Tiger Mountain State Forest: Preston Railroad Trail / Northwest Timber Trail Loop. Professional Review and Guide
"This 11.3-mile loop, suitable for strong intermediates and above, is by far the most entertaining ride available to mountain bikers in Tiger Mountain State Forest. The woods and trails are the highlight of the ride, as views are few. The route travels through second-growth clear-cuts, but also Douglas fir, western red cedar, western hemlock, red alder, and big-leaf maple. At the time of research, the Preston Railroad Trail was graveled for the first 0.6 mile, but the gravel mounds on the side of the trail along the rest of the way indicated more coverage to come.
The gravel trail was fun to ride, but it eliminated the rooty, rocky technical challenges encountered on the rest of the trail. The Northwest Timber Trail was much smoother, and by itself can make for an out-and-back, virtually all singletrack route. Scenery: Brief glimpses of Mt. Rainier and valleys below on the initial road climb; trails go under the cover of second-growth woods."
