Niagara Cave is one of the most fascinating and unique geological attractions in the United States. During the one-hour guided tour, visitors will witness a waterfall, nearly 60 feet high, stalactites both delicate and massive, calcite flowstone, fossils that have been dated to over 400 million years old, and a wedding chapel in which over 400 weddings have been performed, plus much more.

Niagara cave is a constant 48 degrees year around, so a light jacket or sweatshirt is suggested. Walking shoes are recommended. Also, because there are several sets of stairs on the cave tour wheelchairs and strollers can not be used on the tour. However, the gift shop is wheelchair accessible.

Niagara Cave is not a bat habitat.



You may want to pack a picnic lunch and enjoy our 10 acre picnic grounds.  We offer a covered picnic shelter that seats over 100 people.  You may also hike our own short nature trail.



After your tour you may want to try your luck mining for real gemstones or genuine fossils. Just purchase a bag of mining rough from the gift shop and take it to the sluice outside.  Pour your rough into the screened trays provided and watch for gemstones or fossils appear before your eyes. Use the identification board to see what you?ve found, or ask at the counter and we?ll be happy to help with some of the trickier ones.
