Ronald's Chasm is a bouldering area in the Santa Catalina Ranger District of Coronado National Forest in Arizona, managed by the Forest Service. It sits among a cluster of climbing and hiking destinations, with The Assassin's Cradle and River Boulder both about 0.1 mile away and North Sabino Canyon Park a similar distance off. The area is a bouldering-only spot, with 12 routes on the V scale, ranging from V1-2 to V9. The median grade is V4-5, and the hardest route is Corpse Reviver at V9. Among the named routes are Ronnie's at V4-5 and Art Isn't Real at V7. Spring and fall are the most comfortable times to visit. Typical averages from a nearby weather station at Mt Lemmon Willow Canyon show May highs around 71°F and October highs around 68°F, with lows near 50°F. That station sits about 400 feet lower than the chasm, so temperatures here run a little cooler. Spencer Canyon campground is about 1.1 miles away, and Whitetail Campground is about 1.7 miles away.
