On the Trail

This mostly flat trail connects Cheyalis to the Washington coast on a converted railroad bed. Surface conditions vary between the cities of Chehalis and South Bend. From Chehalis to Adna the trail is paved. From Adna to Pe Ell it is compacted gravel and west of Pe Ell, is un-improved with rough sections of railroad ballast. Depending on bikes used and rider’s skills this section may be very challenging to some. Between Raymond and South Bend the trail is also paved. Riding the entire trail from Cheyalis to South Bend and back is 112 miles. Multiple access points along the trail allow for shorter trips.


Rainbow Falls State Park where there are hiker/biker campsites and at Bruceport County Park in South Bend (reservations recommended on summer weekends).
