nce a railroad, this trail allows visitors to travel between the towns of Chehalis and South Bend without having to drive! This makes an excellent outing, whether you want a quick jaunt or a longer bike ride, though the trail is in varying stages of development, so be sure you are prepared for pavement, gravel, or possibly dirt, depending on your route.

Access is available for hikers, runners, and bikers from the Pe Ell entrance, in Chehalis, or off Dieckman Road, Ceres Hill, or Meskill Road, all near Adna. You can also hop on the trail from Rainbow Falls State Park, where you can ride or walk a short distance from the park’s entrance to the trail itself.

Find the paved section between Chehalis and Bunker Creek. This 5.5 mile stretch sees the most traffic of this trail. From there, the trail becomes graveled, perfect for bicycles with thick tires.

As you walk, keep an eye out for equestrians. In addition to hikers and bikers, horses enjoy this trail from the Adna trailhead, found off Dieckman Road. Equestrians can also access the trail from Pe Ell; a Discover Pass is required for both of these trailheads.

Though the trail runs 56 miles from Chehalis to South Bend, currently it can only be hiked in sections due to its incomplete nature. Several trestle bridges are closed due to a lack of decking, making them unsafe for travelers. Check out a helpful map of mileposts, closures, and notable sights along the way here: bit.ly/1RDKfLG

As of December 2015, trestles at Spooner Road and Doty-Dryad Road have opened. This connects more than 12 miles of trail from Spooner Road west of Adna to Pe Ell.

In June 2016, three more bridges have opened. While the bridge at mile 27 is still difficult to cross, this recent development allows visitors to enjoy an unbroken 27 miles of gravel, paved, and hard-packed dirt road.
