Wiessner Wall

Wiessner Wall is a climbing area in Devils Lake State Park in Wisconsin, managed by the State Department of Natural Resources. It sits within a cluster of climbing spots that includes Turk's Head and Cleopatra's Needle, all about a tenth of a mile away, and The Cleo Amphitheater and West Bluff 03 - Cleo Amphitheater, so the wall pairs easily with several other climbs in the same corner of the park. The routes here run from trad climbing on the easier end to a top-rope route on the harder side. There are 10 routes in total, with seven done on trad and one on top rope. Grades range from 5.3 to 5.11a on the YDS scale, and bouldering routes add two more options at V0-1. Upper Wiessner Crack is the easiest at 5.3, and Just Another Pretty Face is the hardest at 5.11a. For timing, late spring and early fall are the most comfortable. Typical averages from the nearby Baraboo weather station put May highs around 70°F and September highs around 74°F, with July warming to about 83°F. Winter is cold, with January highs near 28°F. The Iat - Devil's Lake-Baraboo Connection hike starts less than a mile away, and the Iat - Devil's Lake Segment and Northern Trails are both within about 3 miles.
