The Willapa Hills Trail, formally known as Willapa Hills State Park Trail, is a passageway for non-motorized vehicles to make their way between Chehalis and the Willapa Bay area just east of the Pacific Ocean. The trail is 56 miles in total, with 22 between Chehalis and Pe Ell continuously accessible as of early June 2016.
The trailhead is about 1/2 back from the paved road. The Hagador Trail is about 4.5 mile round trip. 2) the Tin Mine Trail (entrance by some rocks just before the first big incline) on Skyline Drive Trails. According to the sign, it was approximately 1 1/4 mile to the mine so about 2 1/2 miles round trip. I was surprised to see quite a number of people here.
