Torbole to Malcesine. When coming from south, you may exit at "Affi - Lago di Garda sud", and drive your way through Garda, Torri del Benaco, Brenzone to Malcesine.
Right at the heart of Malcesine follow the sign that takes you to "Funivia Monte Baldo" (trolley), then driving further about 1 km until you reach the cross-road that takes you up to the "Panoramic Street". Now you sit back and enjoy the 5 km ride that brings you to the highest point - which is your destination "Querceto"
