Welcome to Hocking Hills State Park in Logan, a 2,356-acre wonderland that somehow remains Ohio’s best-kept natural secret despite being just an hour from Columbus. The crown jewel of Hocking Hills isn’t hiding – it’s right there on every brochure and website – yet somehow, the photographs never do it justice. While Old Man’s Cave and Ash Cave are technically recess caves (rocky overhangs), Rock House earns the distinction of being the only true cave in Hocking Hills State Park. For more information about trail conditions, seasonal events, and visitor guidelines, visit the official Hocking Hills State Park website or Facebook page before your trip.
