I'm in Knoxville and don't ride in Pigeon forge but did a organized ride there last year, English mountain challenge. http://www.englishmountainchallenge.com/ There are cue sheets for 26 to 100 miles. If you need maps, motionbased should have plenty of data on this ride, here's one http://trail.motionbased.com/trail/activity/2995577


If you would want to drive maybe 30-45 minutes, you could make it over and ride the foothills parkway. A very nice ride.

I'm sure there will be plenty of traffic everywhere! Good Luck.
