At Calumet County Park, the park personnel are very enthusiastic about mountain bike use, and the trails are used for an extremely popular Wisconsin Off-Road Series race called the Calumet County Sun Run. There isn’t a lot of mileage here but all trails are open for riding and many combinations are possible. There are several long, steep climbs throughout but technical skills required only include these climbs and some tight turns but the trails are smooth. A favorite spot is the steep trail to the top of the Niagara escarpment where you will ride through a beautiful stand of maples and past fractured blocks of limestone. On top, heading south, the trail takes you past several panther effigy mounds before turning toward the lake, down twisty switchbacks.
