Drive In Wall is a climbing area in Backbone State Park in Iowa, managed by the State Department of Natural Resources. It sits among several other climbing spots and trails in the park, including Backbone East, Devil's Backbone and the Backbone Trail, all within about a tenth of a mile. The area has seven routes, five of which are trad and two top rope. Grades run from 5.7 up to 5.12b, with the hardest being the top-rope "Bride of Nemesis" at 5.12b. "Stairway to Heaven" is a 5.7 trad route, and "Lefty and Poncho" is a 5.10b trad route. For timing, late spring and early fall are the most comfortable. Typical averages from a nearby weather station in Manchester put May highs around 70°F and September highs around 74°F, while winter brings highs in the 20s and regular snow days. Backbone Lake is about a mile away for fishing, and the Maquoketa River Water Trail is roughly 5 miles off for paddling.
