When we got back, Valeria had researched details of campsites beside Lago di Bolsena. We caught the 3.30pm bus to Acquapendente.
After a brief stop there, we decided to walk on and find somewhere to camp along the way. We called in at a tourist information centre and collected a map of the Francigena route to Bolsena. A very helpful young lady who spoke a little English was keen to assist. We then left the town, following Francigena signs which soon petered out. We headed towards the main road and after a while were offered a lift by our TIC girl and she took us all the way to Lago di Bolsena where she dropped us at a campsite on the western side. We had a 40 minute wait for the proprietor to return but it was very pleasant by the lake side.
We were the only campers on the La Grata site and spent a very peaceful night.
