Nice place for a run, the paved "track" around the field in front of the amphitheater is right at .5 miles. It's nice to string together 2 or 3 laps around the trail with a lap around the paved loop in between. Enjoyable anytime.
Very short trail I think it's less than 2 miles. Short distance is good for my little dog. Grounds people didn't seem to mind both of my dogs off leash. Not a trail if your looking for long workout. Short, sweet, simple and great for dogs.
