The Green Wall is a climbing area within Castle Rocks State Park in Idaho, managed by State Park and Recreation. It sits among a cluster of other climbing spots, including the East Sector, Taco, The and Taco Cave, all within about a tenth of a mile. Summer is the most comfortable time to visit. Typical averages from the nearby Oakley weather station show July and August highs around 86°F with lows in the mid-50s, and September stays mild with highs near 77°F. That station sits well below the park, so temperatures at the wall run cooler. The Backyard Boulders Return Route hike is under a mile away. Independence Lakes Campground, about 5.6 miles off, offers a place to stay.
