The Fluvial Park of Lastra a Signa lies north of the town. It extends along the River Arno, through the ward of Stagno. The park covers 19 hectares and is divided into two sections. One was inaugurated in May 2002, and the second is being completed.
There are walkways, a cycling path and a riding trail for people who enjoy jogging, cycling, horse riding or simply going for a stroll. The Teatro Naturale, situated inside the park, hosts musical performances, as well as sports and social events. It was constructed taking advantage of the natural shape of the land.
