We haven't seen much on this forum about Monte Subasio - the mountain that looms above Assisi. Taxis can take you to the Eremo della Carceri which is the church, monestary and hiking trails where St. Francis used to go to pray.
But we took the car up to the top. The road goes up farther than the Eremo where you get a marvelous view of the Umbrian valley. Then we drove the road over the mountain to Spello.
I recommend this drive. We saw herds of sheep, horses with long hair and herds of cows wearing big bells around their necks, hang gliders floating down from the edges. Beautiful.
