Ralph B. Clark Regional Park is nestled at the foot of the Coyote Hills. The 104 acre property extends north and south of Rosecrans Avenue with the softball complex. The park lands range from large open grass areas, to gently rolling hills of native plants, to sheer sandstone cliffs to the north.
A variety of recreational activities are available at Ralph B. Clark Park. These include large shaded picnic areas, hiking and biking trails, and children's playground areas. Team sports enthusiasts can enjoy spacious play areas including two sand volleyball courts, three softball fields and a baseball diamond. Children of all ages can enjoy fishing in the stocked three acre lake. Four tennis courts are located within the park and an amphitheater which overlooks the lake, is ideal for outdoor plays and recreation programs.
The Interpretive Center, which opened in September of 1988, contains a paleontology museum that provides an educational view of prehistoric Orange County through exhibits, programs and guided tours. Also the opportunity is provided to watch scientists and volunteers excavate and prepare fossil specimens for study and educational exhibits.
Fall trout stocking was delayed due to a disruption in the supply chain.
In early 2020, multiple California trout hatcheries were infected with Lactococcus garvieae, a bacterial outbreak similar to streptococcus. California Department of Fish and Wildlife (CADFW) was forced to euthanize millions of trout, which will impact inland fishing for many years.
OC Parks has been working with our lake management contractor to secure necessary permits and import Rainbow Trout from a hatchery located in Idaho. The first trout stockings are anticipated to take place the week of Dec. 7-11. The full stocking schedule will be posted as soon as it is finalized.
UPDATED 1/6/21: In an effort to minimize the impacts of coronavirus (COVID-19) on park patrons, staff, and the Orange County community at large, and consistent with the guidance provided by the Centers for Disease Control and Prevention (CDC), Governor’s office, the Orange County Board of Supervisors and the Orange County Health Care Agency (HCA), OC Parks are operating in the following manner.
**Revised 2/18/20 Upcoming trout stocking schedule by week for Irvine Lake, Carbon Canyon Craig, Clark, Tri-City, Irvine, Laguna Niguel, Mile Square and Yorba regional Parks.
California fishing license required* and all California Department of Fish and Wildlife rules apply. (*license not required at Irvine Lake)
The clocks fall back early Sunday, Nov. 1, marking the end of daylight-saving time and OC Parks’ spring-summer operating schedule. Most regional parks close at 6 p.m. for the fall and winter, and wilderness parks close at sunset. Make sure to check our COVID-19 information page for modified operations at some parks.
