The Moonstone is a climbing area in Joshua Tree National Park, within the Joshua Tree Wilderness in California, managed by the National Park Service. It sits among a cluster of other climbing spots, with North Astro Dome - Northeast Face and Perry Masonary each about 0.1 mile away. 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 1,150 feet lower than the area, so temperatures here run cooler. The area has six trad routes, with grades ranging from 5.6 to 5.10-. One Small Step and The Moonwalk are both 5.6, and Anty Matter is 5.10a. The Moonwalk and Anty Matter were both first ascended by John Thackray and Todd Swain in 1987. The Astrodome Approach Trail and Barker Dam Trail are both about 0.7 mile away, and Sheep Pass Group campground is about 3.3 miles off.
