Tourist Attraction
Niagara Cave in Minnesota was discovered in 1924 when three local boys lowered themselves into a sinkhole to rescue some lost pigs and then explored the cave's depths.
It opened for public tours in 1934 and is one of only two publicly accessible caves in the state. The cave features stunning natural formations including stalactites, stalagmites, and a spectacular 60-foot underground waterfall that flows into an underground river, creating a mesmerizing sight and sound experience.
Visitors can explore well-lit pathways showcasing fossils, unique rock formations named for their shapes, and an underground chapel that has hosted more than 400 weddings. Niagara Cave is known for its accessibility, natural beauty, and rich scientific and cultural history, receiving about 25,000 to 30,000 visitors annually.
In 2015, it became the first commercial cave worldwide to be powered entirely by solar energy, underscoring its commitment to sustainability and preservation.
