Getting Oriented
The byway runs in Lake and Harney counties, the lowest-population corner of southeastern Oregon. Lakeview on US-395 is the southern service hub; Frenchglen is the closest small settlement to the northern end. The route crosses one of the most pronghorn-rich basins in North America and includes the Hart Mountain National Antelope Refuge, established in 1936 as one of the first refuges specifically for pronghorn protection.
Trail Overview
From Lakeview, drive east on Oregon-140 through the Warner Mountains. The byway turns north at Plush onto the Plush Cutoff Road, climbing past the Warner Lakes wetlands and entering the Hart Mountain refuge. Inside the refuge, the road climbs onto the Hart Mountain plateau, passes the Hot Springs Campground, and continues north across the plateau before descending into the Catlow Valley. From Catlow Valley, the route follows the Long Hollow Road to its junction with Oregon-205 north of Frenchglen.
Driving the full byway takes 4 to 6 hours. Most travelers spend at least one night camping at the Hart Mountain Hot Springs Campground or dispersed in the Catlow Valley, turning the byway into a 2-3 day trip.
