It's marked on the sign for perimeter but there are also shorter options. If you use a health app, it will tell how far you have walked and Samsung Health App is what I use for my android phone
It's marked for a 2 mile track. If you walk from the parking lot to and from the start sign, it's a little farther. My husband walks it twice for 4 miles.
It goes completely around the entire park- well inside the perimeter anyway. The park it's self is pretty big. If you pull it up on maps in Satellite view, you can see the perimeter of the entire park. I apologize for not knowing the exact distance.
