Tevere's fluvial Park
The big River, with its history. In the middle course the hill of Todi. Then: the gorge of Forello, the fortresses Orvietane in Prodo and Titignano. Again, the Lakes of Corbara and Alviano, the latter an essential shelter for the migratory and permanent ornithologic fauna.
Around large and impaired oak and holm oak woods and near the river there are the archaeological remains of Umbrian, Etruscan, and Roman people; castles, or their ruins, which belonged to commanders in the past.
