Umbria is fantastic. The land, the friendly people, the cities and the vilages, the food and the wine. It was much more than I expected.
But it is not bike friendly. In many places, especialy in the Apenine mountains, the only road is a highway forbitten for bikes. There are lovely roads for cycling but not connected.
An evening when I stopped at the end of the road, a car stopped beside me and a friendly man show me a path throw the mountain. In another occasion where I coundn't find my way on multiple crossroads, I asked for information in a cafe and someone took me and my bike on his van for about 3 km, because as he told me, it was very difficult for him to explain.
On my way back, I found that it is better to take a local train to pass the difficult places.
