Located within OC Parks’ Irvine Ranch Open Space, Red Rock Wilderness features more than 8 miles of new trails for hiking, mountain biking and horseback riding along with a scenic overlook that offers 360-degree views of the nearby iconic red rocks, Black Star Canyon Wilderness, Irvine Lake, Santiago Canyon and beyond. Additional 3 miles of multi-use trails within Loma Ridge Nature Preserve, part of OC Parks’ Irvine Ranch Open Space, will also be accessible for hiking, mountain biking and horseback riding. Multiple loop options that vary in distance and range from easy to moderate in difficulty are available for self-guided exploration.
Rain or inclement weather will cancel the program.
Please review our Trail Tips page and FAQ page to prepare for your experience in the wilderness area.
Do not stop or park anywhere along Santiago Canyon Road. The entrance gate will not open until 8am. Anyone stopped or parked along Santiago Canyon Road prior to the opening will be subject to citation. Thank you for your cooperation with regard to the safety of everyone on the road. Please plan your drive accordingly.
This is a natural area characterized by certain inherent dangers including: mountain lions, rattlesnakes, poisonous plants and insects, weather extremes, loose rocks and rugged terrain. The Irvine Ranch Open Space contains rare and sensitive habitat and is under strict protection. Participants are required to stay on designated trails at all times. OC Parks Rangers may issue citations for visitors found off-trail. For your safety, please stay on the designated paths during your visit to Red Rock Wilderness. To learn more about the staging areas and activity locations, please visit our Staging Areas Playlist page.
Other Important Notes:
OC Parks Rangers require all trails to be cleared for closure by 2:00 pm
No new trail users will be permitted onto the trails beginning one hour prior to closing.
Dogs are prohibited on the Irvine Ranch Open Space. By nature, dogs are predators; their presence and their lingering scent disturb the indigenous wildlife and disrupt vital routines long after a dog has left the area.
Minors, ages 17 and under, must be accompanied by a parent or guardian.
Adult mountain bikers are requested to wear helmets. Minors are required to wear helmets per state law.
Inclement weather or fire danger will cause the program to be cancelled.
Multi-use trail etiquette: Please remember that bikers yield to hikers when sharing the trails. Click here for more trail tips.
To minimize the human impact on wildlife and their habitat, there may be unannounced trail closures or the rotation of areas being open and closed. This is an adaptive management approach to accommodate both the human users and the wildlife needs.
