Located in Majestic Trabuco Canyon, this expansive park offers a unique spot for both day use and camping. Life’s hectic pace slows noticeably when you enter the tree-shaded grounds. The feeling is remote, rural, relaxing.

Approximately 4,000 acres of deeply forested canyons, scenic rock formations and grassy rolling hills are enriched by intermittent streams and trails to create an ideal open air opportunity for hikers, mountain bikers and equestrians. The park’s interpretive center features a trail rest stop, cultural and natural history exhibits and park information.

The Arroyo Trabuco addition to O'Neill Regional Park is 935 acres of relatively pristine land. Presently maintained as a wilderness preserve, the Arroyo Trabuco is exemplary as a natural area where the rancho days are not far gone and where Golden Eagles, Mule Deer and Mountain Lions still exist.
