Irvine Ranch Open Space

The Irvine Ranch Open Space spans 25,000 acres in the Eastern Foothills of Orange County and consists of protected wildlands, including six nature preserves. Named a State and National Natural Landmark, OC Parks stewards these special lands in close coordination with the Irvine Ranch Conservancy as a land management contractor and The Nature Conservancy, a conservation organization. Various educational and recreational opportunities are available through regularly scheduled programs only. When the County received the property, it did so with strict environmental protections already in place to safeguard its rare and precious natural resources. OC Parks continues to uphold the conservation obligations inherited with the property and balances environmental stewardship efforts with robust scheduled access opportunities.

Hiking, biking and equestrian activities within Irvine Ranch Open Space are accessible through monthly self-guided Wilderness Access Days or scheduled programs. Wilderness Access allows for self-guided exploration at your own pace. Docent-led guided access takes place in small group tours with engaging interpretation of site features. 

Parking is free and dogs are not permitted, except on Black Star Canyon Road.
