Obsidian Trail #3528

  

This unique landscape in the Three Sisters Wilderness 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 construct 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.

Backpacking, day hiking, mountaineering and horseback riding are the most common forms of recreation in the area during the short summer season, after snow has receded. Opportunities for nature photography also abound.

The Obsidian Limited Entry Area 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.

Access begins at the Obsidian Trailhead, located just off historic Highway 242 (closed during the winter and spring). The Obsidian Trail #3528 climbs more than 2,000 feet in elevation, through a forest of mixed Lodgepole Pine and Hemlock alpine forest then passing through a lava flow. Views of the Three Sisters and other surrounding mountains are available on this lava flow. After passing through the flow, the trail crosses White Branch Creek and then heads uphill through alpine forests and meadows, crossing many streams along the way. The trail reaches its terminus at the Pacific Crest Trail #2000. Connecting to Glacier Way Trail #4336 provides a popular 12-mile, day- loop for hiking or riding.

Facilities at the trailhead include parking, bathrooms, picnic tables, stock hitching posts and wilderness and interpretive information about the area.
