Kentucky is home to the longest mapped cave system in the World (a place you should visit). But along with this wonder, we have a very karst landscape with many caves that often do not get the attention they rightly deserve.
The Great Saltpetre Cave Preserve Open House is a "must" for anyone who is interested in the history of caves in Kentucky and how they have influenced our ways of life. My family visited this open house last year and I would highly recommend taking the time to visit what is normally a private cave. And the best part: it's FREE!
The schedule this year is as follows:
2016 Open House - Free Cave Tours Saturday, May 14, 2016 - 10am to 4pm Sunday, May 15, 2016 - 10am to 4pm
