Devil's Racetrack is a formation of two rock 'fins' that stick out of the side of the mountains along side of I-75 just North of the 134 exit in Caryville. They are all very solid rock, nothing is very brittle, but the thing you have to look for is vegetation. Moss is really bad on several spots. Other than that the rock is spectacular. Great views on top of great climbs. The bolts are all really well placed, and anchors are very solid. The approach trail is a tad steep in some spots, so be careful if its wet out. The routes range from 5.3 to 5.9 on trad and 5.8 to 5.11 on sport. So there is stuff for everyone.
Take exit 134 on I-75. From there drive to Cove Lake State Park. Go past the entrance to the park, and take the next left. Follow this road until it intersects Butter and Egg Road. Continue through the intersection. After about a quarter of a mile, you will see a New house with a RED TIN ROOF. Turn left down the gravel road directly BEFORE this house. After less than a minute, you will see a gravel road on the right blocked off with big boulders. Park here, and hike up the gravel road parallel to the creek for several minutes until you see a easy place to cross the creek to your right. Once you cross the creek follow the paths upto the nose of the main spire. Everything to the left of the nose is the north face, everything to the right is the Alley.
Finally headed up to this crag after over a year of beta hunting. Honestly I was mostly worried about some chump tossing a rock through my windshield, as I have read more than one vandalism warning. No issues, easy to find, right on the Cumberland Trail. Parking is limited, room for maybe 6-8 trucks. 10 minute approach to moderate creek crossing, then a steep but short trail to the base. Trail marked by white blazes until creek crossing, then marked with black plastic on trees. Not sure what routes are what yet, was able to climb 2 lines, one free and one with gear. Very scenic, exposed. I'm guessing this will be a bushwacking nightmare in the summer, mountain laurel already growing like mad.
The road that you actually turn on(right by the newer house with the red tin roof) to park, you will see the boulders blocking the access to the Cumberland Trail, but there are no signs, just some spray painted boulders.
As for directions, the trail that leads across the creek to the cliff-line is approximately 100 yards past the first small waterfall. Yes, there is a tree across the river with a black plastic bag wrapped around it. Take that trail up a steep slope until you hit the first cliff-line, which I'm assuming, though not sure, is what the DCA calls the "lower wall." If you keep scrambling up, you will walk directly into the Main Flake (North Face), with the South Face (The Alley) on your right. I took a few photos of the parking area and creek crossing to help.
My personal opinion on the place is that it's a better winter destination. In the warm months, this place is a jungle, not to mention the presence of lots of bees (Lucy in the Sky).
Before heading there, did some effort trying to decipher the instructions above and comments below so I wouldn't waste time getting lost. I'm fairly confident the GPS coordinates of the parking lot are
Tried to find this today. If you get to the wooden bridge, you've gone too far, but you will end up on top of a mountain. I did not see the black plastic bag and so didn't find the wall. I'll have to try again in the future.
Yes, the black plastic bag wrapped around the tree is no longer there. From the main trail from the parking lot, after about 100 yards, look to your right and you will begin to see glimpses of the lower wall. Start looking across the creek for the trail that leads to the main wall climbing area, it's faint, but visible.
