Snacktime and I are heading for an exploration of Virginia. Of course it will involve hiking the trail (and in different sections to get an idea of all of the state). But we're also planning on doing some other educational sightseeing, and could use some opinions. We'd like to see some caverns, and I've narrowed it down to Luray, Shenandoah, or Natural Bridge. Any opinion on which would provide: best educational experience, most fun, easiest to access from trail, lodging that is not ridiculously expensive (hostel or camp works for us). Our trip will be mid-late Sept, weekday (unless FarmerChef would like to join us with his kids, then weekend if necessary).
Any opinions?
