My wife and I stopped at Devil's Churn on our way back to Eugene after spending a day in Yachats.
This is a rather short (less than 1 mile) loop from the parking lot, down to Devil's Churn and taking the loop to enjoy the view of the Southern shoreline.
The Devil's churn itself is worth the stop; the narrow cut channels the waves for the most entertaining "crashing" effect if the ocean is in the mood. My wife even saw a whale breaching nearby as I was navigating the somewhat slippery rocks bordering the sluice. Just be careful and aware: large waves can really drench you... or possible worst.
What an amazing place to enjoy and respect the forces of nature!
John S. on Amanda Trail
A solid coastal trail hike with views of the coastline in a few places. Nice trail through the woods.
