Emperor's Boulder is a bouldering area in Rib Mountain State Park in Wisconsin, managed by the State Department of Natural Resources. It sits among a cluster of climbing areas, with Smell the Moss, Wrestling with Alligators and Jurassics all about 0.1 mile away. The boulders here are rated from V1+ to V4, with the median grade at V3. The routes include Emperor's New Clothes (V2), The Last Emperor (V3) and Emperor Penguin (V4). The area is a compact, close-together set of problems, so it works well as a short stop among the park's other climbing. Summer is the most comfortable time to visit. Typical July highs reach about 80°F with lows near 59°F, based on averages from a nearby weather station in Wausau. That station sits roughly 650 feet lower than the park, so temperatures on the boulders run a little cooler. The Yellow Trail and Red Trail are both about 0.3 mile away, and Granite Peak Ski Area is about 0.4 mile off.
