The kilometres shown refer to the route from Acquaviva di Nerola to Ponticelli di Scandriglia. This variant, although it lengthens the route, allows you to visit the Farfa Abbey, one of the most important Benedictine monasteries in Italy.
The route from Monterotondo to Acquaviva di Nerola coincides with the main itinerary of the Monterotondo–Ponticelli di Scandriglia stage.
From Acquaviva - a hamlet of Nerola - look out for the turn-off to Farfa Abbey. A gradual climb leads to the outskirts of Fara in Sabina. The route continues downhill to Farfa Abbey (18.8 km from Acquaviva di Nerola), which is a good place to take a break.
A visit to this beautiful abbey is highly recommended.
The alternative route continues through the town of Toffia.
At the turn-off for Ponticelli, you can decide whether to head back south and stop at Ponticelli (21.2 km from Farfa Abbey) or continue on towards Poggio Moiano (23 km from Farfa Abbey).
