We camped here a week before Christmas. We have a 24 ft travel trailer. Stayed in a site with electricity and water. No sewer hook-up but there is a dump station in the campground. Great amenities including flush toilets and token operated showers. Each site has an ocean view. A bit of road noise from PCH but million dollar houses also have such problems! There is an elementary school adjacent to the campground so you get a few PA announcements to start your day.
There is a small visitor's center on site. Hiking and mountain bike riding are in the canyon adjacent to the campground. You can access the beach by walking down the hill and using the tunnel under PCH. From there, you can walk to Crystal Cove Historic Site and the Beachcomber restaurant. You can also walk to a nice chopping center with restaurants and a Trader Joe's (we forgot toothpaste). Your campsite parking pass is good at any of the parking areas in Crystal Cove State Park so you don't have to walk if mobility is an issue.The beach is clean and great for beachcombing - just can't collect anything. Lots of marine and land wildlife in the area.
Close to Laguna Beach so you can go into this nice artsy community.
A couple of other reviewers mentioned a few things that seem a bit inaccurate. Alcohol is limited to the campsites but you can drink in your campsite. You just can't take it to the beach or to the bluff overlook. It is easy to get in and out - unless you are in one of the backcountry sites. Pelican Hill Resort and golf club are nearby (not Trump National which is in Palos Verdes).
