Families looking for a great summer vacation are increasingly considering the excitement and romance of exploring the American West. With airfare and destination resorts generally priced beyond the average family budget, traveling by car or mini van and camping out under the stars is an immensely satisfying alternative.
For many families, touring national parks, monuments, national forests and state and federal lands provide an opportunity to see America’s spectacular natural attractions.
A part of the American West that is less visible, yet equally as awe-inspiring and thrilling as Yellowstone and the Grand Canyon, are the region’s commercially-operated caves. These ancient natural attractions are expertly-developed, providing a safe opportunity to enter the weird and unexplained underground worlds hidden beneath our feet. Seeing the mountains from the inside out provides a fresh perspective on the geologic processes that shaped the West.
Increasingly sophisticated in their public presentation, many of the commercial caves of the Rockies have invested in new electric lighting systems, recruited and trained competent guides, opened new chambers and passageways, and added kid-friendly attractions, such as sluice boxes, climbing walls, and sandbox digs for gems and fossils. Although corny jokes and entertaining banter from guides may have served a purpose in an earlier era, many of today’s public and private caves tours more resemble nature hikes with knowledgeable naturalists. New lighting, too, eliminates the colorful electric lights that brilliantly illuminated many of the caverns in the 20th century, and instead emphasizes their natural darkness and mystery.

Adventure is Underground
For many children, descending deep into a cave is a thrilling experience. Leaving behind the sunlit world, children are intrigued with the darkened underground passageways and the unknown. How far might these caves extend? What life might be found within these passages and chambers? How did these caves form? Is there any gold, treasure or bones within these caves?
A great start for your speleo touring vacation is the National Caves Association. A professional association of the majority of America’s commercially-operated caves, the NCA’s web site includes a directory of more than 80 member caves by state, including direct links to each cave’s web site. The site also includes information about basic cave science, and helpful tips to better enjoy tours.
The National Park Service protects numerous caves across the United States, including several open in the Rocky Mountains. The Park Service’s Cave and Karst Program web site includes listings of parks that feature caves, as well as a photographic gallery, links to other cave-related web sites and downloadable PDF issues of Inside Earth, a quarterly newsletter about Park system caves. These informative newsletters contain fascinating news and information, some of which has not otherwise been announced to the public.
Before heading off on your underground journey, another worthwhile web site is the American Cave Conservation Association. The ACCA is America’s leading conservation group, working to study, preserve and protect caves and karst features. The non-profit association’s site includes many useful pages and sections, including a section specifically for kids. Many puzzles, games, educational activities and even a quiz provide children with a fun opportunity to learn more about caves.
Once you’ve loaded your car, filled up with gas and are on your way, there are numerous opportunities to explore the underground West.
