There appears to be a couple of separate campgrounds… the one I camped at is called Abalone Point.  I was unsure if it was open because there was nobody around and an old road was falling into the ocean.  Primitive campground with no showers or camp host. There was a toilet (hole in the ground), a table, and water.  What you do get is peace and quiet and an amazing view of the ocean. Self payment and was $3 for hike and bike.
