Acker Rock is a climbing area in the Tiller Ranger District of Oregon's Umpqua National Forest, managed by the Forest Service. It sits right beside Acker Rock Lookout, a campground about 0.1 mile away, which makes it an easy base for a day on the rock. The area has 17 routes, with 12 in sport style and 5 in trad. Grades run from 5.4 to 5.10c, with the median at 5.8. Among the trad routes are Orc Bypass (5.4) and Saddle Crack (5.7), and the sport route Black Magic (5.10c) is the hardest listed. Summer is the most comfortable time to climb. Typical averages from a nearby weather station show July and August highs around 79°F with only about four wet days a month, while winter brings highs in the upper 30s and regular snow days.
