The Ohio Department of Natural Resources will host its 44th Annual Winter Hike at 9 p.m. Saturday, Jan. 17. The guided trek (with refreshments!) follows the six-mile path from Old Man's Cave to Ash Cave, two of Hocking Hills State Park's most amazing resources. [Hike details]

Most know of the region -- but don't know much about it. To be honest, I wasn't that familiar with the most popular attractions before this weekend, when I organized a sightseeing tour with some friends. We hit Old Man's Cave, Conkle's Hollow and Rock House.

Check out the photos below for a glimpse into the beautiful region and its peculiar geology. Look for a full preview of the annual hike in Thursday's Alive.
