O’Neill Regional Park is a vivid and widespread recreational area located in the Trabuco and Live Oak canyons of eastern Orange County, California. This immaculate park has a surrounding of over 4,500 acres of parkland with stunning natural beauty. This park is also referred to as Arroyo Campground. It is pre-eminently known for its manifold landscape. Although its surrounding areas are covered with cactus, sagebrush, and buckwheat, this park is a wooded valley of live oak trees and sycamore trees.

The Park provides a tranquil escape from the crowd and noise of city life. Whether you’re looking for hiking, horseback riding, a family picnic, or an adventurous camping experience, this place is the perfect destination to experience the natural beauty while enjoying a range of recreational activities.

The O’Neill Ranch proprietors contributed 278 acres (113 ha) of land for recreational use, which led to the founding of the park in 1948. The park’s current size was achieved through several land purchases between 1948 and 1982. Numerous plants and animals, including the extremely rare poison oak, bobcats, and mountain lions, can be seen.
