The last part of the Oregon Caves National Monument tour is up a long corridor called the exit tunnel. This is a man made tunnel that is fairly long and doesn’t have much in cave formations to look at:
This doesn’t mean that this part of the cave lacks interest. This is where you may get a chance to see the small bat population which hibernates in Oregon Caves over the winter. Although most bats at Oregon Caves roost under the bark of old-growth trees in the summer, some bats enter the cave during very cold periods. This is probably because their usual roosts under the bark on dead old-growth trees don’t provide enough insulation. There are also a few individual bats which hibernate in Oregon Caves during the winter. I was able to see one of these hibernating bats (although I did not get a photo since I didn’t want to disturb him). The most commonly seen bats at Oregon Caves are Townsend big-eared bats (especially in winter), Yuma bats, and long-eared myotis bats.
Once you exit the cave, you find yourself in a moss covered wonderland above where you entered the cave:
It is then a 0.3 mile hike along a paved path back to the visitors center.
