Sisters, OR
A lava-rock shelter built by the CCC in 1935 at the top of McKenzie Pass, surrounded by a sea of black lava. Window slits frame a dozen Cascade peaks; a paved half-mile trail explores the flow.
Dee Wright Observatory is a lookout built of lava rock on McKenzie Pass in the Oregon Cascades, west of Sisters. The Civilian Conservation Corps completed it in 1935. It stands at 5,187 feet (about 1,581 meters) in the middle of black lava fields covering about 170 square kilometers (65 square miles). The small, fortress-like building has window openings through which you can see about a dozen volcanic cones and mountain peaks on a clear day.
Visible peaks include Mount Washington, Mount Jefferson, the Three Sisters and, about 126 kilometers (78 miles) away, Mount Hood. The Lava River National Recreation Trail, a roughly 800-meter (half-mile) interpretive trail across the lava field, starts right at the observatory.
The approach is Oregon Route 242, which is closed in winter; it opens in mid-June at the earliest and closes in fall, usually in October or November. In 2026 it opened on June 15; check current status on tripcheck.com (as of October 2026). Vehicles over 35 feet (about 10.7 meters) are not allowed on the route, so RVs with trailers need to plan ahead.
