Bats and white nose syndrome
White nose syndrome is a fungal disease, well established in the eastern portion of North America and recently found in the west. It does not affect humans, but has proven lethal to bats. If you have been to a cave or mine in the past five years, do not wear the same clothing, shoes or accessories as you wore there on our caverns tour. If it cannot be avoided (for example, eye glasses or shoes) please contact park staff the day of your visit in order to obtain a disinfecting wipe. You can find decontamination protocols for anything that may have come into contact with the fungal disease at www.whitenosesyndrome.org.
The road to the Upper Visitor Plaza is closed to motor vehicle traffic October 1-April 30 every year. Visitors are still welcome to walk or bicycle along the road, but it is not maintained regularly during the winter months so may be impassible or partially blocked due to ice, snow, or rock debris.
From May 1 through September 30, the visitor center will be open 7 days a week from 9 a.m. - 4:30 p.m. The park gate will be open from 8:30 a.m. - 5:30 p.m. (6:30 p.m. from Memorial Day weekend to Labor Day).

What About Bats?
How Does FWP Monitor Bat Populations for White-nose Syndrome?
FWP has begun its annual surveillance for Pseudogymnoascus destructans, the fungus that causes white-nose syndrome in bats. This disease has caused devastating declines in bat populations across North America, and it was first detected in Montana in 2021. Since the detection, Montana FWP has begun to see declines in bat populations within the state. Tune in to witness the crucial steps being taken to safeguard our winged night mammals!
