Olympic Peninsula Backcountry Discovery Trail

Olympic Peninsula's forgotten logging empire routes

Moderate

This network of forgotten logging roads and mining access routes carves deep into the Olympic Peninsula’s backcountry, threading between massive old-growth Douglas firs and climbing toward alpine meadows below the Olympic peaks. The route connects abandoned logging camps, crosses the Quinault River system multiple times, and passes the ruins of the Grisdale logging town where steam donkeys once dragged thousand-year-old trees down mountainsides.

Moderate difficulty with some technical creek crossings and steep, rutted climbs through clearcuts. High-clearance 4WD required, with recovery gear recommended for muddy sections during winter months. Best run May through October when snow clears from higher elevations. Dispersed camping available throughout national forest sections, but water sources can be scarce during late summer. This is Washington’s ultimate forest exploration route — raw, remote, and lined with the ghosts of the Northwest’s timber empire.
