The Obsidian Trail leads to Sunshine, one of the most beautiful and heavily used alpine areas in Oregon. Brooks meander through the wildflower meadows nestled here between Middle Sister and Little Brother. Snowmelt tarns shimmer from plateaus strewn with black obsidian glass.
To limit crowds, the Forest Service requires that people headed for the area within a mile or two of Obsidian Falls get a special permit in advance. Permits for the entire summer are available beginning at 7am Pacific Time on May 1 at www.recreation.gov or 1-877-444-6777.
