Lurray Caverns, 101 Cave Hill Rd, Luray, VA 22835
Its a beautiful cave which stretches 1.5 mile takes about an hour and half to explore. Although the entry fee is ridiculously high (Adult-$28), still the place is worth it. Facility was clean, and there are tour guide at each point which gives brief info about the structures , when and how it formed.
The structures were cool and the pool of water that reflects the formation was awesome.Cave was wet and damp and need caution.Avoid touching the stalagmite and stalactite as it will slowdown its grow.
One can visit Car and Carriage Caravan Museum on way back, which comes as complementary along with admission ticket to caverns.
Caves tend to be cold, so dress warmly. The caverns were very unique and it's a one of a kind experience! I'd recommend you go visit!
