A treasure trove of Americana, the Walmart Museum is currently occupying a building two blocks south of its normal location thanks to a renovation project. But when it reopens later this year it will return once more to the original Walton’s five-and-dime store (it was Sam Walton's second property, but the first to bear his name) that started it all in Bentonville Square. It will feature state-of-the-art exhibits including interactive holograms alongside vintage gems, plus an on-site 1950s diner serving up local pie and ice cream.

There’s always plenty to do indoors and out in America's most populous state. In Los Angeles the Getty Center is the go-to spot for a cultural fix on a rare LA rainy day, and further north San Francisco has just as much to offer. Less well known but with a much longer history, this year marks the centennial of artistic powerhouse the Legion of Honor Museum. Special exhibitions feature alongside its huge collection of French Impressionist masterpieces, Ancient Greek sculptures, millennia-old Egyptian artifacts and more.

Colorado has a solid record of year-round sunshine that makes it one of the better outdoor destinations in the US, but there are plenty of fun and interesting places to go when the weather turns. An hour from Denver, seek shelter at the century-old Stanley Hotel – the spooky setting for Stephen King’s The Shining. On the National Register of Historic Places, it hosts themed tours showcasing its history, filming spots and its many ghost stories, and includes an International Cryogenics Museum among its collection of strange features.

The former home of one of America’s greatest authors, Mark Twain (real name Samuel Clemens), is now a well-preserved Gothic gem that’s stuffed with fascinating artifacts from the writer’s life.

An accompanying museum delves deeper into his life and works with permanent and rotating exhibitions.

'When it rains, we pour!' declares a sign at the Dogfish Head Milton Brewery – a sweet spot on a wet day in Delaware with 40-plus taps to sample in the tasting room, and plenty else to do throughout the premises. Tour the sprawling 200-barrel brewhouse and the steampunk treehouse, or try an experimental brew and scratch-made cocktail. You won’t go hungry either as the kitchen serves up casual tasty plates.

Even the Sunshine State has the occasional rainy day. If you’re looking for Florida fun during a downpour, make a beeline for WonderWorks, an upside-down indoor amusement park aimed at families in Orlando, where weird science and magical illusions collide. There are more than 100 hands-on exhibits: get zapped by a Tesla coil, endure a 5.3-magnitude earthquake and experience weightlessness in a two-person gyroscope. Upstairs – in 'the basement' – there's a glow-in-the-dark ropes course and a laser tag arena.

Music is woven into the fabric of Georgia, where stars like Little Richard and Otis Redding were born and got their starts, so it’s fitting the state should amp up its thriving music scene with the opening of the new Classic Center Arena this summer. The state-of-the-art venue will be equipped to host everything from major concerts to ice hockey, and the concourse will display exhibits from the Georgia Music Hall of Fame.

Always warm, Hawaii is still prone to a tropical downpour, and the hallowed halls of Iolani Palace are particularly appealing on a rainy day. As the only US state with royal pedigree, this grand palace in downtown Honolulu is the only former royal residence in the entire country. A proud symbol of Hawaiian identity once home to King Kalakaua, who built the palace in 1882, the mansion’s opulent interiors reflect royal life in the 19th century. A room-by-room audio guide fills visitors in on its rich history.

A whole museum dedicated to the humble spud may sound unusual, but not in Idaho, which leads the nation in potato production to this day. Housed inside an old railroad depot built in 1913, the Potato Museum is a really fun little enclave in the small town of Blackfoot. Inside you’ll find antique machinery, memorabilia, science experiments and what is apparently the world's largest potato chip (25 by 14 inches), plus a cute cafe where you can tuck into delicious Idaho potatoes, whether baked or fried.

The self-proclaimed 'largest science center in the Western Hemisphere', the Museum of Science and Industry offers oodles of fun on a blustery day in the Windy City. Dating back to 1893, its enormous proportions are perfect for housing locomotives, boats, rockets and planes, and kids will love the interactive exhibits. Highlights include the chance to explore the interior of a Second World War submarine, a dizzying mirror maze and a vast model railroad.

You could stay indoors when Indiana’s climate gets too cold, or you could flee underground to the awe-inspiring Indiana Caverns. Part of a 'family adventure park', Indiana's largest cave system stays steady at a clement 56°F year-round, and tours run rain or shine. The dramatic stonescapes are draw enough – at their best during a 20-minute boat tour on a subterranean river – but the caves also offer Ice Age fossil-viewing and underground escape rooms.

You’ll be stunned by the stellar collection of artworks at the beautiful multi-story Figge Art Museum in Davenport.

Tucked into America's northeastern corner, it can get mighty cold in Maine come winter.

The museum showcases classic and contemporary art from the US and Europe – from Andy Warhol to Renoir – and highlights Maine’s artistic legacy alongside a packed schedule of temporary exhibitions and screenings. There are currently plans for a $100 million expansion project, which should add 60,000 square feet (5,600sqm) to the museum.

On a typically rainy day in Baltimore explore this treasure house of priceless artworks and antiquities in the heart of the city.

Mummies, mosaics, statues and paintings are all housed in the grand galleried building with an impressive winding staircase and atrium.

To lift your spirits on a gray day, head to downtown Springfield to peruse the Springfield Museums, a five-for-the-price-of-one bundle of institutions covering art, science, culture and storytelling.

Fun for all the family, interactive exhibits include rhyming games, a giant marble maze, a Lorax-themed recycling game and Geisel’s reconstructed studio.

Music and motoring are part of Detroit’s fabric, and with smart attractions dedicated to both, where you head on a rainy day comes down to personal preference. Fans of classic cars should head to The Henry Ford (a three-in-one bonanza of vehicular history), but if you like Motown don’t miss the museum and recording studio where it all began. With testimonies from Beyonce and the Beatles, tours immerse visitors in soulful music in the small venue once known as Hitsville USA, surrounded by artifacts belonging to greats like Marvin Gaye and the Supremes.

With its eclectic exhibits, rotating showcases, film screenings and subject matter ranging from the First World War to the history of toys, the Durham Museum, housed within Omaha’s grand former Union Station, has plenty to please everyone on a rainy Nebraska day. Recent exhibitions include LEGO’s Towers of Tomorrow piece, which served up elaborate LEGO constructions of the world's most famous skyscrapers, and a costume showcase featuring wardrobes from popular TV series Downton Abbey.

It’s more likely to be desert heat than cold and rain that drives you indoors in Nevada, but luckily the state’s main attractions are largely all-weather friendly.

Head indoors for thrills, spills and competitive prices at the American Dream megamall in New Jersey. The second largest mall in the US shelters an entire theme park, Nickelodeon Universe (not to be confused with Minnesota's indoor theme park of the same name), complete with looping roller coasters, plus a Dreamworks-themed waterpark with rides and slides. Throw in a Ferris wheel, a large ice rink, an aquarium, a surf pool and two types of minigolf, and this climate-controlled entertainment hub will make you forget what season it is outside.

This year, see iconic spectacles from New York Knicks games to Jerry Seinfeld live shows.

The very best attractions for American sports fans

This is the most eccentric attraction in every US state

One of the oldest cities in America, Charleston reverberates with heritage and history. Head indoors to discover its past at a handful of spots in the Historic District. Seek out quintessential Southern charm at the 200-year-old roofed City Market, stuffed with handmade wares including Charleston’s famous sweetgrass baskets, before exploring the opulence of the grand Nathaniel Russell House Museum. That's in stark contrast to the Old Slave Mart Museum, a former slave auction site that now details its horrible history.

Strewn with prehistoric marvels, South Dakota offers some of the richest fossil beds on earth. When the skies open, get out of the elements and up close to natural history at the active indoor dig site at Hot Springs, where the bones of countless Ice Age animals like wooly mammoths, giant short-faced bears and prehistoric camels are still being unearthed. Many of the mammoth bones are still displayed in-situ in the 'bone bed'.

These are the most beautiful temples on Earth

Vermont’s sweetest spot for a rainy day has to be the flagship factory of world-famous ice cream brand Ben and Jerry’s.

The original ice cream factory, it's the only one open to the public and includes a cute 'scoop shop' and gift store, as well as an amusing ‘flavor graveyard’ of varieties no longer in production.

Beyond its spectacular scenery, Virginia’s most prominent feature is its history. The site of the first English settlers in North America, it was also a key state in the Revolutionary War and the birthplace of first president George Washington.

The Appalachian Mountains are pitted with elaborate caves and old mines. Escape the West Virginia weather and enter a whole other world at the aptly-named Lost World Caverns near Lewisburg. Descend 120 feet (37m) underground to one of the most beautiful commercial caves in the eastern US. You can take a self-guided walking tour to explore its halls hung with stalactites – this takes around 45 minutes at a steady 52°F. Four-hour Wild Cave Tours are available for the more adventurous, plus there’s a small museum full of dinosaur and fossil specimens.

Wisconsin has been big on beer since German settlers arrived in the 1830s, and there are more than 200 breweries spread across the state. The Miller Brewery is one of the oldest and most established. What better excuse than a spell of bad weather to go on a tour of its brewhouse and underground cold storage caves, and sample some of its finest beers in the Bavarian-style Miller Inn – or, if the rain clears up, an outdoor beer garden.

The renowned National Museum of Wildlife Art is one-of-a-kind, knitted into the rugged hillsides of Jackson Hole with stone galleries showcasing fine art and sculpture inspired by nature. The sculpture trail is outdoors and best viewed with good weather, but otherwise it offers the perfect spot to connect with the wild in warm and sheltered surrounds. Featuring works by artists ranging from John James Audubon to Andy Warhol, it has wildlife photography exhibitions as well as more conventional fine art.
