Tour de Wolf features 6 miles of hiking trails near Memphis, TN.
"From the I-240 loop in Memphis, exit on Walnut Grove Rd. Go east on this road for apprx. 2 miles. After passing a hospital and high school the road will go over the wolf river and the scenery will become a little more "non-city". On the right you willpass a BMX track and a soccer complex. You will then see a stop light. Take a left and when the road splits immediately, stay right and go over a cattle grate. You'll pass some buffalo and bison on the left and a lake on the right. After the lake take a right(second right after the cattle grate). There is parking on either side of the ranger station. Once on your bike, take the blocked (to vehicles) road. After a tenth of a mile you'll see a trail head. It reads, "Tour De Wolf" and had an arrow. (that's the way to the trail)
