Abert Rim Access Road — Lake Abert to Warner Valley Desert Escarpment

Abert Rim is one of Oregon’s most dramatic landforms — a sheer fault escarpment rising nearly 2,500 feet above the alkaline flats of Lake Abert on its west face. The rim road departs from an unmarked BLM two-track off US-395 south of Valley Falls and grinds up through juniper and sagebrush before breaking onto the basalt rim itself. From the top, you’re looking straight down at one of North America’s largest remaining alkaline lakes, a breeding ground for migratory birds so rich it’s been designated an Outstanding Resource Water. The route works north along the rim edge past Colvin Flat before dropping back toward the Warner Valley basin.

Moderate difficulty in dry conditions — the climb to the rim involves loose basalt rubble and a few steep pitches that demand genuine 4-low traction. In wet conditions or after snow, don’t even attempt the descent sections. No cell service, no water on the rim. Carry fuel from Lakeview, 25 miles south. No permit or fee required. Best season is June through October. The solitude up top is complete — you can camp right on the rim with the wind and the hawks, and that’s worth every rough mile of the approach.
