    Dorrance Forest Preserve is located right in the middle of Port Byron, IL making it a prime choice for recreation and specifically trails. This 80 acre park features moderate to steep terrain and is covered by large hardwood trees typical of the Mississippi River valley. The park is located just a short ride from downtown Port Byron making it a convenient recreation destination for locals or those just visiting.

    Planned Trails

    Three main loops of trail will be constructed at Dorrance. A green beginner loop, blue intermediate loop, and black advanced skill loop. Each trail will be around 1 mile in length.

    Check out our current plan for the Dorrance Trails. We gave this short presentation to the Village of Port Byron that outlines what we are doing at the park: Dorrance Trails Presentation

    Trail Information

    There is currently one short out-and-back hiking trail/road along the northernmost ridge paralleling Agnes Street.

    FORC is working with RICFPD to develop new trails at Dorrance. The new system is still in the planning phase but dirt moving is scheduled to begin spring 2016. Total singletrack trail mileage when completed is expected to be around 4 miles. Layout will be done as a stacked loop system, like many other local trails, with a main loop that is wider and less technical and a couple more technical/difficult loops branching off. Permitted trail uses are to include mountain biking and other human powered activities.

  • MTB Trail Etiquette

    • Ride Open Trails: Respect trail and road closures — ask a land manager for clarification if you are uncertain about the status of a trail. Do not trespass on private land. Obtain permits or other authorization as required. Be aware that bicycles are not permitted in areas protected as state or federal Wilderness.

    • Leave No Trace: Be sensitive to the dirt beneath you. Wet and muddy trails are more vulnerable to damage than dry ones. When the trail is soft, consider other riding options. This also means staying on existing trails and not creating new ones. Don't cut switchbacks. Be sure to pack out at least as much as you pack in.

    • Control Your Bicycle: Inattention for even a moment could put yourself and others at risk. Obey all bicycle speed regulations and recommendations, and ride within your limits.

    • Yield Appropriately: Do your utmost to let your fellow trail users know you're coming — a friendly greeting or bell ring are good methods. Try to anticipate other trail users as you ride around corners. Bicyclists should yield to other non-motorized trail users, unless the trail is clearly signed for bike-only travel. Bicyclists traveling downhill should yield to ones headed uphill, unless the trail is clearly signed for one-way or downhill-only traffic. In general, strive to make each pass a safe and courteous one.

    • Never Scare Animals: Animals are easily startled by an unannounced approach, a sudden movement or a loud noise. Give animals enough room and time to adjust to you. When passing horses, use special care and follow directions from the horseback riders (ask if uncertain). Running cattle and disturbing wildlife are serious offenses.

    • Plan Ahead: Know your equipment, your ability and the area in which you are riding and prepare accordingly. Strive to be self-sufficient: keep your equipment in good repair and carry necessary supplies for changes in weather or other conditions. Always wear a helmet and appropriate safety gear.
