Latera

It's very easy to visit Latera by foot: the historical centre is almost small and can be walked in about 1 hour. The only disvantage is that Latera is built on some hills, so you'll have to climb up at least one time. Taking a bike would be pleasent to visit the town and also its surrounding and very nice rural landscapes: the only trouble it's the same, climbing up. Avoid car if you're not experienced, you'll risk to remain fit in with your car in very narrow streets with huge medieval walls.
