A beautiful square surrounding a world-famous sanctuary! For cyclists, it's a great place to stop and enjoy a break under the porticoes, shaded from the summer sun!

From Prato Nevoso you can get there by descending the Strada della Penna, after a stretch of about 800 meters that goes up with gradients of up to 18%, a wonderful corner that does not seem to be affected by the proximity to the facilities, from which extraordinary views open up over the valley below.

The first stretch is harder, average 8% for 2.5 km, then the climb becomes easier until San Giacomo. Very beautiful hamlets that you cross, at the roundabout where you turn off for San Giacomo there is also a fountain
