Curly Creek Falls Via Lewis River Trail is a 0.8 mile out and back trail located near Stevenson, Washington and is good for all skill levels. The trail is primarily used for hiking and is accessible from March until November.
This is a nice stop on a day trip through the area. Curly Creek falls is pretty unique, falling through a natural arch and definitely worth seeing. Unfortunately, it was dry this August when we were there, but I bet it is really cool in the spring. Not much of a hike, but a nice stop on a driving tour of the area, or as a side trip before or after another hike in the region.
Don't think the falls is a mile down. It might be close to a mile going all the way down to Miller Creek Falls and back.
Didn't go very far down this trail. Stopped at the beginning and was a little disappointed how far the waterfall was away from any sign of a trail that went down to it.
