Aspen Trail Boulders is a climbing area in the Santa Catalina Ranger District of Coronado National Forest in Arizona, managed by the Forest Service. It sits in a cluster of boulders and climbing spots, with several other areas within a short distance. For comfortable weather, late spring and early fall are the sweet spots. Typical averages from the nearby Mt Lemmon Willow Canyon weather station run from highs around 71°F with lows near 51°F in May to highs near 75°F and lows around 59°F in September, and the station sits a few hundred feet lower than the boulders, so temperatures here may run a bit cooler. The closest neighbors are Havens, The, about 0.1 mile away, and Sloth Slab, about 0.2 mile away. Ronald's Chasm and North Sabino Canyon Park are both within about a third of a mile. For an overnight stay, Spencer Canyon Campground is about 1.2 miles away.
