Mammoth Cave is the superlative superstar of the Bluegrass, earning the state world-wide acclaim and attention. A bucket-list must, the cavern system features over 400 miles of underground caverns and passageways, with more miles being added all the time. In addition to its epic underground tours, aboveground adventures abound at Mammoth Cave, too. The trails are spectacular, and the national park is, pardon the pun, a stellar place for stargazing. Oh, and did we mention it’s extraordinarily beautiful? It is, and it’s not just us who think so. Travel + Leisure recently named Mammoth Cave the most beautiful place in Kentucky… and we couldn’t agree more.
