The same incredible geologic processes that formed Idaho’s awe-inspiring mountains and carved our breathtaking rivers also formed yet another Idaho wonder: caves of every size, shape, and color — some impossibly located, others utilized by Native Americans as shelters long ago.

There are 3 basic types of caves in the Gem State: corrosion, solution, and lava, all of which make phenomenal exploring grounds for the daring and non-claustrophobic. Some of these caves may take some extra hiking to get to, but if adventuring in underground tunnels or historic hideaways is your thing, Idaho is definitely the place to be. So grab a flashlight, don a jacket (it’ll be chilly in there!), and check out these 8 Idaho caverns:

It’s safe to say that Idaho’s underground network is an adventurer’s paradise, but there are dozens more caverns that we haven’t listed and/or need photos of. If you’ve ever explored an underground paradise or lava tube in Idaho, please share your stories and pictures below!
