Sentiero 4 - Anello delle Carbonaie

Roundtrip part of Francigena Mare with connection to "Sentiero 3 - Anello delle due Vie", passing through the thermal spring "I Bollori".

This 5.7 km route sits in the sweet spot for a half-day outing — long enough to feel rewarding, short enough to leave the afternoon free. Expect around 1 hour and 16 minutes.

Laid out as a circular walk, this trail finishes exactly where it begins — no need to arrange transport back or retrace your steps. Follow the 4 waymarkers throughout to stay on the official trail line.

As a Local Walking Network (LWN) route, this trail has a strong community character. It serves both regular local walkers and visitors discovering the area for the first time.
