Show Connector Trails
This trail system contains mountain bike trails, which can become soft and are easily damaged after 0.75 or more inches of rain or long stretches of wet weather. Please consult QC Friends of Off-Road Cycling (FORC), http://www.qcforc.org, to make sure trails are open before heading out.
From the center of Port Byron, travel north on IL-84 for approximately 0.7 miles. Turn right onto 94th Avenue North. The park entrance will be on the right after 0.1 miles, just past a baseball diamond.
Upon entering Dorrance Forest Preserve, several baseball diamonds, restrooms, and a playground are immediately apparent. A closer look however reveals a network of trails. From the access road, there is an out-and-back hiking trail along an old fire road through the woods along the northernmost ridge in the park, which provides good opportunities for bird watching.
Additionally, there is a mountain biking loop of over a mile winding its way around the baseball diamonds and near several stream beds in the eastern section of the park. This single-track loop is reasonably wide and suitable for beginner mountain bikers. There are also two other loops of similar lengths but higher difficulty, completed in 2018. For more information and a trail map visit QC Friends of Off-Road Cycling online.
To reduce erosion, the trails are generally closed for 24 hours or more after 0.2 inches or more of rain, and during winter freeze/thaw cycles.
Dorrance Forest Preserve is managed by the Rock Island County Forest Preserve District.
