Cave of the Mounds

Discover the beautiful minerals glistening inside this massive cave.

Varying from 40 feet to 60 feet underground, the Cave of Mounds is located in Blue Mounds, Wisconsin, on the old Brigham Farm. Ebenezer Brigham founded the farm in 1928 and never knew the cave existed since it was in a closed system with no natural entrances. Ebenezer hand down the farm to his great-nephew, Charles Brigham, who used it mainly as a dairy farm and would occasionally lease out quarry rights to varying contractors.

In 1939 while extracting limestones, some workers came across the cave completely by accident. They blew a 25-foot hole into their dig site, revealing a permanent entry. It didn't take long for the incident to spread and for curious folks to see the newly found cave. The traffic became so intense that they temporarily shut the cave down and established a proper touring system. 

In 1988, the Cave of the Mounds got the National Natural Landmark title and had been in partnership with the National Park Services ever since, securing the cave’s safety for years to come. Be prepared to find rare minerals and crystal formations as you travel the illuminated path, led by an informative guide. The Cave of the Mounds is sure to take your breath away. It is open daily from 9 am to 5 pm no matter the weather, except on Thanksgiving, Christmas Eve, and Christmas Day.
