Anything but metric…🍌 B-A-N-A-N-A-S! According to the park, Mammoth Cave is approximately 3.37 million bananas long (banana for scale) which equals to about 426 miles (686 km) of surveyed passageway. Wow! That’s a bunch! While we know that Mammoth Cave is the world's longest known cave system, we haven't discovered all of it yet! Park partners like the Cave Research Foundation (CRF) are continuously mapping and surveying the cave to help us better understand the resource. Looking for something not so underground? While cave tours are the park's big attraction, there is plenty more to do and explore while visiting this beautiful wilderness area, such as hiking, camping, horseback riding, fishing and kayaking.
