Adam's Boulders is a bouldering area in the Middle Fork Ranger District of Oregon's Willamette National Forest, managed by the Forest Service. It sits about a mile from Sand Prairie Campground, the closest of several nearby places to base a trip around. The climbing here is all bouldering, with five routes ranging from V1 to V10. The easiest is Si's Highball at V1, and the hardest is Worldstar at V10. The New Workout Plan and Tweaker are both V9, and Alexishitter is V6. The routes are all boulders, so there is no rope climbing to plan for. Summer is the most comfortable time to visit. Typical averages from the nearby Oakridge Fish Hatchery weather station show July and August highs around 80 to 81°F with only two or three wet days a month, while winter brings highs in the low 40s and rain on more than half the days. Sand Prairie Campground is less than a mile away, and Packard Creek Campground and Packard Creek are both about 4 miles off. For more climbing, Hills Creek Spires is roughly 6.6 miles away.
