Ohio is a wild card.
You never know what sort of hidden gem you’re going to uncover next. From the world’s largest accessible glacial grooves to the oldest concrete street in the country, Ohio is hiding some really unique places you simply won’t find anywhere else. Here are 14 awesome things you can do in Ohio—and nowhere else in the whole wide world.
1. Visit the Birthplace of Rock and Roll
Cleveland is the proud home of The Rock and Roll Hall of Fame. It belongs on every American's bucket list. You can find it at 1100 E 9th St., Cleveland, OH 44114.
2. Explore the largest accessible glacial grooves in the world.
Although you'll have to take a ferry to see this natural wonder, it's absolutely worth it. Few people are aware that Kelleys Island is home to the largest accessible glacial grooves in the world. The Glacial Grooves Memorial measures 400 feet long and 35 feet wide. You'll find them at 739 Division St., Kelleys Island, OH 43438.
3. Examine the world's largest celestite geode.

4. Stroll down "America’s Oldest Concrete Street."
The small city of Bellefontaine proudly claims "America’s Oldest Concrete Street," which dates all the way back to 1891. (Don’t worry; it’s not falling apart. It’s been maintained since the 19th-century.) Today, you can find the Court Avenue street sign by the courthouse, but you can no longer drive on the street itself. (As an added bonus, nearby is the "World's Shortest Street," McKinley Street, which is only 15 ft. long.)

8. Examine the Great Serpent Mound.
While Ohio is full of multiple earthworks from various cultures, there’s no earthwork in the world that compares to the Great Serpent Mound—both in shape and size.
