Hocking Hills transforms in winter. Waterfalls freeze into dramatic ice formations in January and February after sustained below-freezing temperatures. The trails are quieter, the gorges more dramatic, and cabin hot tubs hit different when it's 25°F outside. The legendary Winter Hike — third Saturday of January — draws 5,000+ hikers for a free, 6-mile trek from Old Man's Cave to Ash Cave.
Winter stays offer the best value of the year. A cabin that runs $300/night on an October weekend might be $150 midweek in January — with arguably a more dramatic landscape.
