The rock is a homogeneous, dark red-brown to mostly purple quartzite, which fractures very cleanly to leave angular features and smooth, almost shiny surfaces. Climb ratings run the gamut, from 5.1 to 5.13a. Devil's Lake cliffs are 30 to 90 feet high, forming a large bowl around Devil's Lake.
Most moderate routes follow one of the many vertical cracks.
By very actively maintained local tradition, there is only one bolted route in the entire park, so bring a rack or plan to top rope everything. Camping is available in the park year-round, though very crowded during the summer. Several local campgrounds including Wheeler's Campground, just north of the park, does its best to accommodate climbers. There is also a small climbing shop there. Several motels are also available in Baraboo, except on summer weekends, when they are likewise solidly jammed with tourists.
