Obsidian Limited Entry Area

The Obsidian Limited Entry Area, within the Three Sisters Wilderness, requires additional protection in an effort to preserve the natural beauty and wilderness experience; therefore a limited entry quota is in effect. Under this quota, 30 day hikers and 40 overnight visitors are permitted into the area each day. Permits become available for advanced reservation annually on May 1, for season dates beginning the Friday of the Memorial Day holiday weekend and ending October 31. The road to the Obsidian Trailhead does not open to motor vehicles until the third Monday in June at the earliest, depending on snow conditions; the road is always open to non-motorized use. This unique landscape encompasses crystal clear streams, wildflower meadows, rugged mountain views, young lava flows and obsidian cliffs. The cliffs were an important source of naturally occurring volcanic glass used by Native Americans to craft tools. The area contains a number of lakes, streams and springs, including Obsidian Falls, which can be viewed from the trail. The trail also passes through lava flows and over ridges that offer breathtaking mountain views. Cross-country travel skills are necessary to access the high lakes and mountain peaks. Obsidian is abundant throughout the area and makes up a large part of its rich cultural history. Backpacking, day hiking, mountaineering and horseback riding are the most common forms of recreation during the short summer season, after snow has receded, and opportunities for nature photography abound. Access begins at the Obsidian Trailhead, just off historic Highway 242. The Obsidian Trail #3528 climbs more than 2,000 feet in elevation, branching to the left to connect to Trail #4336; both trails connect to the Pacific Crest National Scenic Trail, providing a popular 12-mile, day-long loop for hiking or riding. Hikers and equestrians should obtain a detailed map of the area before planning a trip, and inquire in advance about trail conditions, particularly early in the season. There are no facilities within the Limited Entry Area or the Wilderness Area. Facilities at the trailhead include parking, bathrooms, picnic tables, stock hitching posts, and wilderness and interpretive information. Visitors must practice Leave No Trace skills, including properly disposing of human and pet waste and packing and carrying out all trash. Use of the Obsidian Trailhead also requires a recreation pass, such as the Northwest Forest Pass, which must be obtained before arriving at the trailhead — from the McKenzie River Ranger Station, online (day passes only) or from an authorized vendor. The Obsidian Limited Entry Area is along the McKenzie Pass-Santiam Pass National Scenic Byway on Highway 242, with many hiking and camping opportunities along the highway. Major attractions include the Proxy Falls waterfall hike and the Dee Wright Observatory, built into the lava rock at the top of McKenzie Pass, which provides spectacular views of volcanoes in the area.
