Bommer Canyon Preserve is a 385-acre natural open space offering scenic hiking trails, historic ranch sites, and diverse wildlife habitats within the Irvine Ranch Natural Landmarks in Southern California.
Bommer Canyon Preserve is located in the city of Irvine, Orange County, California. It protects approximately 385 acres of coastal sage scrub, oak woodland, and riparian habitat, making it a vital piece of the larger Irvine Ranch Natural Landmarks. The preserve encompasses rolling hills, seasonal streams, and rocky outcrops that provide a refuge for a variety of native plants and animals including mule deer, bobcats, and numerous bird species. Historically, Bommer Canyon was part of the Irvine Ranch and contains remnants of ranch operations dating back to the early 1900s, including old ranch roads and rock corrals. Access to Bommer Canyon is controlled through guided hikes and programs administered by the City of Irvine, reinforcing its status as a protected space focused on both recreation and conservation. Visitors typically enjoy hiking, trail running, and wildlife viewing on the well-maintained multi-use trails that traverse ridges and canyon floors offering picturesque views of the surrounding Santa Ana Mountains. The preserve's quiet and less crowded atmosphere compared to other Southern California parks enhances its appeal to outdoor enthusiasts seeking nature immersion near an urban area. Seasonal wildflower blooms, especially in spring, add visual interest, while occasional ranger talks and interpretive events provide educational opportunities. Bommer Canyon plays an important role in preserving the natural and cultural heritage of the Irvine area and supporting regional biodiversity.
