And while those are great, we'd love to get beyond them. In your honest opinion, what's the best national park in your state? Or the best national park you've ever been to? And why?

Although if you're familiar with Aron Ralston's story of sawing his right arm to free himself from a boulder — immortalized in 127 Hours — then you might have heard of Canyonlands.

That honor goes to Mammoth Cave National Park in Kentucky, which features more than 400 miles of mapped caves. 

It's also quite possible that the best national park in your state simply is the most popular one.
