Located about 50 miles south east of Rochester, Niagara Cave is one of the Midwest's largest limestone caverns. The cave was carved out by underground streams, its ceiling stands over 100 ft in height, with deep canyons below. During the one hour guided tour visitors encounter fossils that have been dated to over 400 million years old, a 60-foot waterfall, massive stalactites, calcite flowstone, plus much more.
The cave's temperature is consistently 48 degrees (F) year around, so bring along a light jacket or sweatshirt. Walking shoes are also recommended.
Hours: Hours vary by season; regular season is May-September.
