FAQs about flying to Kentucky

What is good to know if travelling to Kentucky?

  • Kentucky is the home of bourbon, and many of the distilleries are open for visiting (and for some tasting as well…) Travel the “Bourbon Trail”, in the hills around Lexington, and you can see where 95 per cent of the world’s bourbon comes from. Famous names include Wild Turkey, Maker’s Mark and Buffalo Trace.
  • The appropriately named Mammoth Cave is the world’s longest cave system. You can visit the surrounding park area for free, but there is a charge for a tour of the caves. It’s well worth taking a guide (rather than completing a self-guided tour) – the cost is a dollar more and you’ll find out all sorts of fascinating information along the way.
  • Frankfort is the capital of the state and houses many attractions, such as the Kentucky State Capitol and the Zeigler House. Also worth a visit is Daniel Boone’s grave, in the city’s cemetery. As well as seeing the grave itself, the view from the spot – overlooking the river and the Capitol – is stunning.
  • Thomas Edison lived in Louisville on Washington Street. His house is now the site of a museum in his honor.
  • Sanders’ Café in Corbin is the birthplace of Kentucky Fried Chicken. Colonel Sanders operated a gas station here in the 1930s and served his fried chicken to passing travellers, from his own kitchen table. Today, the restaurant is still operating, and an attached museum tells you all you could ever want to know about the food.
  • If you’re interested in the state’s thoroughbred horses, visit the Kentucky Horse Park Home or the Thoroughbred Centere, both in Lexington in the middle of the Bluegrass area.
