This tour is suitable for very trained bikers. It involves crossing the lake by ferry from Torri del Benaco to Maderno. Once you reach the beautiful town of Gargnano, you begin to climb the most difficult part of the tour, but the panoramic view is incomparable. You reach the lake of Valvestino before crossing the Val di Idro and touching the lake of Idro. A wonderful mountain road takes us to the Ampola lake and then to the Ledro lake. From here, through a tunnel of approx. 3km, we return in view of Lake Garda and along the eastern coast we return to Bardolino. You need a good physical condition, time and desire to discover places that are unknown to many.
