The Ultimate List of Caves in America

There is no shortage of places to explore in America! Whether it be deep inside Texas or climbing around New York, there’s always something new to see and experience.

What kind of caves are we talking about?

Limestone caves

These are caves that formed by the dissolution of limestone. They are primarily found in the eastern quarter of the United States and southern Canada

Karst caves

These formed from soluble rocks such as gypsum, which dissolved into a base rock like sandstone during rainstorms or snowmelt. These types of caves can be very large with features like stalactites and stalagmites.

Rock caves

These are formed as a result of weathering and erosion, where the softer rock is worn away by wind or water to create roofless openings in the earth. These types of caves are often found in the Great Lakes region and the Southwestern United States.

Lava tubes

This type of cave forms when lava cools enough that it begins to harden. The ceiling may never form and the roof is often at a much lower level than the ground surface outside of the tube.

Crystal Caves

These are caves that form in a type of limestone called tufa, which is porous and has an irregular surface.

Salt Caves

These are formed when an ancient sea dries up. It results in a layer of salt over the ground and can create cavities by sucking water from the soil

Ice Caves

These form on glaciers, due to constant freezing and thawing cycles. The caves are generally not very large but ice sculptures often decorate their walls.

Bat Caves

These are caves that house populations of bats.

Wild Caves

These are caves that have not been explored and remain largely unknown.

Mining Caves

These caves are formed when a mineral deposit like gold, silver, or iron is found and mined.

And let’s not forget:


These are a type of cave with large spacious rooms. These types of caves often have formations like stalactites, stalagmites, or columns!
