There's a lot going on at this park, including a skate park, swimming pool, softball fields, and Norfolk's largest playground. So if you're already going to the park, bring your bike and enjoy a nice ride around the perimeter. It's a short trail with lots of potential for expansion.
I don't think anyone officially maintains the trails here. This outer loop is the one that people still walk, ride, or run, so it's the only one currently navigable.
