What is the best 30 mi. or so loop you could offer in the Smokies: looking for a more difficult trail, particularly one that includes ridge walking and river side camping--ascent and descent); planning on two nights.

Thanks,

P.S. Heading out Saturday (Nov. 18), so the sooner your advice the better!
P.P.S. I only chose Cades Cove because it wouldn't let me choose 'Hiking'. Anywhere in the Smokies is fine.
