San Francisco is one of the most fascinating cities in the world. From its iconic landmarks to its unique culture, this city holds surprises at every turn. Many people know about the Golden Gate Bridge and Alcatraz, but there are some lesser-talked-about facts that make San Francisco even more intriguing. Before we dive deep into these facts, let’s take a look at some quick stats about this extraordinary city.
| Fact Category | Statistical Insight |
| Population (2024) | ~815,000 people |
| Annual Tourists | Over 25 million |
| Foggy Days Per Year | Around 108 days |
| Number of Hills | More than 50 |
| Cable Car Lines | Only 3 left |
1. The City is Built on Over 50 Hills
People think San Francisco has just a few famous hills like Nob Hill and Twin Peaks, but in reality, it has more than 50! That’s why walking here can be a serious workout. Some hills are steep enough that streets have stairs instead of sidewalks. If you ever find yourself huffing and puffing while walking up, just remember, it is not you, it is the hills.
2. The Golden Gate Bridge Was Almost a Different Color
Today, the Golden Gate Bridge is famous for its “International Orange” color, but it was almost painted black and yellow stripes to ensure visibility for ships. The engineers finally decided on the orange primer because it blended well with the natural surroundings while also being visible through the fog. Good choice, right?
3. San Francisco’s Fortune Cookie Factory Still Makes Them by Hand
Chinatown in San Francisco is home to the Golden Gate Fortune Cookie Factory, where they still fold fortune cookies by hand. The factory has been operating since 1962, and if you visit, you can even watch how they shape the cookies and write custom fortunes for yourself. Most people don’t realize that fortune cookies were actually invented in San Francisco, not China!
4. The City Moves 2 Inches Every Year
San Francisco is slowly drifting toward Los Angeles, moving about two inches every year due to the movement of tectonic plates. The famous San Andreas Fault is responsible for this, and while it’s slow, it’s a constant reminder that California is earthquake territory.
5. Lombard Street is Not the Crookedest Street
Lombard Street is world-famous for its eight hairpin turns, but it’s not actually the most crooked street in San Francisco. That title goes to Vermont Street in the Potrero Hill neighborhood, which has even sharper curves. Yet, Lombard remains the most photographed because of its beautifully landscaped gardens.
| Street | Number of Turns | Famous For |
| Lombard Street | 8 Hairpin Turns | Tourist Spot |
| Vermont Street | 7 Sharper Turns | Less Crowded |
6. Mark Twain Probably Never Said That Famous Quote About SF Weather
The quote, “The coldest winter I ever spent was a summer in San Francisco,” is often attributed to Mark Twain, but there is no actual record of him saying it. Still, anyone who has visited in July knows how true it feels. Thanks to the famous fog (nicknamed Karl), summer here can feel colder than expected.
7. The Largest Chinatown Outside Asia
San Francisco’s Chinatown is the oldest and largest in North America. It was established in the 1840s and has remained a vibrant cultural hub. Even today, you can step inside and feel like you’ve entered another world. From traditional herbal medicine shops to dim sum restaurants that have been serving for generations, it’s a piece of China in the heart of California.
8. The First Electric TV Was Invented Here
Philo Farnsworth, the man who invented electronic television, created the first working model in San Francisco in 1927. Imagine how different the world would be if that invention hadn’t happened! It’s one of those lesser-known facts that highlight how innovative this city has always been.
9. Alcatraz Once Had Some Unusual Residents
Alcatraz is famous for housing notorious criminals like Al Capone, but few people know that it was once home to military families and children before becoming a federal prison. After the prison closed, the island was taken over by Native American activists in 1969 in a historic occupation that lasted for almost two years.
10. You Can See the Remnants of the Gold Rush in the Streets
During the California Gold Rush, the city grew rapidly. Ships were abandoned in the harbor as people rushed to find gold. Many of those ships were buried under landfill, and today, parts of the Financial District are literally built on top of them. If you ever walk down streets like Montgomery or Battery, know that you might be standing over a hidden piece of history.
