Wildwood Regional Park, Regional park in Thousand Oaks, United States.

Wildwood Regional Park covers 1,765 acres in the western Simi Hills and Conejo Valley, with 27 miles of trails. Its terrain includes volcanic outcrops, the year-round Arroyo Conejo creek and two waterfalls, coast live oak and valley oak woodlands, sycamore-lined creek beds, canyons, steep hills and grasslands. Habitats range from oak woodland to chaparral, coastal sage scrub and freshwater marsh.

The land was ancestral territory of the Chumash people for thousands of years before becoming part of a Spanish land grant in the early 1800s. The area later served as a filming location for major Hollywood productions throughout the mid-20th century.

The park was used as a movie ranch, Janss Conejo Ranch, from the 1930s to the 1960s. Westerns and television series were shot here, among them Bonanza, Gunsmoke, The Rifleman, Wagon Train and Flaming Star. Filming still happens occasionally for television series and commercials.

The park has multiple entry points and parking areas accessible from towns surrounding the region including Thousand Oaks, Newbury Park, and Moorpark. It's best to bring water and wear appropriate footwear, as trails vary in difficulty and sun exposure.
