O'Neill Regional Park is amazing. Weekends fill up fast since it's a small drive from the hustle and bustle of Orange county life. It's a fun place to escape and feel a little more "wild..." The rangers and the attendants at the front gate are super nice and friendly. The campground is super clean and we'll maintained. Bathrooms and showers are clean and lots of hiking trails to choose from. After the holy jim fire you cant get up to the waterfall but there are other options around.
