Hi Brian,
I'm a local photographer, and love the colors around these mountains....Around the 21st, the colors will be down low..........The Smokies will still be fantastic, but the colors will not be on top of the mountain...........Chances are they will be gone.........You can get good shots half way up the mountain, and around Gatlinburg.....
Go up Highway 321 into Gatlinburg, and there are some good places to visit.......About 10 miles out of Gatlinburg, is Greenbriar.......cuts off Hwy 321 to the left.......It's part of the national park, with streams and good colors.......
When you get into Gatlinburg, go to traffic light #8, turn left, and stay straight. It takes you into the motor nature trail.....a one-way paved road about 8 miles long with old log cabins, streams, a mill, and waterfalls right beside the road.....brings you out right back into Gatlinburg.....
There are hiking trails in The Smokies, it's according how long a hike you want to take......One of the shortest hikes is the Laurel Falls hike, and a beautiful waterfall..............
That's a few good places to get colors that time of year.......
Good Luck to you and I'll see you on the mountain.
