North Fork Asotin Creek

Explore a riparian corridor and canyon, rich with wildlife—upland birds, large and small mammals, hibernating ladybugs—and wildflowers in late spring and early summer. This uncrowded trail is open most of the year and spends nearly equal time in the Asotin Wildlife Area and the Umatilla National Forest.

getting there

Drive SR-129 (Riverside Drive) to Asotin, 6.0 miles south of Clarkston. Just before the bridge crossing in Asotin, turn right onto Bauermeister Drive which becomes Asotin Creek Road, and drive 2.9 miles. Turn right onto County Road 1100, drive 11.2 miles, and bear right at the fork onto County Road 181 (South Fork Asotin Creek - Lick Creek Road). Drive 0.5 mile to the Asotin Wildlife Area gate. The gate is closed Dec 1 to Apr 1.  Drive (high-clearance vehicles are recommended) or walk 0.3 mi to trailhead (1,990 ft) on left at confluence of Lick Creek and North Fork Asotin Creek.

on the trail

Out-and Back: 20 miles round trip with 1,750 feet of elevation gain
Loop: 22.4-mile loop with 3, 049 feet of elevation gain
One-way: 14 miles one-way with 3, 049 feet of elevation gain

Hike along North Fork Asotin Creek through Asotin Wildlife Area on a wide trail for first four miles to the Umatilla National Forest boundary. The trail through the wildlife area is an old road bed, mostly gravel, maintained by user groups, and closed to motorcycles year-round.  Hike six miles from the national forest boundary on narrow trail to a possible turnaround point near the confluence with Middle Branch of the North Fork Asotin Creek. From here, return the way you came or hike switchbacks 1.5 miles up the North Pinkham Butte Trail continuing to follow the North Fork Asotin Creek. Complete the loop on the South Pinkham Butte Trail that descends to the North Fork Asotin Creek Trail.

One-way Option: For a 14-mile, one-way trek in either direction,  after the Lick Creek Road opens and snow melts (usually by June), leave a vehicle at the trailhead on Lick Creek Road near the junction of Forest Roads 41 and 4026, 11.5 miles from North Fork Asotin Creek Tailhead. No pass is required to park here.

Exploring nature

Enjoy a variety of wildlife wonders along this creek near the Snake River:  wintering deer, elk, bighorn sheep, and hibernating ladybugs. This area is an elk calving area, a quail recovery area, home to upland birds, and a spawning area for migrating steelhead. Expect to see signs of black bear and cougar in this prey-rich area. Watch out for rattlesnakes, ticks, blackberry vines, and poison ivy.

  • Visit in May and Jun for wildflowers.
  • Visit in spring for big mammals, wild turkeys, grouse in streamside vegetation, chukars calling from the basalt outcroppings, spiraling calls of canyon wrens, and more.
  • Look for wintering mammals in the wildlife area's valley and beyond, and hibernating ladybugs  (thousands of them!) in the meadow past the basalt cliffs near the confluence of the Middle Branch of the North Fork Asotin Creek.
