This is a short trail that climbs from the parking area to the monument. You could always drive up to the monument, but where is the fun in that? From the lower parking area you first climb some metal stairs, and then continue to climb up the ravine to the upper parking area. From there it is a short walk down a paved path to the small "castle" monument. You cannot go inside the castle, but the view of the river and of Dubuque from the monument is spectacular.
