Entrance is a bit confusing because of the sign placement. Some sites have grass while others are just gravel. Not a destination park, but fine for an overnight or for a base camp from which to explore.
We've visited this park several times. It's a reasonably short walk to the beach and close to Monterey. We've stayed at the fairgrounds in the past, but much prefer this site. The only issue we have is the road noise, but it does quiet down at night. Our rig is 33' long.
