Mushroom Boulder is a bouldering area in New Mexico, within the Kiowa/Rita Blanca National Grasslands ranger district of the Cibola National Forest, managed by the Forest Service. It sits among several other climbing areas, including the West Face, South Face and Roadside Attraction Boulder, all within a tenth of a mile. The closest campground is Mills Canyon Rim Campground, about 0.4 miles away. The area's three climbing routes are all boulders, ranging from V4-5 to V8, with Battlepunt at V5 and Bowling Baller at V8. The boulders are close together, so a visit can easily include more than one. Spring and fall are the most comfortable times to go. Typical averages from the nearby Roy weather station, about 15 miles away, show May highs near 76°F and October highs near 69°F, while July highs reach about 88°F and winter lows drop to around 21°F.
