Trails wind through the natural areas and offer an up-close look at many unusual natural areas and plants.  The Lyon-Richard Young trail system is close to 3 miles in length.

Lyon Forest Preserve is located on Van Emmon Road, just west of Route 71.  A spectacular high quality fen is a short walk from the parking lot — just follow the west trail to the boardwalk to discover its riches.  Lyon and the adjacent Richard Young Forest Preserve create 177 acres of open space.

Lyon has a number of seeps, a type of wetland where groundwater oozes out of the hillsides.  This creates specialized habitat for plants such as the beautiful marsh marigold and the unusual skunk cabbage.
