Caves are extremely fragile environments, often only resulting in thousands of years of little disturbance. For that reason, caves that are discovered and unprotected can often receive significant and permanent damage from unregulated use. Across the nation, to connect people with the underground world beneath their feet, there are several “show-caves” that not only provide safe access and guided tours of these subterranean environments, but help protect all the stunning speleothems and features they encompass. Whether you are looking for an introduction to caving, or you want to crawl and squeeze your way through a wild cave tour, from beneath the roots of Sequoia National Park to the Cumberland Gap of the Appalachian Mountains, and so many in between, there are enough show caves to explore to stay underground throughout the year. For more information on other show-caves around you, a great resource to start with is the National Caves Association website.
Know Before You Go:
White-Nose Syndrome (WNS) has been documented in caves across the nation and is detrimentally effecting cave-dwelling bat populations. While WNS isn’t noted to harm the human population, it can easily be spread by humans, making it another consideration before visiting a cave. Wearing appropriate clothing that hasn’t been contaminated by previous cave visits and taking the time to Learn More About White-Nose Syndrome can help make your next visit to a cave a fun one for everyone and everything involved.
Mammoth Caves National Park, Kentucky
There are more than a handful of show caves to discover in Kentucky, but none compare to the extensiveness found in Mammoth Caves National Park. With over 400 miles of this subterranean atmosphere already explored, and many passageways still waiting to be discovered, visitors to Mammoth Caves State Park can receive a wide range of tours of this underground space, including lantern-led expeditions and a kids-only “Trog Tour”. Reservations aren’t required but are extremely recommended, especially on holidays and weekend events. The many different tours offered by Mammoth Caves National Park all range in difficulty, price and time spent underground, but each provide outlets to explore this incredible natural wonder in a way that is both safe for you and the environment. Upon your visit, if you decide the underground life is not for you, Mammoth Caves also offers over 70 miles of hiking trails above ground, including four self-guided tours to help you learn more about the world underneath your feet.
Crystal Cave, Sequoia National Park, California
While there is a lot to see at Sequoia & Kings Canyon National Park aboveground, a fascinating world awaits below for those who want to see it. Not far from the Giant Forest in Sequoia National Park, Crystal Cave is a marble cavern full of fragile resources of which can only be seen on a guided tour. Partnering with the National Park Service, the Sequoia Parks Conservancy provides tours of this spectacular underground space through the spring and fall. Tours range from Family Tours on flat surfaces to Wild Cave expeditions where you’ll get a little dirty. Accessing the entrance to Crystal Cave is an adventure itself, and because of its wilderness location, the cave can close unexpectedly at any time, making for reservations and back-up plans a recommended plan of action.
Gap Cave, Cumberland Gap National Historical Park
Located at the border of Virginia, Kentucky and Tennessee, the Cumberland Gap has been a significant location for pioneers, travelers and explorers for centuries, and still today this culturally iconic swath of land holds a lot to discover. There are many caves in this now nationally designated historical park, and a handful that are open to the public including the backcountry Skylight or Sand Caves. To get the most out of an underground experience at the Cumberland Gap, guided tours are available for perhaps the area’s most dazzling cave system, the Gap Cave, formerly known as Cudjo’s Cave. There is only one guided tour option available for the Gap Cave, which involves a 1.5-mile route that is accommodating for most members of the family, and includes insight on the different environmental factors that created the grand underground cathedral that is the Gap Cave.
Wind Cave, Wind Cave National Park, South Dakota
Sitting below the intact prairie landscape of the Black Hills National Forest in western South Dakota, Wind Cave provides a stark contrast from the world above it. Constituting as one of the most complex caving systems in the world, Wind Cave is still being actively explored by experts today, and to get a taste of this wild environment, guided tours are offered 362 days of the year. With a wide range of tour options available to meet the need of all kinds of adventurers, every guided outing into the cave sheds some light on the unique arrangement of features that make Wind Cave so unique. Specifically, the formation of the honeycomb-like Boxwork formations in Wind Cave is perhaps the most intricate display of this fragile speleothem found anywhere else in the nation.
Carlsbad Cave, Carlsbad Caverns National Park, New Mexico
Consisting of more than 119 caves, Carlsbad Caverns is a world-renowned caving destination that plummets visitors deep below ground underneath the Guadalupe Mountains of southeastern New Mexico. While it might be a little warm above ground throughout the summer months at this southwestern hotspot for adventure, the caves below ground always remain around 56 degrees, making them a year-round destination. Self-guided tours are available to the public to gain access to the “Big Room”, but the recommendation course of action is to reserve your spot on one the many guided tours that can take you into the caves further. The most popular guided experience is the King’s Palace tour, which explores four different chambers all decorated with a wide variety of cave features in an hour and a half. Longer tours are available sporadically throughout the week, and reservation are always recommended.
Luray Caverns, Luray, Virginia
Located in Virginia’s Shenandoah Valley, the Luray Caverns were first discovered by modern civilization nearly a century and a half ago, and since then, this cathedral of caverns has become one of the most popular spots to explore underground in the Eastern United States. With 10-story high ceilings and a 47-foot column, the sheer enormity of Luray Caverns is almost hard to believe with your own eyes, even with the many lights installed to help you find your way. Guided tours come provided with every admission into Luray Caverns, and visitors can expect to see more calcite formations than they’ll ever see again in their life. With the admission into the cave, patrons can also spend time on the self-guided tour above ground of the Luray Valley Museum and Car & Carriage Caravan.
“The Cave State”, Missouri
With well over 6,000 caves in the state of Missouri, the people at the Missouri Caves Association have coined the term “Cave Factory” for the many continuing geological processes happening beneath their feet. It’s the karst areas of the Ozarks that lend to so many caves, and over thousands of years these once spring-fed areas have morphed into the colossal caves they are today, many of which you can explore with some helpful guidance. Fantastic Caverns offers America’s only ride-thru caving experience via jeep-drawn trams, and Talking Rock Cavern near Silver Dollar City has been touted as Missouri’s most beautiful cave. Whichever Missouri cave system you choose to explore, you’ll be treated to a unique underground experience with each visit.
Kartchner Caverns State Park, Benson, Arizona
Located in southern Arizona, Kartchner Caverns have been developing for thousands upon thousands of years, but was only discovered by modern civilization in 1974. With conservation efforts in mind, Kartchner Caverns wasn’t introduced to the public for over a decade after its discovery, once the landowners reached an agreement with the state to make this geologically significant area a protected state park. The two main rooms that are currently available for public tours include the Rotunda-Throne Room and Big Room, which both offer unique formations like 20-foot soda straw stalactites, birds nest needle formations and “Kubla-Khan”, Arizona’s largest known underground column. Much of the Kartchner Caverns are wheelchair and limited-mobility accessible, making these southwestern caverns fun for everyone to enjoy.
Natural Bridge Caverns, San Antonio, Texas
Like many things in Texas, the Natural Bridge Caverns located just outside of San Antonio are big. In fact, this popular tourist destination is the largest show cave in the state, and with open availability year-round to explore this geological wonder as part of a guided tour, there’s little limit to the amount of exploration to be done at the Natural Bridge Caverns. With four different types of tours available, ranging from lantern-lit to hidden passageway exploring, whatever type of cave experience you’re looking for, Natural Bridge Caverns can provide the guidance needed to have a great time.
