O'Neill Regional Park's 4,000 acres are situated in beautiful Trabuco and Live Oak Canyons. The park is heavily wooded with coast live oak and sycamore trees. The hillsides surrounding the park are filled with cactus, wild buckwheat, sagebrush and chaparral of scrub oak, buckthorn and mountain mahogany. Trabuco and Hickey Creeks also meander through the park, flowing in winter and early spring, dry in summer and fall.

Gold Spotted Oak Borer (GSOB), an invasive beetle that has killed thousands of oak trees in San Diego and Riverside counties in a short span of time, has now been detected in Orange County. The GSOB was discovered in approximately 60 trees on County park land in northern Orange County. Since GSOB is transported in oak firewood, it is critical that Californians keep firewood local and not move it out of the area.
OC Parks is pleased to introduce new parking passes that will allow visitors to use a single card to park at all County regional and wilderness parks and/or beaches.
The new “smart cards” replace the entry cards and stickers that were previously used for annual parking. Unlike the previous OC Parks passes, which were fixed to a calendar year (January through December), these smart cards are valid for 12 months from issue date and can be renewed annually. Moreover, for wilderness and beach locations which previously required a sticker affixed to a visitor’s windshield, these passes can be used with any vehicle. The price for the new cards remains the same as 2014.
The clocks fall back early Nov. 2, marking the end of daylight saving time and OC Parks’ spring-summer operating schedule. Wilderness parks close at sunset and most regional parks close at 6 p.m. for the fall and winter.
Making Orange County a safe, healthy, and fulfilling place to live, work, and play, today and for generations to come, by providing outstanding, cost-effective regional public services.
