About This Trail

Robinson Canyon and Ainsley Canyon form a gentle loop through the L.T. Murray State Wildlife Recreation Area, one of the more accessible corners of this elk wintering range south of Ellensburg. The route follows Robinson Canyon Road past a gate, mixing single-track trail with old forest road as it winds through the canyon. At the Ainsley Canyon junction, the trail opens into meadows and aspen groves. An abandoned stone ice-house sits in the big meadow further up, making a good lunch spot and turnaround.

Wildflowers peak in May and June, and the fall color from the aspens brings people back in October. The birding is solid throughout, and the creek crossings keep things interesting without being technical. The terrain is mellow enough for kids and dogs, with enough variety to hold your attention over the full 10 miles.

One thing to know: the area closes December through May to protect wintering elk herds, so plan accordingly. The road below where Ainsley Canyon meets Robinson Canyon is washed out, so avoid descending that way. Park at the second gate where the trailhead kiosk stands, not the first gate. A Discover Pass is required. Hunting season in fall brings heavy foot traffic of a different kind, so wear blaze orange if you visit late in the year.

Parking

Drive to the second gate where the trailhead kiosk is located. The first gate is not the trailhead. Discover Pass required. From I-90 exit 101, south on Thorp Highway, right on Killmoor Road for 2.5 miles, then right on Robinson Canyon Road.

Approach

Trail follows Robinson Canyon upstream, alternating between single track and old road. At the Ainsley Canyon junction, continue up to the meadow and abandoned stone ice-house for the best scenery. Do not descend via the canyon bottom below the junction as the road is washed out.

Timing

Check seasonal closure dates before driving out. The area typically reopens in late May. Morning starts give the best chance at wildlife sightings.
