There is a little over 5 miles of combined trails consisting of four colors which are red,blue,orange and yellow. There are several intersections for creating a variety of routes and some can be moderately strenuous. Since the words like strenuous, moderate and easy are quite subjective I use the terminology rather loosely. Since the park is limited to under 200 acres most hikers average completing their hikes in 90 minutes. I hope this helps and one can call the ranger station (828)324-8461 to speak with a ranger or leave a message for a return call.
Almost 6 miles, if you do several trails.
