Peter's Canyon Loop

Options for parking: Citrus Ranch Park (Portola Parkway and Tustin Ranch Road), Peters Canyon Elementary School both towards the southern trailhead. Or the regional park parking lot off Canyon View Ave for the northern trailhead.As mapped here, the eastern portion of the southern loop is very strenuous (and a great workout). For a modified version, one can stay on the eastern part of the bottom loop to get to the lake loop and then follow back the way one came from. If you start at Citrus Ranch Park, that is approximately a 7-7.5 mile loop.
