Harmony is located within the Driftless Area of the Upper Midwest.
The region was not covered by glaciers during the most recent ice age over 12,000 years ago. As a result, the landscape in our region is unique from the rest of the state. The countryside is rich with bluffs, rolling hills, springs, creeks, sinkholes and caves. Just south of Harmony, Niagara Cave is one of the most fascinating and distinctive geological attractions in the United States. The cave has been rated a premiere cave by the Fox News, Top Ten Things, American Towns Media, USA Today and Articlesbase.
Visitors to Niagara Cave will be taken on a one-hour guided tour, where they will hike a mile underground, discover fossils around 450 million years old, see cave formations both delicate and massive and view an underground stream as it flows over a waterfall.
Niagara Cave is 48 degrees year round, so wear a jacket and don’t forget to pack your sneakers!
One of Top Ten Rated Caves in the U.S. featuring a 60 foot waterfall, stalactites and stalagmites, ancient fossils, crystal wedding chapel, one hour guided tours, picnic grounds, gemstone mining, a gift shop, and much more.
