Let’s kick off our ranking with Olympic National Park, located in the state of Washington. The park was designated as a National Park in 1938 during Franklin Roosevelt's presidency.

What makes this National Park so remarkable? Well, it has three distinct ecosystems : the temperate rainforest (which is the only one in the contiguous United States), the rugged coastline, and glaciated peaks. This variety of landscapes brings a rich biodiversity to the area that is definitely worth visiting!

Joshua Tree National Park

We know it’s in the name, but did you know Joshua Trees aren’t actually trees ? They belong to a subgroup within the yucca species. These plants can live for over 150 years, and you can find them in this park, among other places.

Similar to Olympic National Park, this park features three separate ecosystems: a part is within the Colorado Desert, it also includes California juniper, the San Bernardino Mountains, and the Mojave Desert where you’ll find the famous Joshua trees.

If that wasn’t enough reason to pay a visit, you have to know that this park has one of the darkest skies in Southern California, providing an excellent opportunity to spot the Milky Way galaxy!

3

Grand Teton National Park

Located in Wyoming, this National Park is home to what is believed to be the youngest mountain range in the Rocky Mountains: they are only between six and nine million years old!

In Grand Teton, you’ll find incredibly tall mountain peaks (the highest reaching 13,770 feet) and a wide variety of wildlife, including grizzly bears, gray wolves, coyotes, moose, and more.

Established in 1929, the park was later combined with the Jackson Hole National Monument, in 1943. Today, the town of Jackson Hole, located to the south of Grand Teton is the main hub of activity in the area. And, if you visit, you can actually make it a two-for-one trip because it's only 10 miles away from Yellowstone National Park, which will be featured later in this list!

4

Acadia National Park

Acadia National Park receives over 3.5 million visitors each year, and that has secured a position in this ranking. The park features granite mountains, rocky coastlines, ponds, lakes, and all kinds of plants and wildlife. It is an Atlantic shoreline beauty!

The park was first named Sieur de Monts National Monument by President Wilson in 1916. In 1919, it was renamed Lafayette National Park, but that wasn’t the end of it. In 1929, the name officially changed to Acadia National Park, honoring "Arcadia," a region in Greece that is pretty similar to the park!

5

Yosemite National Park

Although it is not one of the top three most visited national parks in our country, the park’s popularity is undeniable because it was the one park that paved the way for the National Park System as we know it today. The establishment of this area as a national park is largely credited to John Muir, a Scottish naturalist who recorded the beauty of the area and raised awareness around it.

Today, Yosemite covers an area of 759,600 acres and is home to granite cliffs, giant sequoias, mountains, glaciers, streams, and waterfalls. It is predominantly classified as wilderness and is, of course, a protected area.

Rocky Mountain National Park

This national park is a gem in Colorado and the 4.5 million visitors it receives each year is a testament to that. The park boasts rugged mountain terrain, alpine lakes, and dense forests—making it simply breathtaking.

It was established in 1915, and it is home to Longs Peak , which stands at an impressive 14,259 feet, and the famous Trail Ridge Road, the highest paved road in the country! Besides, this park is home to over a thousand types of wildflowers and 280 species of birds, just to mention a few details that make it an incredible place in America!

7

Yellowstone National Park

Yellowstone National Park is a true icon of the American West, and with over 4 million visitors each year, it’s easy to see why. The park lies across Wyoming, Montana, and Idaho, and it showcases wilderness at its best: geysers, hot springs, rivers, and canyons co-exist within the area. It is also home to the famous Old Faithful , the visitor’s favorite: an ever-erupting geyser!

Yellowstone holds the honor of being the very first national park in the world, having been established in 1872. The idea of preserving this vast and unique landscape for future generations was revolutionary at the time, and it laid the groundwork for the global national park movement. Have you had the chance to visit it yet?

8

Zion National Park

Image: Jamie Hagan

This deserted wonderland is located in Utah and it is known for the towering red sandstone cliffs and deep canyons as well as the glowy rock formations .

Established in 1919, it was Utah’s first National Park, and it is home to over 100 miles of trails. Car access to the park is limited, so there are plenty of hiking trails within the area. Moreover, this park is home to the second largest freestanding arch in the world which is 287 feet in length.

If you visit the park, you will surely make a stop at the Zion Lodge. But, did you know this is not the original construction? The original structure was struck by a fire in 1960, so the one you see today is actually a second version of it!

9

Grand Canyon National Park

Image: Michael Kirsh

You probably thought this was the most visited park in our country, but there’s another that holds that title! As for the Grand Canyon, it still is incredibly popular, and receives over 6 million visitors every year!

Located in Arizona, the Grand Canyon stretches 277 miles long and a mile deep. It was established in 1919 and it is only second in the ranking due to the powerful and awe-inspiring sights. That’s why it is one of the Seven Natural Wonders of the World .

Across the canyon, visitors can enjoy the Colorado River, where water carves layers of rock that have been in the area for millions of years. No words can capture its beauty, you just have to visit it to understand it.

10

Great Smoky Mountains

To close our ranking, we present the most visited National Park in America: the Great Smoky Mountains. Did you guess it right? Even if you did, you would have never guessed the number of visitors right: a shocking 13 million visitors a year ! Now, the reasons? Almost as many as its visitors.

The National Park was established in 1934, but the mountains that are housed in it were formed millions of years ago. It spans the borders between North Carolina and Tennessee and it is best known for its mist-covered mountains, lush forests, and the remarkable biodiversity of plants and animals.

With 800 miles of hiking trails, among which you’ll find the Appalachian Trail, preserved historic buildings, and peaceful retreats, it’s no surprise that the number one park on our list is also a favorite among visitors. Do you agree?

1

The horse diaper

Image: Lucia Macedo

Designed to catch manure in crowded cities—a problem once so severe that it shaped public infrastructure as well as the entrances to houses—the horse diaper was an invention meant to be strapped beneath working horses pulling carts and carriages.

The idea was to reduce disease and street filth during the horse-powered urban era. While the device saw limited use before automobiles rapidly replaced horses, similar designs are still occasionally used in modern veterinary practice.

2

The baby cage

Image: Taylor Flowe

Built as wire cages attached to apartment windows, so-called "baby cages" allowed infants to get fresh air when outdoor space was unavailable. Some models were guaranteed to safely hold over 30 pounds.

While alarming today and ultimately abandoned due to obvious safety concerns, the designs likely inspired some of the baby-proofing nets used today.

3

The pneumatic subway

Image: Eddi Aguirre

In the late 1860s, American entrepreneur and inventor Alfred Ely Beach set out to prove the feasibility of a human-sized pneumatic subway system beneath New York City, capable of moving both people and cargo using nothing more than air pressure.

The prototype was set up as a public attraction and carried passengers along a tunnel just over 300 feet long, from a station to a dead end. Despite its initial success, bureaucratic obstacles and high costs halted expansion, leaving it as a functional but largely forgotten underground experiment.

4

The mechanical horse

Image: Gabriel Tovar

Created for exercise and riding practice, the mechanical horse used a system of gears, cranks, and pedals to simulate walking and trotting motions while the rider sat in a saddle-like seat. It was marketed to urban riders and cavalry trainees who lacked access to stables or live horses.

Though bulky and impractical for widespread use, the device anticipated modern fitness machines by replicating real-world movements for conditioning and skill retention, rather than simple repetitive exercise.

5

The first metal detector

Image: Fer Troulik

After a failed assassination attempt on President James Garfield, Alexander Graham Bell hastily built an early metal detector in an effort to locate the bullet lodged in his body. The device functioned as intended, but it was unable to find the bullet because metal bed springs interfered with the signal.

Despite this setback, Bell’s early design proved the concept and directly influenced the development of modern metal detectors.

6

The pet-powered butter churn

Image: Matt Bero

In an inventive twist on animal-powered machinery, some 19th-century American farmers rigged small treadwheels for dogs, cats, or even goats to generate kinetic energy for churning butter. The animal ran inside the wheel, turning a rope or pulley connected to the churn.

While technically functional, the system was limited by the animal's willingness to cooperate and the small amount of power it generated.

7

The umbrella hat

Image: Claudio Schwarz

Robert W. Patten, often called the "Umbrella Man," patented one of the first commercially successful hands-free umbrella hats. It strapped a small umbrella directly to the wearer’s head, providing both sun and rain protection while keeping the hands free for work or walking.

His original design even included a mosquito net attached to the canopy. Patten didn’t enjoy much commercial success but became somewhat of an eccentric and comical popular figure, partly due to a series of comics that were inspired by his unusual invention.

8

The one-wheel motorcycle

Image: CJ Toscano

In 1971, American inventor Kerry McLean built and refined a monowheel—a one‑wheeled motorized vehicle in which the rider and engine sit inside the wheel’s circumference.

Since then, various attempts have been made to build on his original design, but it remains a niche vehicle used primarily for entertainment rather than practicality, as riders must be highly skilled simply to turn or even stay upright.

9

The first talking doll

Image: Holly Ward

In 1890, Thomas Edison embedded miniature versions of one of his most popular inventions —the phonograph—inside dolls so they could recite nursery rhymes.

While the idea was innovative, the technology was not yet there. The recordings were fragile, distorted, and often failed to work properly. The dolls were pulled from the market within weeks due to customer complaints, making it one of Edison’s rare commercial failures.

10

The glass harmonica

Image: Francesco Bovolin

Faithful to his eccentricity and inventive spirit, Benjamin Franklin redesigned the existing glass harp into a rotating spindle of glass bowls, played by touching the spinning rims with wet fingers, which he called the "glass harmonica."

The instrument produced eerie, sustained tones unlike anything else of its era. However, its fragile nature made it somewhat impractical, and the rotating mechanism posed a potential danger to the player if anything went wrong.

Alabama - Driving Regulations

Image: Ed 259

We have all tried to ride a bike with no hands when we were kids. You probably got to the point of taking the challenge one step further and driving with no hands on an empty road. Now, driving blindfolded is a bit extreme, right?

Alabama has a law that forbids drivers from driving blindfolded and that is not all, drivers aren’t allowed to drive if they can’t see what’s to the sides or in front of them. Now, if the law exists, that must mean it was needed at some point, right?

2

Louisiana - Pizza Party

Image: Kelvin T

Sending gifts is a great way to say "I love you" or "I’m sorry." Whatever the situation, we’ve seen it a million times: a knock on the door, a pizza delivery guy handing a pizza box, and a cheesy, but loving message as a topping: "I love you."

Well, if those were your plans but you live in Louisiana, you might as well think twice before you do it. This state has a law that forbids inhabitants from sending unsolicited pizza, no matter how considerate this gesture might be. If you do, be ready to pay a $500 fine. How much is your love worth?

3

Virginia - Halloween Arrangement

Image: Szabó János

All across America, when October comes, millions of people get their costumes ready for the spookiest night of the year. And we are not talking only children here. How many Adults-only Halloween parties have you been to?

However, the Halloween fun is limited in Chesapeake City, Virginia. Dress up all you want and party all night long, but don’t you dare go trick-or-treating alone if you are over 14 . Not because you might get haunted by ghosts, but because the law forbids you. And for the under-14s you know, let them know they have to be home by 8 pm according to the curfew. Quite a bummer, huh?

4

South Caroline - Pinball Limitations

Image: Senad Palic

Ah, to be young and play games again, right? The possibilities were endless, board games, card games, pinball… Well, not anymore, not for everyone, at least!

In South Carolina, pinball is forbidden for people over 18 years of age. And it has nothing to do with maturity, it is not that they don’t allow the fun in adults. The reason behind this regulation has to do with the fact that the game is considered addictive and dangerous for some reason we can’t figure out! Can you imagine what it is? If this sounds bizarre, wait until you read the next one!

5

Vermont - Permission to Get Teeth Done

Image: engin akyurt

Now, this is where America gets a bit bizarre. For a very long time, women have needed men’s permission to get all sorts of things done around the house and about their health. But as we said, society has changed and America has adapted to those improvements.

Surprising as it may be, Vermont has a law that requires women to ask for their husband’s permission before they get false teeth. You heard that right!

It must have been a surprise for the government itself as it is a law that is not enforced anymore, but it still hasn’t been overturned!

6

Kentucky - Marriage restrictions

Image: Samantha Gades

Speaking of husbands and wives, Kentucky must have seen the weirdest things when it came to marriages. That is fair, relationships are a complex business.

You fall in love and you get married. You fall out of love and you get a divorce. But love, funny thing, huh? You might fall back in love and want to get married again to the same person. Well, that is about it in Kentucky.

The state’s legislators have limited marriage so that no man can marry the same woman more than three times . This is just bizarre, even if you were allowed to do so, why would you? Right?

7

Oregon - Cemeteries Are Off the Limits

Image: Sandy Millar

Hunting is a very much praised activity in the United States. However, for different reasons, such as animal protection or nature conservation, some aspects of the hobby have been banned across the country.

In the state of Oregon, for example, you cannot hunt within the limits of a cemetery. Now, this sounds just about right, doesn’t it? After all, it is sacred soil. Well, as morally obvious as this may sound, the case of a specific hunter carrying his business in a cemetery led legislators to forbid the activity. Wait for it, this is nothing compared to the last prohibition!

8

Ohio - Mind Your Gas

Image: Juan Fernandez

Driving can be quite soothing, although it requires a high level of attention. You must check your tires, turn the lights on, and place the mirrors in the right position. And of course, you have to get the tank full before anything else.

Even if it seems quite unlikely that anyone would run out of gas intentionally, Youngstown, Ohio has a law that forbids drivers from running out of gas. If this happens, it is considered a misdemeanor offense. Running out of gas in the middle of your driving is bad enough, add a ticket to it!

9

Indiana - Horses Are Just Horses

Image: Holly Mandarich

Even if these majestic animals were used for transportation for a very long time , we can all agree that they have served their purpose and now is time to let them be. Well, Indiana must have been a place where this wasn’t the case until a law forbidding horse racing was passed.

The law actually says that horse-based travels are not allowed to run over 100mph . Even if the reasons are not so clear, one can only assume this was a nuisance for the inhabitants of the state.

10

Arizona - Donkeys Belong Elsewhere

Image: Erwan Hesry

This article comes to an end with what is, probably, the weirdest law of them all and it involves bathtubs and donkeys . Just saying it sounds bizarre.

Back in the 1920s, a very much-pampered donkey sleeping in a bathtub caused a home to flood. Don’t worry! The animal made it, although it didn’t quite notice as it was asleep the whole time.

Now, as a consequence, Arizona still has a law that forbids donkeys from sleeping in a bathtub in an attempt to avoid such an occurrence repeating itself! You better go buy a proper bed for your donkey now!
