Astronomy Wall is a climbing area in the Canyon Lakes Ranger District of the Arapaho and Roosevelt National Forests in Colorado, managed by the Forest Service. It sits among a cluster of other climbing spots, with Jungle Wall, West Side Crags and Horizon Wall all about 0.1 mile away. Summer is the most comfortable time to visit. Typical averages from a nearby weather station at Rustic, about 6.4 miles away, show July highs around 78°F with lows near 47°F, and the station sits roughly 700 feet lower than the wall, so temperatures on the rock run cooler. Poudre Falls Climbing Access is about 0.2 mile away, and Big South Campground is about a mile off. Aspen Glen Campground is about 2 miles away, and Joe Wright Creek, a canoeing spot, is about 4 miles away.
