There's a place called The Worley's cave near Watauga it is a few miles deep, it is owned but you give the guy $5 he will lend you the key that lets you through the Caged entrance. And you can go without a guide.
i would not recomend it because you may get lost
When we went the only option was with a guide as it is very dangerous to go caving without a knowledgeable tour guide.
Appalachian Caverns requires a guide. But in addition to the tours, you can go on cave dives.
I think yes maybe, but you'd have to sign a waiver.
