Grandfather Falls in Rock Falls, Wisconsin offers visitors a unique hiking experience along the Ice Age National Scenic Trail. The challenging trail features rocky terrain with exposed roots and runs alongside the water, making it best suited for sure-footed hikers rather than young children or strollers. While the falls themselves are more like rapids these days, the scenic views, photo opportunities, and ability to get close to the water make it a memorable outdoor destination for those willing to navigate the rugged path.
