🏆🏆🏆🏆 Rail Trail Pioneer — 56-mile rail trail through the forested hills of southwestern Washington — following the historic Northern Pacific Railway route
Willapa Hills State Park Trail is a 56-mile rail trail running from Chehalis to the Pacific coast — following the route of the historic Northern Pacific Railway through the forested hills of southwestern Washington. The trail passes through towering Douglas fir forests, across the Willapa Hills, and down to the coast near Willapa Bay. The Northern Pacific Railway was the first transcontinental railroad to reach the Pacific Northwest (1883) — connecting the Puget Sound to the eastern US and triggering a massive wave of settlement. The trail offers a gentle grade (never exceeding 3%) ideal for cycling and hiking.
