Mammoth Cave —the longest tunnel cave system in the world—formed over 10 million years ago, but wasn’t designated as an official US national park until July 1, 1941. The cave earned its name for both the size of its massive caverns and its hundreds of miles of explorable passageways. Within the cave’s 412 miles of explored tunnels, visitors can choose from a variety of cave tours (from self-led to twinkling lanterns to wheelchair and kiddo accessible). Above ground, head to Mammoth for hiking, horseback riding, and camping within the park’s more than 52,000 acres of scenic Kentucky landscape. The Green and Nolin Rivers run through the park, giving guests ample opportunities for canoeing, kayaking, boating, and fishing.
Where is Mammoth Cave National Park?
Mammoth Cave National Park is tucked amongst the rolling hills of south-central Kentucky’s gorgeous green countryside, just 35 miles northeast of Bowling Green and 90 miles south of Louisville. The park is surrounded by kitschy roadside attractions and is only a short drive from Kentucky’s famed bourbon distilleries.
Mammoth Cave Facts
Thanks to its underground location, Mammoth Cave is only mildly affected by the changing seasons. Temperatures hover around 54°F year-round. Over the years, the Mammoth Cave has been used as a church, wedding venue, and tuberculosis hospital. Today, Mammoth Cave is the world’s longest known cave system, with much more still to be explored.
Mammoth Cave Weather
Because of its steady year-round temperature, a tour of Mammoth Cave serves as a cool retreat in the summer and a warm welcome in the winter. Of course, most of the activities on the 53,000 acres of land above the park are best enjoyed May through September when Kentucky’s temperatures are best suited for being outdoors. Mammoth Cave’s busiest months are June, July, and August.
