I write like it's my job - because it is! I have a Master's in English and love words: crossword puzzles, Scrabble games, Wordle, and, of course, good, old-fashioned books.
I'm a writer and editor at OnlyInYourState, and a contributing writer at Cincinnati Magazine. I love the Great Outdoors and am endlessly awestruck by this beautiful country of ours. Coffee keeps me going, yoga keeps me sane, my kids keep me grounded, and my writing keeps me inspired.
In the everyday hustle and bustle of life, it’s easy to lose sight of what’s in front of us. Or, rather, what’s below us. We’re talking, of course, about Mammoth Cave, the world’s longest underground cavern, Kentucky’s iconic national park, and a true natural treasure. Most of us live within an easy day trip of this world-famous wonder, but how many of us forget that it’s there? Allow us to remind you, and urge you to embark on a marvelous and unforgettable adventure in the longest underground cavern in Kentucky, the U.S., and the world!
A natural wonder million of the years in the making, Mammoth Cave has a history as deep and fascinating as its tunnels and formations.
By far the longest cave system in the world, this sandstone labyrinth encompasses more than 400 miles of known passageways, with more being discovered each year.
For intrepid history buffs, the Violet City Lantern Tour is a must. A truly historic way to experience Mammoth Cave, this tour travels exclusively by lantern light. At three hours long, this tour winds through the history and prehistory of Mammoth Cave as you wander through huge, broad tunnels.
The Domes & Dripstones Tour is a fan-favorite, visiting areas of Mammoth Cave that have been used for nearly 100 years. This tour begins in a sinkhole, passes through huge domes, amazing formations, and ends in the dripstone section known as Frozen Niagara, for an underground adventure that's unparalleled.
At nearly four hours long, this lengthy tour explores the great geologic diversity of Mammoth Cave. Going through slot canyons, tubular passageways, tall canyons, and tunnels sparkled with gypsum, this tour is the longest walking tour in the national park, and a deep dive into the longest underground cavern in the world.
While many of Mammoth Cave's feature numerous steps, the Accessibility Tour is the best choice for visitors with mobility devices, motorized wheelchairs, and walkers. Unique rock formations and historic writings from the 1800s line the paved sidewalk through the picturesque Snowball Room and Cleaveland Avenue, making this an epic underground adventure for all.
There's nowhere in the world like Mammoth Cave. And with a robust menu of epic, guide-led tours, this extraordinary underworld is a place everyone can explore, experience, and enjoy.
