This is a huge (over 125 sites) and very popular campground. I strongly urge you to make reservations in advance as it was almost sold out on even a cool, overcast weekday. Most campsites are mixed use, with only a tiny handful tent only (and only 2 that are hike/bike in-I asked). Personally, I liked the farthest back loop because it was less crowded, kind of sheltered, and hand the least traffic. It’s also closest to the Monarch Butterfly Roosting area, tho I didn’t see any on my walk through. The back loop is also close to the only trailhead in the campground, the Black Hill Trail (I didn’t hike it, so I can’t tell if it was a good one or not). Across the road from the entrance is the Marina where you can rent a slip for your boat or rent a kayak for the day. Just up the road thru town is the big draw: Morro Rock. I had a great time hanging out watching the sea otters in the calm waters on one side of the rock and the surfers on the other side. Lots of beach walkers too.
