Move on to one of the Via’s most exciting sections, as the old Via Cassia cuts through a scene of infinite hills dominated by Monte Amiata. Take in the silence at the Romanesque crypt of Basilica del Santo Sepolcro and gaze up at ornate capitals and arches which, according to tradition, protect marble slabs bathed in the blood of Christ.
A first glimpse of Lake Bolsena signals the start of your descent into a volcanic crater, as you roll along dirt tracks through woodlands, meadows and olive groves. In Bolsena, curious Catholics will witness proof of the local 13th-century miracle of 'Corpus Domini' and foodies can sample traditional Sbroscia soup, made from tomatoes and freshly-caught fish from the lake.
