A little-known wonder in northeastern Alabama, Cathedral Caverns State Park has been welcoming visitors since the Fifties. One of the largest stalagmites in the world is hidden inside – the aptly named "Goliath" soars to 45 feet (14m), with a 243-foot (74m) circumference. But what really wows is the cave's mammoth opening. According to Guinness World Records, it's the largest in the world, spreading out 126 feet (38m) in width and 25 feet (8m) in height.
Mighty Denali needs little introduction. Rising from its namesake national park, the grand peak tops out at 20,310 feet (6,190m), soaring above forests, alpine tundra and glittering lakes.

Wedged on either side of Tucson is Saguaro National Park, a dramatic swathe of the Sonoran Desert home to epic sunsets and even more epic flora. The park is well-known for its towering cacti, billed as the largest found anywhere in the States. The tallest ever recorded was 78 feet (24m) and today trails beat a path among these spiny giants. You'll find giant Saguaro cacti at Organ Pipe National Monument too.
The stark, stifling plains of Death Valley hold the record for the hottest air temperature ever recorded. The measurement was taken in July 1913 at Furnace Creek – the location for a visitor centre and a basic campground – and it came in at 57°C (134°F). This was a particular scorcher, but it's still not uncommon for temperatures to climb up to 49°C (120°F) in the shade. The park's Badwater Basin is also the lowest point in North America, stretching out at 282 feet (86m) below sea level.
The USA is awash with weird and wonderful roadside attractions from hulking animal effigies to giant food stuffs, and this one is probably the largest monster sculpture in America.

He has burst from the track’s Victory Plaza since 2008 and is the speedway's official mascot.

St Augustine is a city with a whole lot of history and its crowning jewel is Castillo de San Marcos. This is the oldest masonry fort in the United States, constructed by the Spanish from 1672 to 1695. It's a hulking structure, with walls that thrust to 33 feet (10m) and over the centuries it survived several attacks by the British. Now it's protected as the Castillo de San Marcos National Monument, which is open for self-guided walking tours.

Yes, you read that correctly: the world's largest ball of paint has become a well-loved roadside attraction in Alexandria.

This giant roadside attraction in Idaho is as cute as they come.

And at 30-feet tall (9m), it's tipped as the world's largest beagle too.
Precious little of the tallgrass prairie that once covered huge portions of North America remains, as most of it has been gobbled up and turned into farmland. That makes the great swathe of it in Kansas's Tallgrass Prairie National Preserve all the more precious. As it stands, it's the largest expanse of intact tallgrass prairie remaining in America. It serves as a habitat for species from bison and deer to the greater prairie-chicken, plus around 500 species of plant.

Best of all, the complex is growing: a further eight miles (13km) were mapped by explorers in 2021.
Guinness World Records recognises Louisiana's Lake Pontchartrain Causeway as the longest continuous bridge over water on the planet.
