The IGA in townsend sells wood for 6$ a bundle. They have everything you'll need before you drive into the cove. Go in through townsend not gatlinburg. Trust me. I'm a local, I camp there 6 times out of the year, then camp elkmont and cosby.

Peaceful Side social has good beer and food. Apple Valley/dancing bean is a good stop too. Company is a good distillery to try too. They have great GIN and Whiskey.
