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.

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.

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.

What is it? Perhaps the best example of America’s building prowess in the first half of the 20th century, this dam remains a bewildering feat of engineering and labor. Construction started in 1931 and took five years, 5,000 workers and 3.25 million cubic yards of concrete to complete.
