Lake Trasimeno is in the north-western part of Umbria, near the boundary with Tuscany. Lakeshores, which are mainly flat, form bays divided by few promontories. Long stretches of the coasts are covered with beds of reeds, among which we find small beaches. There are three islands: Isola Maggiore, Isola Minore and Isola Polvese. Ferries from Passignano and San Feliciano can lead tourists to Isola Maggiore and Polvese. Isola Maggiore is a singual production centre of laces made by the women of the village, according to the Irish tradition. Important centres are Castiglione del Lago, Passignano sul Trasimeno and Tuoro, with their beaches and buildings.
Lake Trasimeno is part of a Regional Park. Near the village of San Savino we can visit a naturalistic oasis that protects water birds.
