Fodor's Expert Review Lakeside Lido

This waterside promenade below the pretty town is lined with restaurants, ice-cream parlors, and cafés and is a favorite spot for Roman families to relax on summer days. No motorized craft are allowed on the lake, but you can rent paddleboats and kayaks. In summer, you can also take a short guided boat trip to learn about the geology and history of the lake, which lies at the bottom of an extinct volcanic crater. The deep sapphire waters are full of swans, herons, and other birds, and there is a nature trail along the wooded end of the shore for those who want to get away from the crowds.

Deck chairs are available for rent on the small beach, and you can stop for a plate of freshly prepared pasta or a gigantic Roman sandwich at one of the little snack bars under the oak and alder trees. There's also a small permanent fairground for children, and local vendors often set up temporary shops selling crafts, toys, and snacks on the warmer weekends.
