Collier Bar is a 5.6-mile out-and-back hike in the Kalmiopsis Wilderness, part of the Wild Rivers Ranger District of the Rogue River-Siskiyou National Forests in southern Oregon. The Forest Service manages the land, and the nearest town is Agness, about 10 miles away. The trail is rated moderate, with a one-way climb of about 1,258 feet from a low point of 264 feet to a high of 1,314 feet. It is a natural-surface route, and horses are allowed. Bikes are not, and the trail is not accessible. For comfortable weather, aim for late spring or early fall. Typical averages from the nearby Illahe weather station show May highs around 75°F and October highs near 69°F, while July and August average about 90°F. That station sits well below the trail, so temperatures on the route run cooler. Nearby options include the South Bend Mountain Way, about 2 miles away, and Hurt Cabin and Horse Sign Butte, both within 4 miles. For an overnight base, Oak Flat Campground/Gravel Bar is about 7 miles off.
