The Rangers are so very professional friendly and helpful. I highly recommend this campground. I've been visiting here always in an R.V. since I was a kid with mom and dad so many beautiful memories.

Great park for camping. We stayed for a couple weeks other than a couple days precautionary evacuation for flooding. Staff is helpful and knowledgeable. Houses are nice except for the first one as you come into the park is a bit dated. Beautiful area. The drive into the canyon can be a bit treacherous but just take it slow. Dumpsters throughout the park. Some sites also have water spigot at them. A lot of tent camping here also. We were in site 26. It was a bit snug. There are a couple corner sites for pull through for long RVs. Nice that each campsite has a picnic table also.

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.

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.
