What's The One Thing You Can Only Do in Ohio?

The World's Only Rock & Roll Hall of Fame

One of the most iconic things you can do in Ohio is visit the Rock & Roll Hall of Fame in Cleveland. This world-renowned museum is dedicated to the history and cultural impact of rock music, housing the most extensive collection of artifacts, instruments, and personal items from the genre's most influential artists.

World-Record Roadside Wonders

Ohio is a capital for "larger-than-life" attractions and specialized museums you won't find anywhere else:

• The World's Largest Cuckoo Clock: Located in Sugarcreek, known as "Ohio's Little Switzerland," this 23-foot-tall clock was once featured on the cover of the Guinness Book of World Records. It plays polka music every half-hour as a mechanical bird and dancing couple emerge.
• The Troll Hole Museum: In Alliance, you can explore the world's most extensive collection of troll dolls—over 20,000 items in a themed "troll cave."
• The Basket Building: In Newark, you can marvel at a seven-story office building designed to look exactly like a giant picnic basket—a permanent monument to Ohio's industrial creativity.
• The American Sign Museum: Cincinnati houses the nation's largest museum dedicated to the art and history of sign-making, featuring a century of neon, electric, and hand-carved wooden signs.

Aviation and Engineering Firsts

Ohio's unique heritage as the "Birthplace of Aviation" offers experiences found nowhere else:

• Huffman Prairie Flying Field: While the first flight happened in North Carolina, the Wright Brothers perfected the art of flight at this field in Dayton. You can stand on the actual ground where the airplane was truly mastered.
• The National Museum of the U.S. Air Force: Also in Dayton, this is the world's largest military aviation museum. It holds over 360 aircraft, including the original Wright Brothers' Flyer and various historic presidential planes.

Ancient and Natural Marvels

• The Great Serpent Mound: Located in Adams County, this is the largest earthwork effigy in the world, measuring 1,330 feet long and shaped like a snake.
• Crystal Cave: On Put-in-Bay, you can walk inside the world's largest known geode—a cavern-sized crystal formation discovered in 1887.
• The Glacial Grooves: Kelleys Island features the most prominent and most easily accessible glacial grooves in the world, scoured into solid limestone bedrock by ancient ice sheets 18,000 years ago.
