ReviewsPhotosTracksCharles Mcdonald3 years ago21 Completed20 ReviewsThis trail has been lengthened by approximately 4.5 miles. If you like long walks through the woods, this is a great trail. Non of the hills were overly steep, and were well graded, with plenty of switchbacks. This trail recieves a moderate rating in difficulty as none of the terrain was overly difficult, but the length of this trail makes it more difficult than moderate. This trail would make a great bike ride. GORC was actually there working on the trail when I hiked this. Mike Scarbrough3 years ago5 Completed2 ReviewsTHIS IS NOT A BEGINERS TRAIL!!!! I have completed this trail many times with the Boy Scouts and once without them, it is a moderately Difficult trail. lots of hills,(first one is a killer!) but a very nice walk thru the trees(99% wooded) of Rockwoos Range, Greensfelder park(behind Six Flags) and Rockwoods Reservation. There is water at the mid-way point at Greensfelder park,and the trails end, depending on the time of the year. Parks shut the water down in the winter months. You will need to have a couple cars with you when you do this hike! the trail head is at Fox Creek just west of Six Flags on the outer road, There is parking at the midway(Greensfelder Park) if you want to complete a shorter hike, But the Trail ends at Rockwood Reservation Education Center, Lots of parking there. There is also Picnic Areas with restrooms (outside)in Greensfelder and at Rockwoods Reservation. Works great if you have to sit and wait for your cars to shuttle from one to the other.
