Parks and recreation

Located on the northwest side of the village is the Rochester Community Park, erected and operated by the Village of Rochester. The late 1990s saw massive expansion on the park, with the addition of a lighted ballfield, multiple soccer fields, and the Friendship Fort, a massive play-structure built in 1998. The park hosts many village events, including "Sparks In The Park", an annual Independence Day festival with vendors, entertainment, a carnival, and a parade. Spanning three days, the event attracts not only the citizens of Rochester, but visitors from the surrounding areas as well.

Rochester is the southeastern end of the Lost Bridge Trail, a 5.0-mile (8.0 km) trail built by the Illinois Department of Transportation (IDOT) atop an abandoned railbed formerly used by the Baltimore and Ohio (B&O) railroad. It is operated jointly by IDNR and the Village of Rochester. The trail crosses the South Fork of the Sangamon River near Rochester, and crosses Sugar Creek near Springfield. Sugar Creek carries the outflow from Lake Springfield, a sizable nearby reservoir. The Lost Bridge trail name recalls IDOT's failure to prevent salvagors affiliated with the B&O from dismantling the Sugar Creek bridge for scrap.

IDOT future plans include extending the trail to Taylorville, Illinois along the same railroad bed, and this was partly realized in a recent extension from the trail's original end at State Rte. 29 and N. Main St., across Rochester, to just past the intersection of State Rte. 29 and State St.
