This park has two entrances. I first parked and walked the Zion Road entrance. This is an easy flat trail that is maintained as a grass mown path through mostly meadow type terrain. I recall two gully type crossings.
The second entrance is along Route 108 and is primarily for horses. With no notice the loop is closed at the far end so you have to backtrack or follow the horse trail to the Zion Road entrance.
The Zion Road is the best choice for a quiet nature walk. Lots of birds & deer
Trail only goes for about half mile before reaching a gate then you have to turn back
