Lost Mule Wall is a climbing area in Joshua Tree National Park in California, managed by the National Park Service. It sits among a cluster of other climbing spots, with Pixar Wall and The Cuckoo's Nest each about 0.1 mile away and Echo Rock Area about 0.2 mile off. The area is a compact, trad-focused destination, with six routes ranging from 5.6 to 5.11a. Spring and fall are the most comfortable times to visit. Typical averages from a nearby weather station in Yucca Valley show April highs around 73°F and October highs around 80°F, while July and August average about 96°F. That station sits roughly 950 feet lower than the wall, so temperatures on the rock run cooler. The routes here are all trad, and the grade range spans from 5.6 to 5.11a.
