1. Cape Cod

Summers in Cape Cod, just an hour outside Boston, are known for beautiful beaches, starry nights and delicious seafood. Make it a family affair or a cozy getaway for two—this Massachusetts hot spot has something for everyone.
To Do: Go to a Cape Cod League baseball game. College all-stars play in the nation's premier amateur league, which has launched the careers of many professional athletes. Games are free and played at small local fields, so they have the comfy Little League atmosphere with some major-league talent.
To See: The Cape Cod National Seashore encompasses almost 40 miles of beaches and trails on the eastern edge of the Cape—the view from the 155-year-old Highland Lighthouse is a must-see.
To Eat: You can't go to New England in summertime without indulging in seafood. Try a cup of clam chowder or tie on a bib and take a crack at a fresh lobster.
To Stay: Chatham is centrally located and the easiest home base for touring Cape Cod. But be warned, the town's quaint charm and island feel may mean you'll never want to leave.

 2. Chicago

It may be the Windy City, but Chicago has more to offer than just cold and snow. When it comes to warm weather, Chicagoans prove that absence makes the heart grow fonder! Come summertime, locals head outdoors to enjoy a day at the beach, a bike ride along the lakefront or a picnic in any of the city's 7,300 acres of parkland—more than any city in the U.S.
To Do: Tap into your animal instincts at the Lincoln Park Zoo. It's free, and it houses 230 different species of animals. Finish the day with a ride in the swanlike paddle boats or take a turn on the Endangered Species Carousel.
To See:: Enjoy the view from the Skydeck at the Sears Tower, the nation's tallest building. On a clear day, you can see across Lake Michigan into Indiana, Michigan and Wisconsin.
To Eat:: The Windy City is famous for its pizza—deep dish, of course. It was invented at Chicago's Pizzeria Uno in the early '40s. Today, mouthwatering variations on the pan pizza theme abound.
To Stay:: Book a hotel overlooking the lake—you'll get a priceless view with some fun people-watching on the side.

 3. Graceland

Elvis Presley's Memphis, Tennessee, home is the second-most visited house in the United States (after the White House), but you don't have to be a groupie to get all shook up by the King's castle.
To Do: Take the house tour—even if your kids haven't heard of Elvis, they'll get a kick out of the flashy décor and flamboyant costumes. Round out your musical adventure with a trip to Memphis's Rock 'n' Soul Museum.
To See:: Elvis's famed Pink Cadillac in the Car Museum, his collection of gold records and career memorabilia in the Trophy Room and his two custom jets are favorite sights on the grounds tour.
To Eat:: Try the King's favorite—peanut butter and banana sandwiches—or get some Southern flavor with a taste of Memphis barbecue.
To Stay:: If you want to really immerse yourself in Rock 'n' Roll, you can stay at—where else?—the Heartbreak Hotel.

  4. Grand Canyon

Located in the northwest corner of Arizona, the Grand Canyon is a landmark you have to see to believe. At one mile deep and 277 miles long, the canyon attracts about 5 million visitors each year.
To Do: Hike the Bright Angel Trail, the most popular route into the canyon and—since it's equipped with water, rest rooms and lots of shade—the most comfortable path in the summertime.
To See: The sheer size of the canyon is awe-inspiring; one look over the edge and you'll see why it's worth the trip.
To Eat: Forego restaurants and experience the beauty of the canyon with a sunset picnic on the Canyon's rim.
To Stay: There are plenty of lodging options inside Grand Canyon park, but plan ahead! Rooms fill up six to 12 months in advance. To save money, stay outside the park in the cities of Williams, Flagstaff or Cameron.

 5. Mount Rushmore

Summer's biggest holiday celebrates the birth of the nation, so what better way to show your patriotism than heading to South Dakota to visit Presidents Washington, Jefferson, Lincoln and Roosevelt (Theodore, that is)?
To Do: Go to the night show at the memorial's outdoor amphitheater, which includes a talk from a park ranger, the film Freedom: America's Lasting Legacy and the lighting of the memorial.

To Eat: There's only one restaurant at the park, so consider brown-bagging it.
To Stay: Rapid City, about 25 miles from Mount Rushmore, has a variety of places to stay no matter your budget.

 6. San Francisco 

It may seem counterintuitive to head to California to escape the heat, but San Francisco is known for its breezy summers. An average temperature of 70 degrees makes it the perfect family destination, so lace up your sneaks—this bay area gem is best seen on foot.
To Do: Take a bay cruise to Alcatraz, the legendary maximum security prison that once housed Al Capone. An audio tour of The Rock, which operated from 1934 to 1963, is a favorite of adults and kids alike, especially the captivating tales of inmates who tried to escape.
To See: Known as "the crookedest street in the world," Lombard Street is a block full of hairpin turns at an incredibly steep incline. Driving down it can be a traffic nightmare, but walking it is a great time—and a great workout!
To Eat: San Francisco is a culinary playground, but, as any local will tell you, if you only eat one thing, make it a burrito. Taquerias are plentiful, and most serve irresistible authentic burritos for only a few dollars each.
To Stay: Pass on big hotels in Union Square—a popular, but mostly theatre- and business-filled district—for a smaller bed-and-breakfast in the Marina neighborhood.
For more information, visit San Francisco's official website.

 7. Santa Fe

Immerse yourself in culture in this Southwestern city known for its Native American-inspired art and architecture. The breathtaking scenery is an ideal backdrop for hiking, biking or rafting (or simply watching the sunset), and summertime—when the weather is dry, sunny and mild—is the best season to visit.
To Do: Explore the Palace of the Governors, built in 1610 as New Mexico's government building and now the state history museum. Start your day with a Santa Fe history lesson in the museum, then walk along the south side of the palace, where Native American artisans representing 41 different tribes sell handmade goods.
To See: Santa Fe is perhaps most famous as the home to artist Georgia O'Keefe, and the museum dedicated to her art is the sight to see in Santa Fe. The permanent collection houses almost 3,000 of her works, and you don't have to be an art connoisseur to appreciate their beauty.
To Eat: New Mexican cuisine is a variation of Mexican food, but it distinguishes itself most notably with its heavy use of green chilies. While you're in town, try the classic New Mexican dish of Frito pie—a mixture of fritos and chili.
To Stay: Pass on the pricier hotels of downtown Santa Fe and head about five miles north, where hotel options, varying from full-service spas to cozy bed-and-breakfasts, are just as pleasant but much more affordable.

  8. Washington D.C.

Hit the nation's capital for the ultimate double whammy—education and leisure. You're never too old—or young—to appreciate the rich history the city has to offer, and Washington, D.C., has perfected the art of making learning fun.
To Do: Sign up for Operation Spy at the International Spy Museum. See if you can crack the case as you take on the role of a U.S. intelligence officer on an international mission that's based on real-life case files.

 9. Colonial Williamsburg

Travel back in time to the 1770s when you visit this historic district of Williamsburg, Virginia. Leave your TVs and iPods behind while you chat with historical re-enactors who talk, dress and work as they would have in the days of the American Revolution.
To Do: Meet George Washington or Thomas Jefferson when you visit Revolutionary City, an interactive street theater that combines short skits with streetwide events. You'll be a part of the action—be it the collapse of the royal government or the creation of a nation.
To See: Political buildings and colonial homes make for fascinating sightseeing. Highlights include the printing office and bindery, the blacksmith and the governor's palace.
To Eat: Dine at a restored 18th-century tavern. The wait staff wears the clothing of the time period, and you can eat old-school dishes like Welsh Rarebit and Pottage Pye (for pickier eaters, the taverns offer some more modern fare).

 10. Yellowstone National Park

Yellowstone, located in Wyoming, Montana and Idaho, was founded in 1872, making it the country's first national park. In its 2.2 million acres of wilderness, Yellowstone is home to hundreds of species of wildlife and 300 geysers, most notably Old Faithful.
To Do: Go on a hike in the early morning, when animals—including bison, elk and mountain goat—are most likely to be feeding in public view.
To See: Old Faithful, located in the Upper Geyser Basin in south Yellowstone, erupts about every 90 minutes, shooting up to 8,400 gallons of boiling water approximately 150 feet in the air.

To Stay: Make a reservation early to camp out in one of the park's 12 campgrounds.
