Bommer Canyon is a hidden gem located between Turtle Ridge and Shady Canyon in Irvine, California. Historically, the canyon played a crucial role in the cattle operations of the Irvine Ranch. While the cattle are no longer present, remnants of the cattle camp—such as several buildings, loading ramps, corrals, and equipment—can still be found.
This open space preserve is not just a historical site but also a haven for outdoor activities. With a variety of trails for hiking, biking, and seasonal equestrian activities, it’s the perfect place for a day of adventure. The diverse landscape, featuring oak and sycamore groves, coastal sage scrub, native grasslands, and rock outcrops, provides a scenic backdrop for your outdoor escapades.
Bommer Canyon History
Historically, the area was part of Rancho San Joaquin, established in 1837, and later became the hub of the Irvine Company’s cattle operations from the late 1800s to the 1970s, centered at the “Bommer Canyon Cattle Camp.” Today, the 15-acre Cattle Camp has been restored with a rustic design, featuring a sycamore canopy, picnic areas, a stage, and modern amenities, including a chuck wagon kitchen. It’s available for private rentals for events such as weddings and picnics, and hosts community activities.
Boomer Canyon Nature Garden
Adjacent to the Cattle Camp is a small but intriguing garden featuring colorful signage that tells the story of the camp while highlighting native plants and animals. The Bommer Canyon Nature Garden, open daily, showcases relics from the former cattle ranch.
