Bommer Canyon

Bommer Canyon is the standout piece of Irvine's open-space network — a hidden coastal canyon south of Bommer Canyon Road that for decades was a working cattle camp. Today it's a managed open-space preserve with a mix of self-guided public access and Irvine Ranch Conservancy guided hikes, runs, and rides. The core trail system runs through oak and sycamore woodland in the canyon bottom and out onto exposed ridges with full panoramic views. Some trails require guided access; others are open self-guided during scheduled hours.
