I'll be camping with some relatives at Great Smoky Mountains National Park in mid/late October. I've heard that, at that time of the year, it is the most visited NP. Oh well, I've done Yosemite and Yellowstone in the summer, so maybe I'll be able to handle it!

Anyway, we have two nights (Monday, Tuesday) at Elkmont campground, two more (Wednesday, Thursday) at Cade's Cove CG. Any advice on things to see and do, preferably with the minimum amount of driving, would be appreciated. Unfortunately, my wife is in great cardiovascular shape, but hiking downhill causes her a lot of knee pain, so shorter and more level is better in terms of hiking. We'll have bikes, but I get the impression that biking right in the park is not really a viable option.

Thanks in advance for any help.
