This is an easy, contour-following singletrack through the park's grasslands. It has outstanding views of the Carquinez Strait area (including the refineries and the Carquinez Bridge). In the spring, it is a great trail. In the summer, it is likely to be either baking hot or freezing and very windy.
You access the trail from the parking area by following the Edwards Loop Trail clockwise to the top of the hill, turn right and go about 50ft. to reach the tunnel under the Cummings Skyway and the start of the trail.
