The refuge is closed to the public.

This refuge exists to protect endangered species habitat.

Pilot Knob National Wildlife Refuge was established in 1987. The 90 acre refuge, a donation from the Pilot Knob Ore Company, is located on top of Pilot Knob Mountain in Iron County, Missouri. Pilot Knob is a peak in the St. Francois Mountains above the Arcadia Valley.

The refuge contains abandoned iron mine shafts excavated in the mid-1800s that have since become critical habitat for the federally endangered Indiana bat. The Indiana bat hibernates within the abandoned mine shafts located at the peak of Pilot Knob Mountain. The bats generally arrive in September and leave in April.
