Kentucky Down Under provides outback-interested wayfarers with an arsenal of authentic Australian animals and culture, and a tour through a Kentucky cave. Staff members can help guests tailor a unique adventure with stops at a walk-in aviary to gawk at Australian finches, as well as a guided tour through the kangaroo-, wallaby-, and emu-laden Outback. At Camp Corroboree, visitors can discover pieces of Aboriginal culture, including the soothing hum of the didgeridoo and the delicate balance of physics and magic in a boomerang. In addition to Aussieness, Kentucky Down Under showcases a local treasure with the Kentucky Caverns. During the 45-minute tour of the earth hole, explorers can witness the ever-changing formations of stalactites, stalagmites, and life-size Dennis Franz rock statues.

Between animal petting and stalactite hugging, KDU-goers can grab a salad, sandwich, or bison burger at the Outback Café.

The caves are open year-round, but animal areas are closed at certain times of year.
