I don't have a lot to add beyond what has been said by others.  This campground is about the location.  It is nestled right in the state park w/old growth redwood trees and hikes accessible directly from the campground.

However, it is very tight, which is difficult for anyone with a larger trailer.  The facilities are showing their ages as well.  The showers were in decent shape, but the bathrooms could use some work. 

It is still the best campground for exploring the park though.  And the negatives should not turn you away.
