The "Hi di Hi Woods" is a kids trail on Snowmass. The Elkhorn Tunnel used to be a part of it, but is not there anymore. After the Elkhorn Tunnel disappeared, the Bat Cave was added.

Even though the Elkhorn Tunnel is not a part of the Hi di Hi Woods anymore, the sign has survived and is now (as of February 2018) mounted on the front of a building next door to the Lizard Lodge. See two photos below (click on images to enlarge).
