When we were there it was quite dirty at the shore, there were some spots at the far end that were fine and we didn't see the rubbish. It should've been taken care of.
Cape Perpetua Scenic Area includes everything from tide pools at the edge of the ocean to a dramatic cleft in the rocks where the waves come crashing in. There are over 20 miles of hiking trails here. But you don't have to be a hiker to enjoy this place - much of it can be seen with short easy walks on level paved surfaces.
