O'Neill Regional Park is 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.
The park serves both as an overnight camping and day use/picnic facility.
Picnic areas vary in size and are available on a first come, first served basis or by reservation. Barbeques and picnic tables are available throughout the park. Call the park for more information.
More than 23 miles of scenic trails can be explored by foot, bicycle or horseback. Other day use activities include horseshoe pits, two large community turf areas and a children’s playground.
The Arroyo campground offers 79 campsites varying in size to accommodate RVs or tent camping for up to eight people per site. Reservations for individual sites can be made online, by phone or in person. The park offers eight large group campsites for parties of 17 or more and five equestrian campsites, each equipped with horse corrals, barbeques and fire pits. Reservations for groups of 17 or more can be made by calling the park office at (949) 923-2260.
