Discovered in 1878 and designated a Registered Natural Landmark by the National Park Service, these massive underground rooms tower 10 stories high and are filled with dramatic stone formations and glassy pools. You’ll enjoy a private tour along paved, well-lit walkways through this awe-inspiring landscape.
On the way, we’ll stop in Harrisonburg, VA for lunch at the crowd-favorite Grilled Cheese Mania, where you can order from a variety of creative grilled cheese sandwiches, including gluten-free and vegan options. (Lunch is not included in trip price.)
