10 Flattest States in America

By Louise Peterson · Last updated on February 6, 2025

Think America’s all about majestic mountains and rolling hills? Think again. Some states are so flat you could watch your dog run away for three days. While elevation changes might not sound exciting, these pancake-like places have their own unique charm and challenges.

Here you can find endless horizons and some remarkable ecosystems because America’s flattest states prove you don’t need mountains to be interesting. Let’s explore these level landscapes where a speed bump might qualify as the highest point in town, and where “hiking” often means a casual stroll through cornfields.

10. Indiana

Indiana

The Hoosier State takes “level playing field” quite literally. Outside of some gentle hills in the south, Indiana’s landscape is as flat as they come. This flatness helped create America’s racing culture – just try finding a better place to build the Indianapolis Motor Speedway.

The state’s endless horizon made it perfect for farming, though locals joke that their corn grows so tall it creates the only elevation changes they see all year. Basketball became huge here partly because you could build courts anywhere without having to grade the land. Even the state’s nickname, “The Crossroads of America,” hints at how easy it is to build highways across this prairie paradise.

9. Mississippi

Mississippi

The Magnolia State proves flat can be fascinating. Outside of the occasional bluff along the Mississippi River, this state’s as level as a pool table. The flatness created some of the world’s richest farmland in the Delta region, where cotton fields stretch to the horizon like a natural bathmat.

Local wisdom says the only hills you’ll find are ancient Native American mounds and the levees keeping the mighty Mississippi from deciding to rearrange the landscape. The lack of elevation makes for spectacular sunsets, though it also means storm watching becomes an extreme sport – there’s nothing to slow down those Gulf Coast hurricanes.

8. Iowa

Iowa

Welcome to the state where even the pigs get a view of tomorrow’s weather coming. Iowa’s prairieland is so flat that farmers joke they can see their neighbor’s business three counties over. This pancake-like topology makes it perfect for growing corn and soybeans – roughly 90% of the land is farmable.

The few “hills” are really just gentle rolls that wouldn’t challenge a toddler on a tricycle. Des Moines residents brag about the State Capitol being built on one of the state’s “high points,” though folks from Cedar Rapids might need a surveyor’s equipment to notice the elevation change.

7. Kansas

Kansas

Dorothy wasn’t kidding about seeing Toto run away for days. Kansas defines flat – so much so that scientists actually proved it’s flatter than a pancake in a published study (yes, really). The state’s level landscape made it perfect for the Santa Fe Trail and later, America’s first transcontinental highway.

Grain elevators serve as skyscrapers here, visible from miles away like prairie lighthouses. Local humor says the state’s highest mountains are the piles of snow the plows leave in parking lots. No wonder the chief’s are so good at football; they can throw their ball to the next state without much hassle!

6. Delaware

Delaware

The First State might be small, but it’s also seriously smooth. The highest natural point, Ebright Azimuth, rises to a whopping 448 feet – basically a speed bump by mountain state standards. This flatness makes Delaware perfect for chicken farms and credit card companies (apparently, both appreciate level ground).

Beach lovers benefit too – the whole coastline stays nice and flat, perfect for those long boardwalk strolls. This tiny state has the lowest mean elevation in all of the nations, a staggering 60 feet.

5. Minnesota

Minnesota

The Land of 10,000 Lakes proves that flat doesn’t mean boring. Glaciers basically ironed this place out eons ago, leaving behind a landscape perfect for farming and ice hockey rinks. The northern part does have some hills (Minnesotans call them “mountains” with a straight face), but most of the state’s flatter than a frozen lake in January.

This level landscape helped create the nation’s largest mall – where else could you build something that massive without major excavation? The flatness also explains why Minnesotans get so excited about their ski “slopes” – when every speed bump qualifies as a black diamond run.

4. Louisiana

Louisiana

The Bayou State takes flat to new depths – literally. Much of Louisiana sits below sea level, much like the Netherlands. The landscape’s so flat that New Orleans uses levees to keep the Mississippi River from deciding to take a new route to the Gulf.

This ultra-flat topology created the perfect environment for swamps, crawfish farms, and Mardi Gras parades that can be seen from miles away. Local kids think mountain climbing means going up to the second floor of their homes, while the highest natural point barely tops 500 feet.

3. North Dakota

North Dakota

Peace Garden State? More like Prairie Plate State. North Dakota‘s landscape is so flat you can almost see the curvature of the Earth (or your cousin’s house in South Dakota). The state is famous for its endless wheat fields which is a stunner in its own right.

Theodore Roosevelt came here for the badlands but stayed for the horizon-stretching views. The flatness makes winter winds so fierce that locals don’t measure snow in inches but in which direction it’s currently blowing. Even the state’s famous sunflowers grow extra tall, probably just trying to add some vertical interest to the landscape.

2. Illinois

Illinois

The Prairie State earns its nickname honestly – outside of a few “mountains” in the south (which Coloradans would call speed bumps), Illinois is flatter than a deepdish pizza. This levelness helped make it America’s breadbasket and Chicago’s foundation.

Speaking of Chicago, its skyscrapers stand out so dramatically because nature provided zero competition in the vertical department. The state’s highest natural point rises to a modest 1,235 feet, which locals treat with the same reverence mountaineers reserve for Everest. Farm kids grow up thinking clouds are the only natural things that rise above the horizon.

1. Florida

Florida

Congratulations, Sunshine State – you’re America’s flattest! Florida’s highest natural point, Britton Hill, reaches a dizzying 345 feet above sea level, making it the lowest high point of any state. This extreme flatness explains why early developers could drain swamps and build cities practically anywhere.

Disney World’s Cinderella Castle might be the tallest “mountain” many Floridians see regularly. The state’s so flat that speed bumps in parking lots require warning signs, and locals consider highway overpasses scenic overlooks. But hey, it also creates perfect beaches, amazing wetlands, and the only place where alligators can casually stroll between puddles without having to climb anything.
