Ultimate Guide to Cave of the Mounds, Wisconsin (Tours, Pricing, History, Map)

Cave of the Mounds, a naturally formed limestone cave near the Blue Mounds in Wisconsin, is named after the two hills in the vicinity known as the Blue Mounds. Located on the southern slope of the Eastern hill, the cave’s beauty lies in the many mineral formations called speleothems.


Cave of the Mounds is so beautiful that it has been often promoted as the ‘jewel box’ of American Caves. In 1987 the cave was designated as a National Natural Landmark. 

With nature as the classroom, it is no surprise that this modest-sized show cave sees everything from school field trips to Scout groups.

Cave of the Mounds, Wisconsin

The cave opened its doors in 1940, and since then, it has welcomed millions of tourists. The cave remains open throughout the year, and even during the busy summer months, the tourists need not wait long for the cave tours as the tours are brilliantly managed. 

History of Cave of the Mounds

History of Cave of the Mounds

The limestone from which the cave got carved was formed approximately 488 million years ago during the Ordovician Period. North America, during these times, was covered in warm and shallow seas. The cave began forming around a million and a half years ago, precisely like some of the other caves are formed. Rainwater seeped into stone through a large crack on the rock’s surface, known as the cave’s lifeline. It is a gradual process and continues even today. 

The Europeans settled the area around the Blue Mounds in 1828 by Brigham, a lead miner from Massachusetts. He came to Wisconsin to join the lead rush of 1820. He had set up operations to the North of where the cave lies today. He died after a long life but never knew that a beautiful cave had existed beneath the Brigham Farm.

On 4th August 1939, the Cave of Mounds was accidentally discovered when the workers of a limestone quarry blasted a section of the quarry and exposed an opening to the cave. As soon as the discovery was made, the work at the quarry was stopped, and it was never continued.

After this, the cave was closed to prevent damage from the souvenir seekers who would remove pieces of stalactites and stalagmites from the cave and take them home. The foot-sized holes in the flowstones left by the early explorers can still be seen today.

In May 1940, the cave was reopened with lights and wooden walkways fully installed. Over the years, the wooden walkways have been replaced by concrete ones as they accommodate more visitors. Theatrical lighting has also been installed to highlight the colors and shapes inside the cave fully. In 1987, the cave was designated as a National Natural Landmark.

That means they have not only a responsibility to protect but chose to help educate others on how to preserve the geological gem for future generations.

They hire local kids

This part cracks me up as we have not one, but two family members who actually worked here as teens.

This was the perfect job for teens at Mt Horeb High and still is today. If they were too young to actually lead tours or guide in the caves, they were on “bumper sticker duty”. It was common back then for tourist attractions to place bumper stickers on your car when you were visiting them.

Keep in mind that the bumper stickers weren’t what they are today. Back then, instead of the vinyl-type adhesive sticker we know now, they were cardboard rectangles that had holes in all four corners. There were metal brackets, or clips, that went in the hole and then were fastened around the metal bumper to hold it in place.

These were beyond easy to remove and actually expected. My husband’s Uncle Bob regaled us with all the fine details and Cousin Hazel could still recite the pre-cave tour spiel perfectly at 86.

During our tour, we asked one of the teens in the cave if he wanted to be a Geologist. “Oh heck no, but this is a great job right now” was the enthusiastic reply.
