It was a real treat to gently cycle around the wall of Lucca. Go both ways so you can see things from a different perspective. Even going slowly, you will be done in an hour. The wall and environs are very relaxing and the breeze can break up a hot day.
Warning: We rented bikes from the rental place by the Tourist Information centre at the city gate. It was recommended by Rick Steves. Don't go there - pick one of the newer places instead - the simple black bikes we rented had poor brakes, one had a pedal that kept falling off and were generally in poor repair for bikes that are easy to maintain.
