Copper Falls State Park Professional Review and Guide
"For those interested in getting away from it all, why not go big and really do it? Copper Falls is as far out of the way as they come, located just 30 miles off the Lake Superior shore in the northwestern portion of the state. The park surrounds some of the most exciting whitewater action the Bad River— or any other river in the state, for that matter—has to offer. As for mountain biking, 4.5 miles of off-road trails wind through the forest in two separate figure-eight loops. A third 3-mile section of riding is located south of the park entrance and covers easier terrain than the two northern loops.
The trails are comparable to those at Devil’s Lake, definitely worth exploring but separated by some distance from the truly breathtaking natural features the park has to offer. The majority of the riding takes place on forest floor-type terrain, an uneven path of pine needles, grass, and soil. In some places the wide path is worn down in the middle to a singletrack path. It will take intermediate riders approximately two hours to explore the three trails found within the park, though speed is definitely not the goal here. The purpose of riding at Copper Falls is to explore the forest and enjoy the natural beauty."
