What Hotels are closest to the Facility?

Facility? It's a cave.

I'm not a fan of camping. As for hotels, that was a "driving day" for us so we spent the night several hours away.

Why stay @ a hotel when you can camp in the cavern 😉😉😉

We stayed at the Americas Best Value Inn. It's close, simple, and inexpensive. You get what you pay for.

Best Western Tree City Inn is about 15 minutes away. There are several AirBnB’s, and cabins at Rock Island and Fall Creek Falls State Parks, and wonderful accommodations at The Retreat at Center Hill Lake.
