Fodor's Expert Review Passeggiata delle Mura
On nice days, the citizens of Lucca cycle, jog, stroll, or kick a soccer ball in this green, beautiful, and very large circular park. It's neither inside nor outside the city but rather right atop and around the ring of ramparts that defines Lucca. Sunlight streams through two rows of tall plane trees to dapple the passeggiata delle mura (walk on the walls), which is 4 km (2½ miles) long. Ten bulwarks are topped with lawns, many with picnic tables and some with play equipment for children. Be aware at all times of where the edge is—there are no railings, and the drop to the ground outside the city is a precipitous 40 feet.
