No special access issues
Exit the main road right at the south exit of the Galleria Bianchi tunnel (Passo Gottardo - Direction Airolo). Drive up the road for 800m until a big parking lot. Do not drive further at any time. Hike the flat gravel road direction east until you can see the building of Rosso di Fuori. Pass this building on the right to see the first boulders.
The building ist used by the alpine herdsmen during some weeks in summer. Please behave respectfully and close all gates and fences.
