Visitor Tips and News About Bat Hibernation Mines
Apparently over a million bats come to hibernate in the mine shafts of these old iron mines. They have a bat viewing area where you can sit and watch the bats pour out of the mine from just a few feet away. The show starts at dusk. However we sat around for about and hour on either side of sunset in late September and got to see 5 bats. I think the bats had already started their long winter's nap. If the weather has been warm I think you may have better luck. There is also a resident population that live in the mines during the summer. If you don't see the bats it's a great site to watch the sunset.[Phrank Phester, 10/02/2011]
