Questions people ask
How many caves can you tour in Idaho?
3 show caves run public tours. We leave out wild caves that are closed, gated or need a permit.
What should you wear in a cave?
Closed shoes with grip, because paths are often wet. Most caves stay between the high 40s and low 70s °F all year, so a light layer is enough.
