Immediately out of both parking areas, trails are a wide, flat, gentle mix of dirt and gravel. Within a couple-three minutes, they lead to rocky, rooty, up-and-down singletrack loops that cross streams and marshy areas via boardwalk, then loop through what must be one of the nation's most-beautiful urban forests. Experienced Hartley riders will know that within those loops are sections that are accessible to beginner mountain-bikers. Most Hartley riding is intermediate to expert. Many dog walkers, runners, and their dogs also use the trails, which are multi-directional, so stay alert for traffic.<br />
