Is there any place to kayak there or nearby? Can you swim under the waterfalls?

Where is the closest cabin rental to hike and kayak. Also, we heard there was zip lining. Anyone heard the same? Do the cabins have fire places?

You cannot swim or walk under the waterfalls or in any natural water are (creeks, ponds) at Hocking Hills State Park. It not only hurts the wildlife living there but rocks, logs, sticks fall from the cliffs above. You can kayak at Rose Lake (adjacent to the campground), Lake Logan, or the Hocking River.

Kayak lake Logan all the time. No to the swimming under the falls. There are signs posted.

Lake Logan around 12 miles from Old Mans Cave SP.
