Niagara Cave

This cave is known as a geological marvel with 60-foot waterfall, a 100-foot ceiling with canyon-like walls, wavy flowstones, and fossils. Even though the cave has been here for millions of years it was only discovered in the first half of the 20th century. On your tour you'll walk a mile underneath the Earth's surface and see fossils of animals that once lived over 450 million years ago. For the lovebirds there is a subterranean chapel where hundreds of weddings have been performed. The tour costs around $16 for most people but parking is free.
