Luray Caverns

The easiest richly decorated cave on this list. Luray is packed with dripstone, and the whole route is 1.25 miles of well-lit paved walkway that most people cover self-guided in a little over an hour. The entrance is step-free and takes wheelchairs, although the caverns do not describe themselves as fully accessible, so call ahead if mobility is a concern. It is a classic commercial show cave, complete with the Great Stalacpipe Organ, so expect crowds and a polished feel rather than wildness. The trade-off is comfort: a constant 54°F that feels warmer in the high humidity, no climbing gear or fitness needed, and an early guided Discovery Tour each morning for anyone who wants the history from a costumed 1870s explorer.
