This 23-mile scenic corridor currently passes through the heart of the wildlife-rich Turnbull National Wildlife Refuge. The route offers opportunities to see interpretive panels, numerous wildlife species, and associated scenic landscapes. Trail signage indicates key features along the trail, as well as mile markers with numbers referencing the distance from Portland, Oregon, as established by the Spokane--Portland--Seattle Railroad in the early 1900s.

The old railroad right-of-way slices through the heart of one of the richest wildlife areas in Washington. From the trailhead, amble to the south and enjoy the desert scenery on both sides of the trail. Because the route is smooth and level, you can cover many more miles than you might expect.

The trail angles past Amber Lake--stay on the trail, because moose are sometimes seen lumbering through the area near the lake--and cuts through the high desert sagelands to the southeast. Bald eagles can frequently be seen overhead as they soar aloft while searching area lakes for fish. Mule deer also frequent the area.

In 7 miles, you'll reach another trailhead at Martin Road. Turn around here or continue as far as you like, for a total mileage of up to 23 miles (one-way).

Note: This trail is open to bicycle traffic, so stay alert when walking here.
