From New England leaf-peeping to big American cities you can afford, plus amazing national parks, European capitals, and Caribbean dreams, we've rounded up our biggest batch of autumn getaways ever. Now your only challenge is deciding which fall vacation to take!

BERKSHIRE MOUNTAINS

If you don't want to have to decide between great museums and relaxing mountain hikes, book a week in western Massachusetts, where you can revel in both. Explore one of the U.S.'s largest collections of modern art at the Massachusetts Museum of Contemporary Art in North Adams; see the comprehensive collection at the Sterling and Francine Clark Art Institute in Williamstown; enjoy the Berkshire Museum in Pittsfield, and step back into 19th-century New England by crossing the border into Bennington, Vt., for the Grandma Moses collection at the Bennington Museum and Grandma Moses Schoolhouse. 

Stay: Holiday Inn Berkshires is in North Adams, Mass., centrally located for dividing your day among art, theater, and nature; there's an on-site restaurant and indoor pool (40 Main St., North Adams, Mass., holidayinn.com, from $119).

NEW YORK CITY

Sure, the city that never sleeps is known for some astronomical prices ($1,000 baseball tickets, $100 hamburgers, anyone?), but this capital of art, music, design, fashion, and finance also offers more freebies (and near-freebies) than any other major city in America. A must-see for families year-round is the American Museum of Natural History, with its awe-inspiring life-size blue whale model, dinosaur fossils on the top floor (or "in the attic," as the staff likes to say), and interactive Discovery Room. In summer, walk the High Line, an elevated park created out of an abandoned stretch of railroad track that offers kids programs with storytelling and sculpture-making. NYC's parks offer free movies and concerts, and a tasty snack is always a block away--nab a classic twisty pretzel from a hot dog stand. 

Stay: The Jane, in Manhattan's West Village, once housed the survivors of the Titanic. You'll feel (almost) as lucky with this nicely appointed hotel's bargain rates. (thejanenyc.com, from $125)

DOMINICAN REPUBLIC

At the Iberostar Costa Dorada, "all-inclusive" means you may not have to reach for your purse the entire stay! And unlike some resorts, this place pours top-shelf cocktails for no extra charge!Hang a do-not-disturb sign on the door of your thatched-roof lodgings! Or indulge in cuisine that includes Brazilian, Mexican, and international menus. Lounge on the beach or beside the massive pool, or get adventurous with kayaking or diving lessons in a tropical paradise. 

Stay: The Iberostar Costa Dorada, just 10 minutes from Puerto Plata, completely renovated its 500+ rooms in 2011; all-inclusive lodging, three a la carte restaurants, and top-shelf drinks from $75 per person per night based on double occupancy (iberostar.com).

GREAT SMOKY MOUNTAINS NATIONAL PARK

America's most popular national park, a major theme park, and miles of trails and streams for under $100 per night? Yep. Head to the Great Smoky Mountains National Park for fishing, hiking, and scenic drives like the six-mile Roaring Fork Motor Nature Trail, and don't forget to spend at least one day at 150-acre Dollywood for authentic Tennessee music, food, and, of course, thrill rides such as the Wild Eagle and Mystery Mine. 

Stay: The Park Vista--a DoubleTree by Hilton Gatlinburg features two restaurants, an indoor pool, and mountain views (705 Cherokee Orchard Road, Gatlinburg, Tenn., doubletree3.hilton.com, from $89).

DUBLIN

Affordable, friendly, and second-to-none in big-city culture and natural beauty. Start your Ireland adventure in Dublin to see beautiful Trinity College, where you can ogle the illuminated manuscript known as the Book of Kells, drink in St. Stephen's Green and Phoenix Park (which has a zoo), and then Riverdance on over to the Guinness Storehouse, which is basically Disneyland for grownups, to drink in--literally--another side of Dublin. Historic Temple Bar is another great place to tip a pint. And since one in nine American is of Irish descent, including President Obama, some like to do a little genealogy research here to see where their family came from. Then get out into the countryside. It's a great place for driving, and you shouldn't miss Connemara, Galway, and other beautiful spots. 

Stay: Dublin boasts some of the most affordable hotels in Europe, and we like the Harrington Hotel (harringtonhall.com, from $91). And for a great package deal to Ireland, visit aerlingusvacationstore.com.

ARIZONA

The Arizona desert sun, spas, and golf courses are warm and inviting in fall, but the crowds stay away. Scottsdale draws visitors for all of the above, and more, but it gets busy and pricey during the winter, when westerners flee the snow to take to the gold courses and watch exhibition Major League Baseball. 

Stay: Book a room at the lovely Wingate by Wyndham, Scottsdale (wingatehotels.com, for around $143, which is $120 less than what it will cost in January).

ATLANTIC CANADA

Step back in time in an 18th century fishing village. Enjoy the friendly locals, freshest seafood EVER, and a European feel right here in North America!Old Town Lunenburg is a lovely 18th-century century heritage site in Nova Scotia. Stroll past brightly colored wood-framed houses painstakingly preserved by Lunenberg's citizens. Buy a $10 ticket to the Fisheries Museum of the Atlantic and its wharves to behold floating replicas of famous trawlers and schooners. Grab an amazing bowl of chowder and traditional Lunenburg fish cakes at local favorite, The Knot Pub. 

Stay: Quaint and cozy, the Smugglers Cove Inn is right by the docks (smugglerscoveinn.ca, from $99).

SAN FRANCISCO

Look up, down, or side-to-side in SF and you'll be greeted with gorgeous waterfronts (the Pacific Ocean and San Francisco Bay), unforgettable architecture (like the multicolored Victorian "Painted Ladies"), and roller-coaster hills that only make the visit for charming, especially for the little ones. Hop on one of the city's classic cable cars for some fun ups and downs on SF's famous hills; you can explore vibrant, unique neighborhoods like Chinatown with a one-day pass ($15). Head to popular Pier 39 on San Francico Bay to ogle the big, adorable sea lions and to grab a taste of a signature Northern Cal fave: clam chowder served in a sourdough bread bowl. Stroll through Golden Gate Park for its knockout botanical gardens, free concerts, and hands-on activites. 

Stay: Hotel Del Sol is a family-friendly hotel with vibrant design and a great location in the Marina/Cow Hollow area. Perks include afternoon cookies and milk, heated pool, and free breakfast (jdvhotels.com, from $120 per night).

BARCELONA

Party central for kids and grownups--and all for the same reason! It's just a high-energy city that looks like a fairytale thanks to its imaginative architecture. Visit the Sagrada Familia Cathecdral designed by Gaudi and La Rambla, a major avenue where you'll get a taste of Barcelona's exuberant culture and shopping. Barcelona is also home to tapas, which basically means your dinner is made up of endless appetizers. What's not to love? 

Stay: Chic & Basic Ramblas, which looks way cooler than its name (chicandbasic.com/en, from $141). Or, for a great package deal to Barcelona, visit friendlyplanet.com.

LAS VEGAS

If you're thinking that Las Vegas is just for bachelor parties, girl getaways, and high rollers, you're in for a pleasant surprise. The city's major hotels and venues are wooing families with kids with low prices and tons of fun. Viva Vision Light Show at the Fremont Street Experience is a lively music and light show on a projection screen the length of five football fields suspended 90-feet above you. Circus Circus offers free acts like jugglers, trapeze artists, and acrobats all day long.

Stay: Our Real Deals section typically offers Vegas hotels for under $50.
