The Chehalis River Cabin is located on the north bank of the Chehalis River (right behind that big tree sticking out over the water on the right). It's 17 miles west of I-5 (exit 77 as it meets Chehalis, WA), one mile west of Rainbow Falls State Park (don't miss the falls), and just 35 miles east of Willapa Bay (on the Pacific Ocean) where you'll find the best fresh oysters in the world.
