Ralph B. Clark Regional Park

Ralph B. Clark Regional Park is a 104-acre green space in Orange County stretching along Rosecrans Avenue. The site features open grass areas, native plant hills, and sandstone cliffs that shape the northern landscape profile.

The site originally opened in 1981 as Los Coyotes Regional Park and received its current name in 1987 to honor retiring Orange County Supervisor Ralph Clark. This name change marked a shift in management and a stronger focus on science education.

The Interpretive Center houses a paleontology museum where visitors can watch scientists preparing fossil specimens for study. The exhibits tell the story of prehistoric life in this region and help people understand what Orange County looked like millions of years ago.

The park is easy to explore on foot, with different paths winding through grassy and planted areas. Access to the lake and amphitheater is straightforward, though some spots are hilly and require steady walking.

A three-acre lake within the park grounds allows fishing activities and offers a quiet spot for visitors. Positioned directly above the water, the amphitheater provides an unusual backdrop for outdoor performances.
