Seattle Underground City

Did you know the remnants of Seattle's original streets are still accessible? Beneath the bustling streets of modern-day Seattle lies the Underground City , a network of subterranean passageways that formed the ground level in the 1800s.

By the end of the 19th century, after the Great Seattle Fire, it was decided to rebuild the city at a higher elevation to combat frequent flooding . So, these original streets, sidewalks, and storefronts were buried, and with it, much of their history.

Guided tours take people through tunnels and ladders and retell real and eerie stories about the history of the Underground City.

Have you ever heard of the underground Stalacpipe Organ ? Not only is it a one-of-a-kind interaction between keyboards and cavern stalactites, but it is also the largest musical instrument in the world, according to Guinness World Records.

This instrument lives in the Luray Caverns, Virginia. It consists of an electric console that taps on these ancient stalactites of varying sizes to produce musical tones. A subterranean wonder, these caverns are also known for their extraordinary size , housing towering stalactites and stalagmites, mirrored pools, and delicate drapery-like calcite formations.

This stunning subterranean retreat was built entirely by hand. Tucked under the sun-scorched landscape of Fresno, California, lie the Underground Gardens of Baldassare Forestiere . They are the life’s work of Baldassare Forestiere, a Sicilian immigrant who started digging in the early 1900s to escape the Central Valley's oppressive heat.

Over 40 years, drawing inspiration from ancient Roman catacombs , Forestiere carved an elaborate network of underground rooms, passageways, grottoes, and courtyards that span 10 acres.

A unique masterpiece, the gardens are open with guided tours that lead guests through beautifully designed spaces featuring skylights, arches, and alcoves. This oasis also boasts an array of fruit trees, including citrus, figs, and olives.

Colorful and breathtaking, the Ruby Falls is a geological wonder located inside Lookout Mountain near Chattanooga, Tennessee.

Hidden over 1,000 feet below the mountain's surface, this waterfall cascades 145 feet into a pool , making it one of the tallest underground waterfalls open to the public.

Visitors enter the mountain and descend via elevator. Then, they walk through stunning cave formations such as stalactites, stalagmites, and flowstone. At the waterfall chamber, multicolored lights –powered by renewable energy– illuminate the falls. Lantern-lit tours are also offered as a chance to visit the marvel with a different charm.

Arched tunnels of tranquil, sacred vaults lie beneath the Green-Wood Cemetery in Brooklyn, New York. Built in the mid-19th century, these catacombs were designed as a prestigious resting place for the city’s elite , prominent families.

While the catacombs are typically closed to the public, special events are sometimes organized to welcome visitors, such as art expositions, guided history tours, and candlelit tours seasoned with live music and storytelling.

Outside, where the sun does reach, await the serene landscapes and remarkable monuments of the cemetery, which is itself a National Historic Landmark .

The largest underground lake in America is in Tennessee. Hidden within the Craighead Caverns in Sweetwater, this enormous body of water lies in a cave system filled with fascinating formations, such as stalactites, stalagmites, and rare anthodites, also known as "cave flowers."

A National Natural Landmark, this lake marvels scientists, who are yet unaware of the exact extension of its waters. Those who visit can embark on a boat ride called "The Lost Sea Adventure," first walking inside the cavern before reaching a boat to navigate these ethereal sights.

The Mammoth Cave National Park is home to the longest cave system in the world . Located in central Kentucky, it extends over 420 miles of explored passages and many more likely undiscovered. Enormous chambers, underground rivers, a labyrinth of tunnels, and gypsum crystal formations can all be found at this site.

The park has been declared a UNESCO World Heritage Site and an International Biosphere Reserve. It also includes over 52,000 acres of protected land on the surface, renowned for its lush forests and diverse wildlife.

A large bat colony lives in the Carlsbad Caverns National Park in New Mexico, but that’s not its only charm. The park boasts over 100 caves, with its centerpiece being the immense Carlsbad Cavern.

The cavern includes the Big Room, one of the largest underground chambers in North America, spanning 8.2 acres. Visitors can descend via an emblematic natural entrance or by elevator, dropping 750 feet underground. Stalactite formations like the Giant Dome, the Hall of the White Giant, and the Chandelier are some of the caves' breathtaking highlights.

Indian Echo Caverns

The Indian Echo Caverns, which have been open to the public since the early 1920s, are carved into the limestone of the Appalachian Mountains. Located near Hummelstown, Pennsylvania, this site gets its name from the echoes heard within the cavern’s chambers , which were once believed to be mystical by Native American people in the area.

Unique, immersive sections of the caverns have names like the "Crystal Palace," the "Echo Room," and the "Wedding Room," where, yes, real weddings are sometimes held!

Wind Cave National Park

Image: Francesco Ungaro

Wind Cave National Park, located in the Black Hills of South Dakota, is one of the world’s largest caves, but that’s not what it’s most famous for. One signature sight here is the boxwork formation , a rare lattice-like pattern formed by calcite deposits.

The cave system stretches for over 140 miles, though much of it remains unexplored. Popular tours take guests through captivating features like the "Ribbon Room" and the "Crystal Palace."

Why is Wind Cave called that? Mainly due to the "wind" phenomenon that occurs at its entrance. The cave's air pressure causes the entrance to draw in or expel air, depending on atmospheric conditions.

Levi Strauss

Image: Eric Prouzet

Although his name will forever be associated with American business pioneers, Levi Strauss was not born in the United States. That's right! The inventor of the iconic blue jeans was born in Bavaria, Germany, in 1829. In 1847, he came to America along with his siblings in search of new opportunities, settling in New York. Eventually, he moved to San Francisco, where his famous company would be founded.

Irving Berlin

Image: Sandra Grünewald

While he can be considered one of the most American of Americans, Irving Berlin was actually born in Russia. That's right; the legendary composer and lyricist was born in 1888 in what was then the Russian Empire, and his family immigrated to the US when he was just a child. How lucky for us! Can you imagine life without classics like "White Christmas," "God Bless America," and "There's No Business Like Show Business"? Neither can we!

Alexander Graham Bell

Image: Carlos Eduardo

Although he became a naturalized US citizen in 1882, Alexander Graham Bell was born in 1847 in Edinburgh, Scotland. He arrived in the United States in 1871, where he worked as a teacher and researcher. It was in America, in 1876, that he made his most famous invention: the telephone.

Elizabeth Taylor

Elizabeth Taylor, our Cleopatra, wasn't born in the United States. As you probably know, she saw the world for the first time in England in 1932 and moved to America in 1939, just before World War II started. But here's an important detail: Her parents were American! So, she was a US citizen from birth; she just happened to be born overseas.

5

Alfred Hitchcock

Image: Usha Kiran

Yes, Alfred Hitchcock was born in England, but we probably wouldn't have had the pleasure of enjoying cinema classics like Rear Window (1954), Vertigo (1958), Psycho (1960), and The Birds (1963) if he hadn't come to live and work in America. Although he was already a successful director in his home country, Hitchcock decided to come to the United States in 1939, drawn by the promise of Hollywood's growing film industry.

Audrey Hepburn

Although she became an American citizen in the 1950s and won our hearts on the big screen, the legendary Audrey Hepburn was actually born in 1929 in Brussels, Belgium. In 1945, she settled in England, where she began taking ballet classes and started landing modeling and acting roles. Finally, in 1951, she came to America to star in the Broadway production of Gigi .

Isaac Asimov

Science fiction as we know it wouldn't be the same without the incredible work of Isaac Asimov. However, we may never have had the opportunity to enjoy his brilliant writing if his family hadn't immigrated to America. Asimov was born in 1920 in Petrovichi, Russia. His parents decided to move in 1923, just a year after the Soviet Union was established. At only 3 years old, he arrived in the US, and by the age of 8, he was a full American citizen.

Charles Chaplin

The unforgettable Charlie Chaplin was born in London in 1889. Before he turned 20, he arrived in the US as a young performer with a vaudeville company. Here, he found fame and became a global icon of silent film. Surprisingly, even after living and working here for over 40 years, he never officially became an American citizen, but Americans embraced him wholeheartedly all the same.

Albert Einstein

Albert Einstein, one of the most famous scientists in the world, was born in Germany. And he chose to be American! He was born in Ulm, Germany, on March 14, 1879, and later became a US citizen in 1940.

His first trip to America was in 1921, when he came to New York as a renowned scientist. Then, in 1933, he returned for good and accepted a position at the Institute for Advanced Study in Princeton, New Jersey, where his former house still stands.

Joseph Pulitzer

Joseph Pulitzer revolutionized the press in America and around the world, but before becoming a renowned US citizen, he lived in Hungary, the place where he was born in 1847. At the age of 17, he left Europe in search of greater opportunities and arrived in the US in 1864. Here, he went on to become a pioneering journalist and newspaper publisher, even giving his name to the prestigious awards honoring excellence in journalism and the arts.

The entire coastline is made of glorious sandy beaches

Image: Jeremy Bishop

California’s coastline is long, gorgeous, and wildly varied. Much of it is dominated by cliffs, rocky shores, and chilly waters. Even many popular beaches require a wetsuit if you actually want to get in the water.

Yes, some stretches are ideal for volleyball and sunbathing, but others are better suited to photography.

2

Celebrities are everywhere and happy to mingle

Image: Bibi

It’s tempting to imagine Los Angeles as one giant red-carpet event, but daily life looks a lot more ordinary. Celebrities tend to live in gated communities, travel in private cars, and pick very discreet places to relax.

You might spot one, but you’re far more likely to meet tourists looking for celebrities than actual celebrities themselves.

3

Move to Hollywood and become a star overnight

Image: Edgar Colomba

Hollywood is full of dreamers, but most of them are hustling on the side, waiting tables, doing gig work, and going to audition after audition.

Fame is rarely instant. It’s more like a very long, very competitive marathon that most people don’t see unless they live there.

4

Move to Silicon Valley and become an overnight startup whiz

Image: Nils Huenerfuerst

It’s true that Silicon Valley is packed with entrepreneurs and investors. But it’s also full of failed startups, intense work schedules, and fierce competition.

Raising money is tough, building a product is tougher, and surviving long enough to succeed is almost heroic. The myth of "instant unicorn status" is just like the myth of instant movie stardom.

5

The weather is sunny and perfect year-round

Image: Roberto Nickson

California’s climate varies dramatically. Coastal fog in the Bay Area can last all day, winter rainstorms sweep through the north, inland valleys hit triple-digit heat, and wildfire season is a yearly threat.

6

Traffic is terrible, everywhere

Image: Aleksandr Popov

The traffic horror stories from Los Angeles are quite real, but they’re not universal. California is huge, and plenty of mid-sized cities and rural areas have perfectly manageable commutes. Even in LA, traffic ebbs and flows.

7

Californians go to Disneyland every other weekend

Image: Isaac Garcia

Disneyland may be magical, but it’s also expensive, crowded, and logistically complex. Most residents go once in a while, not as a biweekly ritual. Sure, annual passholders exist, but they’re the exception.

8

You’ll find palm trees everywhere

Image: Mitchell Luo

Palm trees are iconic, but they’re not the dominant tree across the state. Many were imported, and Los Angeles’ famous palms are aging out and not being widely replaced. Walk outside the major tourist zones, and you’ll see oaks, pines, sycamores, and far fewer "tropical vacation" vibes than the postcards suggest.

9

Movies are being filmed on every corner

Image: clement proust

You may stumble across a film crew once in a blue moon, but the vast majority of production happens on studio lots or in specifically chosen neighborhoods. Filming permits are expensive, traffic control is complicated, and spontaneous street-corner movie shoots aren’t as common as people think.

10

Everyone is a surfer

Image: Jacob Steckmann

Surfing is a proud part of California culture, but not a universal one. Many residents have never touched a surfboard, and the cold Pacific waters can be intimidating even for the brave. The idea that everyone wakes up, grabs a board, and runs to the beach is more Hollywood montage than real life.

11

Everyone lives close to the ocean

Image: Jonathan Schmer

California’s population is spread across vast inland regions, including the Central Valley, Sacramento, and the Inland Empire, which are all hours away from the coast. Plenty of Californians only see the ocean during vacation.

12

The food is all organic, clean, and hyper-healthy

Image: Jannis Brandt

Yes, you’ll find green juices, vegan cafés, and farm-to-table everything. But California is also home to drive-thrus, giant burritos, and some of the most indulgent comfort food around. The "everyone eats quinoa and sunshine" trope doesn’t hold up once you explore beyond the trendy spots.

13

Everyone commutes by bike, skateboard, or electric scooter

Image: Hiboy

It looks cool in TV shows, but in reality, most Californians commute by car. Public transportation is limited outside a few areas, and long distances make biking impractical for many.

14

Everything in California is incredibly expensive

Image: Martin Zenker

Housing in places like San Francisco is famously pricey, but California also includes smaller cities and rural communities where the cost of living is much closer to the national average.
