The Grouse Boulders is a bouldering area in Wyoming's Jackson Canyon Area of Critical Environmental Concern, managed by the Bureau of Land Management. It sits among a cluster of climbing spots, with Tiggers Treehouse about 0.1 mile away and The Elks Lounge about 0.3 mile away, making it easy to pair with other boulders in the same stretch. The area holds nine bouldering routes, all rated on the V scale from V0 to V8. The easiest are Blue and Ruffed, both V0, and the hardest is Midnight Blues at V8. Pocket Protector is V1, and Ankle Biter is V5. The routes are all boulders, so there is no climbing on rope here. Summer is the most comfortable time to visit. Typical averages from a nearby weather station show July highs around 84°F with lows near 54°F, while winter brings highs in the mid-30s and regular snow days from December through February. That station sits about 770 feet lower than the boulders, so temperatures on the rocks run cooler. For a change from bouldering, Crooked Pine Trail and Split Rock Trail are both within about 4 miles. Lodgepole Campground and Rim Campground, each about 7 miles away, offer places to stay.
