Begin in the Old Mills parking lot located on 18th Street E. Head south along the paved trail running parallel to the railroad tracks. This trail is part of a 10-mile loop that leads out of the park and past the banks of the Mississippi. In approximately ½ mile, you’ll cross a long, wooden bridge spanning a dramatically deep limestone gorge. Follow the trail west through Vermillion Falls Park. In roughly ½ mile, you’ll see an observation deck on your right. This gives you an excellent top-down view of the falls and the remains of the mill. For an even better view, follow the well-worn footpath through the trees and scramble along the falls’ slick, limestone base.
