We did not hike this entire trail but did the portion between the lower and middle falls about 2 miles apart. Easy trail, open to bikes, with some steep drop offs to the river below. Especially notable is the campground located at the lower falls. Still operated by the forest service (not a vendor), it's especially pretty. The lower falls are paticularly impressive, see photo. About 50+ miles east of I-5 on the Lewis River Road. Gateway to the high country around Mt Adams.
