Gradisca-Rocca-Cima Pietrarossa e single tracks monte San Michele

Start and finish from the car park of the Al Ponte restaurant in Gradisca. The route winds along karst trails and single tracks to reach the Rocca di Monfalcone, the World War I trenches at Cima Pietrarossa (elevation 121), then returns via Lake Doberdò through the Brestovec cannon galleries and then climbs Monte San Michele from which you descend through two very technical and challenging single tracks. The route is suitable for everyone in the first part, becoming demanding both technically and physically in the second part after reaching the Brestovec galleries.
