An opening of an ice cave made from molten rock was mentioned in 1898 when a settler family used it to store milk and butter. The entire cave was formed by lava some 500,000 years ago. 

Today, Niter Ice Cave is mostly a roadside attraction. It’s located about a hundred yards from the main road, and a painted sign announces its location. You can usually find a few icicles forming where water drips down from the top of the cave.

Know Before You Go

The steps tend to be wet or icy, use caution when entering the cave.
