This is a mildly trafficked singletrack section of the Ice Age Trail. Park on the turnout for the Ice Age Trail on Hwy J. The trail runs parallel to the highway for a few hundred feet and then turns south, slowly climbing up a wooded hill. It then declines at a steeper but manageable angle.
The trail ends on Bilkey Road, 2.4 miles from the Lodi Segment. Unfortunately, road sections separate Fern Glen from the Lodi Segment to the south and the Gibraltar Rock Segment (2.2 miles) to the north.
