A popular hike through the gorge leading to waterfalls and a sandstone cave.
Take the Rim Trail in Hocking Hills State Park, which descends into the deep gorge and takes you alongside a stream as you head towards a number of cascades and interesting rock faces.
Rim Trail can be linked to Cedar Falls, as well, or from the Upper Falls you can take Grandma Gatewood Trail for a 6 miles trail through the park. This is the site of the annual Hocking Winter Hike in January, which can see as many as 5,500 people on the trail.
Keep en eye out for the detour to Lower Falls as well, it's worth it.
Camping and lodging are also available nearby.
