Devil's Backbone is a climbing area in Backbone State Park in Iowa, managed by the State Department of Natural Resources. The nearest town is Forestville, about 2 miles away. The park's climbing areas sit close together, with Backbone East and Drive In Wall both about 0.1 mile from the Backbone Trail, which makes it easy to string a hike and a climb into one outing. The climbing here is trad, with two routes listed: Monster Crack at 5.10c and Devil's Hideaway at 5.11b. Both are traditional climbs, and the grades put them in the 5.10 to 5.11 range. For timing, late spring and early fall are the most comfortable. Typical averages from a nearby weather station in Manchester show May highs around 70°F and September highs around 74°F, while winter brings highs in the 20s and regular snow days from December through February. Backbone Lake is about a mile away for fishing, and the Maquoketa River Water Trail is roughly 5 miles off for paddling.
