On a sunny day the people of Mantua head for the waterfront, where grassy banks throng with fishermen and picnicking families. Each of the three lakes has a distinct style. The shore of Lake Mezzo, complete with the child-friendly gadgets of the Parco dell Scienza (outdoor science park), is the most crowded; the quieter path beside Lake Superiore meanders amid reed beds and wading birds; while the shore of Lake Inferiore brings broad views.
