Sept. 13 is the first International Day of Caves and Karst. This is a global opportunity to raise awareness about the vulnerable groundwater supplies that serve roughly 10% of the world's population.

Karst landscapes provide drinking water to more than a billion people, and they are especially vulnerable to pollution.

And here's the challenge: many people who live on karst or depend on it for their water have never even heard the word “karst.” Now is your chance to help change that.

Share information. Host an event. Talk about caves and karst. Help your community understand where its water comes from — and why protecting these vulnerable underground environments matters.

Learn how you can participate, get free downloadable resources, and register your event: https://www.caveskarstday.org

Unfortunately due to catastrophic local flooding, cave tours will be closed today. Our gift shop and museum are still open, as well as viewing access of the sinkhole and entrance.

❗️Please plan for alternate routing to Horse Cave. Most of 218 is flooded, as well as parts of 31w. ❗️
