Black Wall is a bouldering area in Phoenix South Mountain Park, on city land in Phoenix, Arizona. It sits among a cluster of other climbing spots, with Entrance Boulders, The Big Roof and World Boulder all about 0.1 mile away, and The Studio about 0.2 mile off. The park's trails, including the Mormon Loop Trail and Guadalupe Perimeter Trail, are within half a mile. The climbing here is all bouldering, with five routes spread across a range of grades from V1 to V9-10. The most straightforward is Flippin the Bitch at V1, and the hardest is Black Star at V9-10. Black Wall itself is a V6 boulder problem. The area works well for a short session, with several problems close together. Winter and early spring are the most comfortable times to visit. Typical averages from a nearby weather station in South Phoenix show January highs around 67°F and lows near 42°F, while summer highs climb into the 100s. That station sits about 600 feet lower than the park, so temperatures on the boulders run a little cooler.
