The caves are filled with snow during the long Idaho winter and slowly melt out in the spring. In a typical year the cave entrances are not free of snow and ice until mid-May. Check current conditions...
Before entering any cave you must be "screened" for white-nose syndrome. If you have boots or other gear (pants, tops, hats, gloves, pads, packs, or anything soft/porous) used in caves or mines outside of Craters of the Moon, please leave these items at home. This is an effort to prevent the spread of white-nose syndrome, a deadly fungal bat disease.
Please do not bring food into the caves or leave trash in the caves. There is a trash can located in the parking lot. Remember that all cave features are fragile and irreplaceable. Do not remove any rocks or other objects from the caves area.
Exploring the Caves
There are five caves you can explore within the Monument. Four of these caves can be found along our Caves Trail, the other is located on the Broken Top Loop Trail. All other caves found in the monument are not open to visitation in order to help protect our bat populations.
