The Comp Wall is a climbing area within Castle Rocks State Park in Idaho, managed by State Park and Recreation. It sits among a cluster of named climbing areas in the park, including Comp Rock, Bracksiek's Pillar and Taco Cave, each about 0.1 mile away. The nearby Backyard Boulders Return Route hike starts about 0.6 mile from the wall. The area has nine climbing routes, with styles ranging from traditional to sport and mixed, and grades from 5.9 up to 5.11. La Vida is a 5.9 trad route, and Women's Semi-Qualifier is a 5.11b sport route. The median grade is 5.10c. The closest climbing areas, such as Comp Rock and Bracksiek's Pillar, make it easy to pair with other outings on the same outing. Summer is the warmest time to climb. Typical averages from a nearby weather station in Oakley show July and August highs around 86°F with lows in the mid-50s. That station sits about 1,600 feet lower than the park, so temperatures on the wall run cooler.
