Irvine 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, shaded turf areas provide a serene setting for leisure activities. Santiago Creek bisects the park and a pond with stone-work waterfall and foot bridge is located in the center of the park. The variety of landscape greatly enhances the park's beauty.

Tables and barbecues are located throughout the 477 acre park with convenient parking and restroom facilities nearby. A paved bicycle/walking trail meanders through the central park providing easy access to six playgrounds, four softball fields, two horse shoe pits, volleyball courts and lagoon.

A four mile equestrian trail skirts the perimeter of the central park providing scenic views of the park and it's natural scenery. Horse trailers can be parked on the north perimeter of the train station parking lot. A lookout trail is on the north slope of the natural area where a covered shelter, watering trough and water fountain are available.
