Firebreak of about 5km that from Monte Bignone descends towards Verezzo. Terrain mostly made up of slabs, stones and sand, with several steps. Some sections (about 3/5 of the route) are too demanding for a gravel stock (at least for me), you have to push, better to do it with a full mtb. Along the route it is possible to take various downhill routes. I recommend doing it downhill, but if you want it is also possible uphill.
