Based on the map, this is the Oak Island Loop, but the loop is only around 3 miles, not 7. Regardless, it's a great place to see birds, butterflies and even some wildflowers in late May. But be wary of the cow pies and the poison oak, which is quite prevalent on parts of this trail. Also, right near the trailhead, take the dirt track to the left just before the main trail to visit WagonWheel Hole. It's a very peaceful little area and hardly anyone seems to knows about it.
