Choose between one of the two routes from Brione V. to Lavertezzo or from Gerra V. to Sonogno and walk through nature with a wooden boccia ball in the constant company of the river. During the walk, let the ball run through the different courses, where it is carried by pulleys, cable cars or slingshots. A total of 23 lanes await you spread over the two trails, with each trail taking about 4 to 5 hours to complete. For small children, the Gerra-Sonogno route is a little more suitable, although an adult supervisor is always required for children. You can reach the route Brione Verzasca-Lavertezzo through four accesses: Brione Verzasca Piee, Brione Verzasca Ganne, Brione Verzasca Motta and Lavertezzo, with the first section being the most demanding. The Gerra Verzasca-Sonogno stretch also has four accesses: Gerra Verzasca al Ponte, Frasco Campagne, Frasco Chiesa and Sonogno, although here all sections are rather flat. Nevertheless, both sections are not suitable for strollers. Along your way from Sonogno to Lavertezzo you will find several picnic tables. Some of them have small grills, but there is no stored wood. You may have to collect it yourself in the woods. Be sure to check and respect the local fire bans!
