Mi Boulder is a climbing area in the Trabuco Ranger District of Cleveland National Forest in California, managed by the Forest Service. It sits within a cluster of bouldering and climbing spots that make it easy to build a full day of routes around. Spring and fall are the most comfortable times to visit. Typical averages from a nearby weather station in Elsinore show April highs around 76°F and November highs near 73°F, while July and August climb to the mid-90s. That station sits well below the area, so temperatures up high run cooler. Ortega Falls and Toprope Wall are both about 0.1 mile away, and San Juan Canyon is about 0.7 mile off. For a hike, Chiquito is about a mile away.
