Did a long weekend hiking trip with a friend of mine from Delaware to Great Smoky Mountains National Park.  October is a nice month to visit because of the weather and Fall foliage but it is very busy time in general in the park.
Flew into Knoxsville, TN and drove out to Gatlinburg.
We hiked about 35 miles  over 3+ days.  Biggest ascent was around 3000 feet climbing to summit of Mt LeConte.
