Speleofest is an annual caving event in Kentucky that takes place on Memorial Day Weekend. It was started in 1972 by the Louisville Grotto and has continued ever since. Proceeds from the event have allowed the Louisville Grotto to purchase the Lone Star Preserve in Bonnieville Kentucky, which functions as a permanent location for Speleofest and a year-round educational facility for caves and karst. The Lone Star Preserve has grown to 126 acres in recent years and has 6 caves on the property, 3 of which have over 500 feet of passage.
What to expect
Once you pay for entry to the preserve, there is no additional cost for any activities. The only cash you need is for food and gear vendors if you wish to make purchases. The event kicks off on Friday night with a bon-fire party in the evening to get acquainted; drinks and snacks supplied by the grotto. Saturday evening there is banquet dinner, guest speaker, and a door prize give away. On Sunday afternoon there is a Wine and Cheese party inside Saltpeter Cave, which is typically followed by music and dancing at the shelter house. There are other unscheduled games and activities on site as well.
The Green River and Nolin River nearby have several classic sections of class-1 boating for a satisfying day trip. Nolin lake is nice as well. Some years there are led kayaking trips if there is interest; follow the Speleofest Facebook page for updates. There are printed maps and directions available on site for most of the popular kayaking routes if you wish to plan a self-led trip.
