Bommer Canyon


Rich in both Irvine Ranch lore and nature’s wonders, Bommer Canyon beckons walkers, hikers, and all other outdoor enthusiasts to stroll past ancient oak and sycamore groves and rough rock outcrops. Much like the City’s Quail Hill Loop Trail, specific trails in this area are open daily for self-guided hikes from dawn to dusk; however, other areas within Bommer can only be accessed through guided programs and do require pre-registration. Monthly Wilderness Access Days are available to allow hikers and bikers the chance to explore the network of outstanding trails and views of the area.

A wide variety of activities are offered by the City of Irvine in partnership with the Irvine Ranch Conservancy. For a list of upcoming events in Bommer Canyon, click here.


** NOTE: Equestrians permitted from May 1 to November 30 only**

Construction Starts in Bommer Canyon Cattle Camp 

On Monday, March 1, construction will begin on the highly anticipated Bommer Canyon Cattle Camp Rehabilitation project. The  Cattle Camp area is undergoing upgrades and renovations to improve and update the event site and surrounding park grounds, a 15-acre site originally built in 1967. New facilities at Cattle Camp — a popular spot for community parties, picnics, weddings, and campouts — will match the park’s original ranch style. The project includes constructing new buildings including a “chuckwagon” building and stage, and providing new ADA accessible pathways.  A new waterline being brought to the property will allow for construction of a new restroom building.


Cattle Camp is closed to the public during construction, and access to nearby trails and parking may be closed intermittently throughout construction of the project, which is expected to be completed this year.  For additional information on the Cattle Camp project, visit
