Did you know that Bommer Canyon once was the site of an annual cattle roundup? Thousands of cattle roamed the Irvine Ranch throughout much of the 1900s. Each spring, cowboys rounded up the herd at the Bommer Canyon Cattle Camp – the ranch’s cattle headquarters. Now Bommer Canyon is permanently preserved open space – open for hiking, biking and even yoga under the old sycamore trees. (Visit www.irvinehistory.org for more Irvine history.)
