This one-of-a-kind inn is built inside a man-made cave on a cliff. It's not easy to get to -- the entrance is reached by walking down a sloping path and intermittent steps cut into sandstone. There is a short ladder at the bottom of the path with three wooden steps that lead you to the flagstone porch.

There is a hot tub under the oak trees and a self-guided nature trail through 160 acres of Texas ranchland.
