The passage through the suggestive Cavoni to Nepi requires a bit of practice in carrying the bike on your shoulder. Perhaps with electric MTBs it is more difficult given the weight. To be avoided in rainy periods because you could slip. Once you have crossed the bridge at the end of the descent, DO NOT follow the path that runs parallel to the stream; instead you need to follow the path that goes up to the right. The Cavoni begin immediately after, about ten meters ahead, even if you can't see them from the bridge and the start of the path. The first 20 meter long section will be done with the bike on your shoulder, then at the crossroads you will go left where the path widens and in some sections you can even cycle.
Very suggestive passage with sections 1 meter wide and rock walls up to 20m high.
