Discovered in the 1920's; the naturally decorated Frozen Niagara section remains one of the most famous at Mammoth Cave, and serves as a highlight featured on two tours this winter. The Domes and Dripstones tour is moderately strenuous and requires a two hour hike and numerous hills and stairs to reach this point.
The Frozen Niagara tour is a short tour which offers a chance to visit this area with only 12 stairs. This tour is ideal for anyone with difficulty walking long distances or negotiating stairs. This tour includes a 10 minute bus ride to and from the entrance.
Our winter tour schedule has the Frozen Niagara tour daily at 12:30 and Domes and Dripstone tour daily at 1:00 PM.
