This is Devil’s Gate, located along the Bad River in Copper Falls State Park. The park is in northern Wisconsin and features a wonderful hike which follows the river and passes a couple waterfalls and this rock formation, which is far less intimidating than the name suggests.
The waterfalls in Wisconsin may not be as impressive as those in Iceland or Hawaii but there are some that are worth seeing. Copper Falls State Park is a beautiful state park in northern Wisconsin at the intersection of two rivers. The park has a couple waterfalls (spoiler alert: one of them is named Copper Falls), trails with great views of the rivers and surrounding forest, and interesting geology. We visited on a fall day several years ago to see the waterfalls and enjoy the fall colors. The hiking was great due to the beautiful fall weather but the fall colors were just a little before their peak. While many of the trees in the park had leaves that had turned yellow, those that turn red and orange had not really started changing their color yet. Fortunately, the few trees that had started turning already just happened to be right next to Copper Falls.
