A Mammoth Cave

Did you know Mammoth Cave is the largest cave in the world?

It has 400 miles of underground passages.

The 2nd longest cave is in Mexico and has 308 miles underground,

so Mammoth Cave really is a mammoth.

This is the historic entrance to the cave.

You can hike to it if you are interested.  

There is a gate preventing you from entering without a guide and getting lost.

We opted for the "New Entrance Tour" and accessed the cave from this metal door.

Mammoth is a large dry cave formed by an underground river rather than by seepage,

 so it doesn't have lots of formations like Cub Run Cave had.

This is one of the few formations, known as the Frozen Niagra.

 There is also a new visitor's center with lots of info about caves.

 And there are many hiking trails.

These steps are on one of the more popular trails, descending down into Cedar Sink.

On the Cedar Sink Trail, you can see where an underground stream 

comes to the surface and then returns below ground.

You never know what you'll see out in the woods.

 

The Turnhole Bend Trail offers views of the Green River.

 There are also several ferries crossing the local rivers.

I'm not sure why they have ferries instead of bridges, 

but they are kinda fun.

 And of course, there is a camping.

We shared our campsite with this big bug!
