If you haven't been to Mammoth Cave recently, there's one major website that thinks you need to put it on your to-do list pronto. It's been called out as a must-visit Idaho destination.

Only In Your State gave the kudos to Mammoth Cave thanks to its rich history and they were even impressed with the bird museum, too. We love birds, but that's another story.

If you've never ventured to Shoshone to go spelunking in Mammoth, there are many, many videos that will give you an idea what to expect. This flashlight tour is one of my favorites as it also shows some of the bomb shelter signs that only a doomsday prepper could love.

I agree with Only In Your State on this one. Mammoth Cave and some of the other ice caves to our north are must-see places. There's only a $10 adult admission to get you started on your underground journey.
