A 6-mile mountain bike trail rambles through the hills east of the Davis Hollow Marina. It has very steep rocky sections and is definitely not a novice trail. The park cautions that it is for experienced off-road riders in good physical condition who are equipped for off-road riding. It’s not our kind of riding, and it’s noted here only because it’s close by. One trailhead is on Mt Union Rd about a third of a mile north of North Shore Dr, and there are two others on Alexander Ridge Rd.
