Following this path, just before reaching the devil's well, it is not clear where to go, the path disappears and also the white and red signs. We had to go a bit by intuition and take a very steep climb in the woods to get there. Once we reach the well, the path continues easily until the end.

Please note: The end of the Sentiero dei Mulini is closed off with a gate, so you cannot continue walking to Bomarzo or Mugnano in Teverina (which was our original intention), but you must return to the starting point via the same path.

Walking along via S. Egidio, you will find the beginning of this short but very suggestive path inside a "via cava" (roads dug through the tuff that connected the bottom of the valley with the territories above and, in other areas, were also used to drain excess water from agricultural land). This via cava is full of caves dug directly into the tuff, probably used as stables or cellars to store wine or food.

Please don't enter into the cavity "Pozzo del Diavolo". It's a shelter for bats and people inside could create noise that disturbes colonies. It is also dangerous to enter: we must report several accidents occourred in this point.
