The mountain bike trails in Calumet County Park normally open late spring/early summer-due to the Niagara Escarpment's springs, our non-motorized bike trails are usually open later in the mountain biking season. Bikers are always anxious to get on the trails but please call the Parks Activity Line for recorded updates on the trails. (920) 849-1494.
The bike trails are very popular with the mountain bike racers and the every day biker that just enjoys nature and the challenge the bike trails have to offer. Our 2.2 miles of trails wind throughout the park, offering single-track segments through the woods and many scenic views along the trails. You can stop by the office and get a map of the bike trials.
The 2.2 mile Sun Run trail is open to off-road mountain biking, walkers and runners in the summer, and fat-tire bikes and snowshoeing only during the winter months.
The North East Wisconsin Trails club newtrailswi.org maintains the trail and is working on another 2.5 miles of trail that should be open in 2021.
