Wildflower Bloom in Central and Eastern Washington

March 22, 2008

Yakima Skyline Trail

Sagebrush Violets: Viola trinervata - Photographed along the Yakima Skyline Trail................March 22, 2008.

The Yakima Skyline Trail can be accessed by driving north from Selah, WA on N. Wenas Road. After several miles, turn right onto Gibson Road for about one-quarter mile. Turn right onto gravelled Buffalo Road, proceeding straight, then after the sharp turn to the right, turn left into the parking area (surrounded by fencing). If one has a high clearance vehicle, one can proceed through the gate and drive uphill for about another mile to a grassy parking area. The trail hiked was this western loop of the trail to the summit of the ridge.

A second parking area can be accessed by proceeding straight on Buffalo Road past the first parking area, then eventually working back uphill to a trailhead on the bluffs above the west bank of the Yakima River.
