SaveIrvine Regional Park is nestled among a grove of heritage Oak and Sycamore trees. The rolling foothills surrounding the park are filled with a variety of wildlife. Trees and shaded turf areas provide a serene setting for leisure activities. Santiago Creek bisects the park and a pond with a stone-work waterfall and footbridge is located in the center of the park. The variety of landscapes greatly enhances the park's beauty. Remember to visit the OC Zoo inside the park.
