Arroyo Trabuco Trail

The Arroyo Trabuco Trail follows the bottom of the Arroyo Trabuco wilderness corridor — a long, undeveloped canyon stitching O'Neill Regional Park to Mission Viejo. The trail is mostly natural surface, with creek crossings, mature oak and sycamore canopy in shaded sections, and easy access from staging areas along the route. It's one of the calmest long-walk options in south OC, especially after winter rain when the creek runs.
