ONeil is a great little park that’s tucked away among the urban sprawl of Orange County. Once in the park you feel like you’re far out in the wilderness. It makes for a great weekend great away. The park is well maintained and has 78 sites to choose from. There’s a general store nearby but its stock is limited. There’s also Trabuco Oaks Steakhouse across the street if you get tired of cooking. There are a number of trails in the park for hiking and mountain biking. Overall it’s a great park.
