Great campsite along highway 1 between San Luis Obispo and Morro Bay. Spent a couple nights here in April 2022. No online booking interface when we went and reservations had to be made over the phone. This was a nice alternative to the state parks nearby which were booked solid months in advance.
There are three loops of campsites all of which can accommodate RVs. Romauldo and Chumash campsites are full hookup, mostly back-in. A select few in the Chumash loop have the utility hook-ups on the 'wrong' or left side of the parking space when looking at the site. Check the map included in this post to ensure you don't book one of these sites or be prepared with extension cords and an extra sewer line. The Bishop loop has 10 of 17 designated as pull through but there are no hook-ups in this loop. Clean bathrooms with pay for showers are available.
The Bridge Trail next to Chumash site 15 is a shortcut across Dairy Creek to the playground, botanical gardens and dog park. There are fun exhibits for kids and adults around the nature center with helpful informative staff. There is a short nature trail behind the center with a giant sundial, neat vegetation and all kinds of hawks and raptors soaring around looking for food. At the peak of the loop you can break off toward Eagle Rock trail which leads further up the hill to a giant rock (which looks more like a lion than an eagle to me) and impressive views of the valley.
