Whiting Ranch Wilderness Park encompasses approximately 1,600 acres of Riparian and Oak Woodland canyons, rolling grassland hills, and steep slopes of Coastal Sage Scrub and Chaparral. The park is highlighted by scenic rock formations, including the beautiful Red Rock Canyon. There are three intermittent streams: Borrego, Serrano and Aliso Creek meandering through the park, each hosting an abundance of wildlife. Remnants of the former cattle ranching days can been seen throughout the park.

Activities

The park is crisscrossed by 15 miles of graded roads and single-track trails, providing excellent opportunities for hikers, mountain bikers and equestrians. The Red Rock Canyon and Billy Goat trails are reserved for hikers only.

The McFadden Ranch House, park office and interpretive center, features a trail rest stop for the Aliso Creek Regional Trail, cultural and natural history exhibits, and park information.

Nature walks for school and community groups are available with advanced reservations; Group size and tour days are restricted by staff availability. Minimum size: 10 people.

History

The properties now known as Whiting Ranch Wilderness Park and the Foothill Ranch community have associations with several pioneer Orange County families. In 1842, Jose Serrano was granted 10,668 acres of land known as Rancho Canada de Los Alisos. Serrano and his sons raised crops to sell such as corn, beans and watermelons. However, their principal industry was cattle, from which hides and tallow were sold. Unfortunately, the drought of 1863 and 1864 caused the death of Serrano's herds, forcing foreclosure of the ranch to Los Angeles banker J.S. Slauson and Associates. Slauson divided the ranch into ten parcels, the largest being 10,000 acres. The property was then sold to Dwight Whiting in 1885. Whiting encouraged the development of El Toro by subdividing level land, bringing the railroad through, and by planting olive trees, grape vineyards and some 400 acres of eucalyptus trees. This area is now known as Lake Forest. However, due to the arid climate and poor soil, agricultural use was unsuccessful. In 1959, the Whiting properties were sold to V.P. Parker and Associates, and residential development has since ensued.

In July of 1988, approximately 1,200 acres were dedicated to Orange County to be preserved as an open space wilderness park. Since then additional acquisitions have enlarged the park to approximately 1,500 acres. An additional 87 acre parcel adjacent to El Toro Road just south of Cook's Corner, known as the McFadden Ranch House, houses the park's office and interpretive center. The house was built in 1915 by James McFadden for two purposes. One to provide housing for the ranch foreman and his family, and the other to utilize the ranch more fully for farming and livestock pasture.
