Devil's Churn is best seen at high tide. This is a big cleft in the rocks where the ocean waves rush in, splash up into the air, then whoosh back out.
We walked down the paved pathway to get a closer look. I suggest wearing walking shoes, not sandals! If you are reasonably fit you can get quite close to the waves.
The surrounding area is lovely and is part of the Cape Perpetua Scenic Area. There is off street parking as well as restrooms. If they are not too busy, there is usually room for RVs.
Devil's Churn is easy to find as it's located right on Highway 101, where the road makes a sharp turn. There is another paved viewpoint a mile or so south where you can also see lots of splashing waves and sometimes a blowhole - that is Cook's Chasm - so don't confuse the two places!
This is an interesting place to visit even at low tide, but we like to catch it at high tide for the most dramatic waves. If you are lucky enough to visit during a winter higher tides it's really incredible.
