City of Rocks Bouldering is a bouldering area within City of Rocks National Reserve in Idaho, managed by State Park and Recreation. It sits among a cluster of climbing areas, with Creekside and The Office both about 0.1 mile away and Anteater - West and Anteater - East about 0.2 mile off. The reserve's boulders make for a compact, close-together destination for climbers. The climbing here is all bouldering, with three routes listed: The Nest at V2, American Standard at V6-7 and Songbird at V7. The grades run from easy to challenging, so there is something for climbers of different abilities. For timing, late spring and early fall are the most comfortable. Typical averages from a nearby weather station in Rosette, Utah, show May highs around 65°F and September highs around 74°F, with July peaking near 86°F. That station sits about 770 feet lower than the reserve, so temperatures on the boulders run cooler. Independence Lakes Campground, about 10 miles away, is the closest place to camp.
