Seattle, WA: Fifteenmile Creek

Explore the wilder side of Tiger Mountain State Forest on this 10-mile out-and-back that winds through lush forest, passes artifacts from a 1920’s train wreck, and visits the banks of Fifteenmile Creek.

Trip Tools

Bypass the peaks in Tiger Mountain State Forest and explore the more remote recesses of the 13,500-acre working forest on this 10-mile out-and-back to Fifteenmile Creek. The hike begins on a logging road, but quickly veers onto the Iverson Railroad Trail; you’ll tromp past clear cut areas and enter a young forest of cedar and fir before pushing deeper into more mature stands. Roughly 2 miles in, turn right onto the logging road and follow it less than half a mile to the Tiger Mountain Trail.
After turning right onto Tiger Mountain Trail, hike north to a junction with Artifacts Trail. Bear right and visit the site of a 1920’s train wreck (look for the twisted metal remnants next to Holder Creek). A pile of rusted wheel sets and spring boxes sit on one side of the trail; mangled rails and moss-covered railroad ties lean haphazardly against several trees. At mile 3.2, merge back onto Tiger Mountain Trail at Karl’s Gap and follow it to the junction with Hobart Trail. Bear left at this Y-junction and descend to Fifteenmile Creek. Take in the picturesque scene before turning around and following the same route back to the trailhead.
