Reviews Photos Tracks Krystal Harte (126) 12 months ago N/A: 20 Completed 1 Reviews I've hiked the 2.9 mile stretch through Rockwoods Range several times, and it's a great workout. The trail doesn't loop, so it's a total of nearly 6 miles when you turn around to get back to the parking lot. There are a lot of fairly steep hills/valleys and it's uphill most of the way. It usually takes me 2.5 hours to hike this portion of the trail. It's not very well maintained, so there may be fallen trees over the path, and in the summer it can be overgrown. Don't forget the bug spray! Charles Mcdonald (1119) over 2 years ago N/A: 21 Completed 20 Reviews This 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 Scarbrough (223) over 2 years ago N/A: 5 Completed 2 Reviews THIS 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.
