20 Best Museums in the USA
Art Museums
1. The Metropolitan Museum of Art – New York City, NY
Located in New York City, one of the essential US travel cities, The Metropolitan Museum of Art is a true treasure trove of art and history. Picture walking around and stumbling across Egyptian mummies and then some works of the Impressionists.
It is the largest art museum in the United States and every time I go, I get lost in history. Be sure not to miss the Temple of Dendur or the Van Gogh and Monet collections.
2. Art Institute of Chicago – Chicago, IL
The chance to see iconic works like American Gothic and Nighthawks in the flesh. There’s a little something for everyone in this sprawling collection, making the Art Institute of Chicago a great way to spend an afternoon.
But don’t spend the whole time in the museum — the building is also architectural stunning, so take a minute to admire it. And go on a weekday morning to avoid the later crowds.
3. Museum of Modern Art (MoMA) – New York City, NY
If you are interested in modern and contemporary art, this museum is definitely worth a visit. It houses some of the world’s most important artworks, including pieces by Salvador Dalí, Andy Warhol, and Jackson Pollock.
Unlike the famous Florence Italy museums , known for their collections of Renaissance masterpieces, Museum of Modern Art offers a completely different perspective, showing how art evolved toward avant-garde and bold expressions in the 20th century.
There’s even a Van Gogh’s Starry Night. I recommend buying tickets in advance to avoid lines, as they get long, especially on weekends.
4. Getty Center – Los Angeles, CA
In the Getty Center, art gets paired with incredible architecture and awe-inspiring views. In addition to the artworks found within, the building is itself a masterpiece overlooking the LA landscape.
Be sure to also wander the magnificent gardens too. Go on a sunny day to take in sweeping panoramic views.
5. San Francisco Museum of Modern Art (SFMOMA) – San Francisco, CA
For any modern art lover on the West Coast, SFMOMA should be at the top of the list. The modern, open museum space is home to masterpieces by Frida Kahlo and Jackson Pollock, among others.
The museum itself sits in the center of San Francisco, easily accessible from anywhere in the city. It’s worth spending a few hours in these incredible exhibits.
History & Cultural Museums
6. Smithsonian National Museum of American History – Washington, D.C.
This museum is a great place to explore how old America is, with exhibits that trace the nation’s journey from its founding to the present. You can see many famous pieces here, such as the Star-Spangled Banner and the inaugural gowns of the First Ladies.
The museum is free to visit, making it a perfect activity for budget-conscious travelers in Washington, D.C.
7. National Museum of African American History and Culture – Washington, D.C.
This museum is a powerful walk through African American history and culture.
The exhibits are detailed, powerful, and emotionally moving across a variety of topics from slavery and civil rights to today. However, be sure to get your tickets in advance, as demand is insane.
8. The Henry Ford Museum – Dearborn, MI
You’re going to spend the day exploring American ingenuity at The Henry Ford Museum. From classic cars to life-changing creations, it’s a wonderful showcase of the country’s manufacturing history.
Don’t miss the Rosa Parks Bus and the other hands-on displays. This is a great place to visit with kids. You could spend the entire day here.
9. National WWII Museum – New Orleans, LA
Explore the stories and history of World War II in this incredible, immersive museum. It’s a pretty intense museum, too, complete with lots of personal stories and historical equipment.
They’ve created some very realistic exhibits that will give you a sense of the weight of the global war. A tour may help you dissect it all.
10. The 9⁄11 Memorial & Museum – New York City, NY
This museum serves as both a memorial and a history lesson. The stories of the victims of the 9/11 attacks are deeply moving and thought-provoking, leaving a strong emotional impact. Like other well-known US monuments, it embodies the nation’s memory and represents resilience and reflection in the aftermath of tragedy.
The memorial pools outside are a very moving experience. For a quieter and more tranquil visit, come at night when the pools are beautifully lit.
Science & Technology Museums
11. Smithsonian National Air and Space Museum – Washington, D.C.
If you’re at all interested in airplanes and space, the Smithsonian National Air and Space Museum isn’t to be missed. They have historic planes here (including the Wright brothers’ flyer) as well as the Apollo 11 command module.
Don’t miss the Space Walk and the interactive displays. For fewer people, visit on a weekday and take a tour to really understand what you’re seeing.
12. California Science Center – Los Angeles, CA
The California Science Center is home to the Endeavour space shuttle (try to wrap your head around how big that is).
If you have kids, this is the museum for you as there are tons of interactive exhibits that are fun and educational for all ages.
The IMAX and ecosystem exhibits are particularly cool. Try to visit during the week, in the afternoon, when there are fewer school groups.
13. Museum of Science – Boston, MA
The Museum of Science in Boston has something for everyone, and it’s all hands-on educational. From dinosaur bones to a planetarium, it’s pretty impressive.
It’s definitely for kids, but adults can appreciate the cool displays as well. You should spend a few hours here, and be sure to catch at least one of the daily demonstrations.
14. The Franklin Institute – Philadelphia, PA
The Franklin Institute in Philadelphia is a fun way to teach science. For example, it has a walkthrough heart for you and your children to explore! It’s very family-friendly (but adults will enjoy themselves too).
Don’t miss the outstanding science museum or the observatory here. For the whole family – be sure to see a temporary exhibit if there is one!
You’ll skip waiting in line too if you order tickets in advance so you’re not standing around during the busy times.
Natural History & Nature-Focused Museums
15. American Museum of Natural History – New York City, NY
Dinosaurs, the ocean, and space—all in one place. The American Museum of Natural History has it all. It’s a fun place to explore and good for kids too. Don’t miss the giant blue whale or the T. rex fossils.
Weekdays mornings are the best time to visit as it’s less busy and it’s pay what you wish so it’s super affordable.
16. Field Museum – Chicago, IL
The Field Museum in Chicago is home to the largest T. rex, “Sue.” The museum has some really cool information about different species and civilizations of the past.
In addition to Sue, it also has Egyptian mummies and a planet exhibit about trees. Going during the week is a great way to avoid the weekend crowds and enjoy peace and quiet.
17. Denver Museum of Nature & Science – Denver, CO
The Denver Museum of Nature & Science is a great way to mix some natural history with some views as it has much to offer, from dinosaur bones to out of this world space exhibits.
Plus, it has a couple of cool IMAX movies and a T. rex exhibit too. Go early in the am or later in the pm to avoid the crowds.
Unique & Niche Museums
18. The Museum of Pop Culture (MoPOP) – Seattle, WA
If you are visiting Seattle and are a fan of pop culture, you shouldn’t miss MoPOP. It houses music, movie, and video game displays and is in a cool sci-fi building.
The Nirvana and sci-fi exhibitions are particularly enthralling. Visit on a weekday so you have the space to enjoy everything and won’t have to deal with as many people as on weekends.
19. The Salvador Dalí Museum – St. Petersburg, FL
Explore the bizarre universe of Salvador Dalí at this museum in Florida. His works number over 2,000 and with essence both mesmerizing and strange, arty types will definitely dig it.
The museum organizes one-of-a-kind events and has themed activities too, so be sure to look at the calendar before going. After going through the indoor portion of the museum, take a walk inside the tranquil garden area.
20. The Neon Museum – Las Vegas, NV
The Neon Museum in Las Vegas is home to old Vegas signs, and it’s a pretty cool walk down memory lane. Especially since you can see the vintage signs lit up.
I recommend visiting after dark so you can get the full effect and see all the signs lit up! Just make sure to book your tickets online in advance. They sell out fast, and there is a ton of demand.
Tips for Visiting Museums in the USA
Visiting museums during off-peak hours is a great way to avoid long lines. Compared to busier times, weekdays or mornings tend to be quieter, making it easier to explore at a relaxed pace.
In a calmer setting like this, you can focus more on the exhibits and fully immerse yourself in the experience, without the distractions of crowds and noise.
Having reliable U.S. travel data is just as important. It ensures smooth internet access inside the museum, making it easy to check maps, browse exhibit information, and adjust your plans on the go. Whether you're using audio guides, booking exhibitions, or sharing moments from your visit, a stable connection helps keep everything seamless and stress-free.
Taking advantage of free admission days is another smart way to save money. Many museums offer free entry on certain dates, so planning ahead can help reduce travel costs while allowing you to visit more places.
As for how long to spend in a museum, it really depends on the individual. For some, a couple of hours is enough—but pacing is key. Staying too long can lead to fatigue, while leaving too early might mean missing out on highlights. Finding a rhythm that works for you is the best approach.
Think about the experience you want: Some museums are designed with families in mind, providing hands-on and interactive displays for children. Others target adults, making for a quieter and more reflective trip.
If you know what you prefer in advance, it will be easier to find the best museums.
Lastly, don’t forget about accessibility. A lot of museums now have guided tours, which not only give you more in-depth information but also make it easier for people who have trouble moving around.
They usually share some interesting information that you won’t get exploring on your own, too, making the experience better.
FAQ
1. Are there any museums with free admission days?
If you’re considering a visit to the museum, many museums have free admission days. In Washington, D.C, you can visit all of the Smithsonian museums for free. I’ve also seen City Passes in different cities for budget-friendly visiting.
2. Are guided tours available in museums?
Yes, most museums have guided tours. I often recommend taking them as you learn more and it helps you get your bearings (which is important in larger museums and when you’re short on time).
