There are now 12 marble runs along the trail between Brione Verzasca and Lavertezzo. No two marble runs are the same. The designs of the marble runs are based on know-how and imagination of many heads. Teachers, graphic artists, designers, tinkerers, etc. helped with this BoBosco (short for “Boccia al Bosco”) project, creating a variety of marble runs that surprise anew every time. “My friends and acquaintances loved my idea, so I got plenty of active assistance with the building of the BoBosco marble runs” says Joe Scolari. For this marble runs large wooden marbles are used, which are on sale for CHF 7 at numerous locations.
