Nice park. Mostly for tenters. Only one section accommodates any RV/Trailer longer than 20 feet. The views from some sites is great, most do not look over the ocean. The campground is up high above the beach with trails and stairs down to the water. Overall a nice place to get away for a weekend.
The beach here is beautiful. If you are lucky enough to get a spot (they book up 6 months in advance), enjoy the ocean. The sites are nothing exciting, very old pavement, more like gravel and no hookups, dump station, etc. There is a great bike path that goes from Refugio State Park to El Capitan State Park about 2.5 miles away that has beautiful views.
This place would be good except for all the flies, excessive oder from the cow farms, people walking through your site, and the excessive heat in the summer. If you there in the winter, and the weather is all right, it's a nice place to stop for a couple of days.
