The three lakes of Lake Trasimeno, Lake Bolsena and Lake Corbara are really worth a visit and are great for watersports. From Castiglione del Lago you can take a boat trip to the two little islands of Isola Maggiore and Isola Minore. Not far away is also the thermal spa of San Casciano dei Bagni.
A little further away, about a two-hour journey, you can go rafting on the river Corno, near to Norcia. Not far from Terni are the amazing waterfalls of Marmore (‘Cascate delle Marmore’). Trips can also be arranged to the Tane del Diavolo (‘the Parrano gorges’). These have natural ravines created by the river, with walls reaching up to 60-70 metres. Adventurous people may also like to visit the caves with a special guide.
