Located in Luray, Virginia. Duh, right?! You'd guess there isn't much else nearby if they named the town for the caverns...or the caverns for the town...wait, which came first, the chicken or the egg?! Anyway, if you're interested in Shenandoah National Park, that's nearby so maybe it's en route to somewhere else you're already headed. They have a piano key that hits a stalactite that makes music via resonance. People actually get married in the cavern.
