We camped here 3 days/ 2 nights. Had a huge pull through site that was level and shaded. Water on our site was easy but no electricity. Hikes were easy to access but no dogs on the trails except the 2 trails. So limited dog friendly trails. We enjoyed the location and rangers were nice.

Wonderful place to camp! Clean site, clean bathrooms with showers, awesome Rangers, good amount of trees and open skies, and very stable concrete benches. Very nice spot close enough and far enough from the city life.

I had not been here for a couple of years. The campground, bathrooms and the showers were clean and well maintained. There seemed to be quite a few people that were temporarily living there out of necessity. The campground was almost completely full every night and empty in the morning. For the most part it was completely quiet at night except for the sound of people coming in late and pitching tents or getting their cars ready to sleep in. I wouldn't suggest leaving your belongings unattended for to long though.

Nice regional park. There is a funny homeless man who sits at the back of the park and yells funny stories. You have to check him out if you are there. I do not like how they added conststion cones in the trail to watch out for obvious low hanging branch. It takes away from the ambience.

One of my favorite local regional parks, bathrooms and showers if you need them. Lots of trails to explore, very kid friendly. And if you don’t want to cook your own meals there are plenty of options close by in Rancho Santa Margarita.
