What is it? Immaculately maintained by the National Park Service, the National Mall and Memorial Parks feature more than 1,000 acres of must-see monuments, sites, and green space. While the Washington Monument towers above all else—quite literally, the city doesn’t zone for buildings taller than the marble icon—the Lincoln Memorial, Thomas Jefferson Memorial, Vietnam War Memorial and Martin Luther King Jr. Memorial are just as magnificent.
Why go? It will take a full day (or two) to see the National Mall—not only can you take in the grandeur and history on display at the monuments, it also gives you easy access to check out some of Washington, D.C.’s top museums.
2. Niagara Falls | New York State

What is it? Situated on the border of New York and Canada, the three waterfalls (Horseshoe Falls, American Falls and Bridalveil Falls) that make up Niagra Falls have the combined highest flow rate of any waterfall worldwide. Their impressive force is nothing short of awe-worthy.
Why go? A top tourist destination since the 19th century, the unstoppable beauty and charm of Niagara Falls make it a memorable and unique landmark.
3. The French Quarter | New Orleans, LA

What is it? The oldest corner of New Orleans remains its most charming attraction. Walk down famous Bourbon Street to enjoy jazz, great nightlife and tons of food.
Why go? While you travel on a streetcar between destinations, pay close attention to the spectacular architecture. And no trip to the French Quarter would be complete without a taste of authentic Cajun grub or a stop to pay your respects in the Cities of the Dead.
4. Statue of Liberty | New York City, NY

What is it? Though she may have been born in France, the Statue of Liberty has become synonymous with America and the country’s highest-held values.
Why go? The 151-foot-tall copper monument is worth seeing up close from aboard the free Staten Island Ferry, but you can also pay your respects in person and even step inside it while on an official tour.
5. Old Faithful | Yellowstone Park, WY

What is it? A cone geyser found in Yellowstone National Park, Old Faithful is not entirely as predictable as it once was (it won’t erupt precisely every 74 minutes, for example) yet remains as historically exciting.
Why go? When erupting, the geothermal feature unleashes more than 3,700 gallons of piping hot water. When you’re done marveling at the spectacle, spend at least a full day exploring the rest of the park.
6. Mt. Rushmore | Keystone, SD

What is it? A key road-trip destination in the Midwest, Mt. Rushmore is a historic monument that pays homage to four U.S. presidents: George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln.
Why go? Marvel at the work that had to go into achieving this feat—nearly 90 percent of the mountain was carved using dynamite, built by more than 400 men from 1927 to 1941. Also, the trip will be an opportunity to learn about the controversial history of Mt. Rushmore, which is built on sacred Native American land.
7. The Strip | Las Vegas, NV

What is it? Immortalized in a seemingly endless amount of movies, the Las Vegas Strip’s bright lights, larger-than-life performers and casinos are burned into our collective subconscious.
Why go? Whether planning on trying your luck at poker or looking to catch a diva’s residency, the Strip is a top destination for all things entertainment and, yes, a bit of debauchery.
8. Smithsonian Museums | Washington, D.C.

What is it? The Smithsonian Institution is the world's largest museum, education, and research complex. Located in the heart of this nation's capital, you can explore the National Air & Space Museum, the National Museum Of Natural History, the National Museum of American History, and many more. The best part?
Why go? It's all free. The latest addition to the museum lineup, which opened in 2016, is the National Museum of African American History and Culture, which is a must-visit.
9. The Grand Canyon | Arizona

What is it? So, about five to six million years ago, the Colorado River more or less established its route through the Arizona desert. Glacial erosion, meltwater runoff and the simultaneous counter effect of the land slowly rising—as the weight of the glaciers was reduced—ultimately resulted in one of the most spectacular natural wonders on our modest, little blue-green planet. The Grand Canyon is 277 miles long, varies between four and 18 miles wide and has a maximum depth of 6,000 feet.
Why go? There are hotels and restaurants in key locations, but for the most part, you should visit and marvel at how incredible this world is—you know, before we ruin it.
