Nebraska, worth the detour.

Buffalo Bill Cody's 1886 Second Empire mansion and giant barn, the working headquarters of his 4,000-acre ranch between Wild West Show tours -- the show that took the myth of the frontier to Europe and back. Original outbuildings still stand on the 25-acre core.

Two towering badland formations that pioneers wrote home about decades before Chimney Rock had its own postcard -- early travelers called Courthouse Rock the 'Castle' or 'Solitary Tower' and often detoured miles just to see it up close. A quiet, uncrowded overlook pull-off compared to its more famous cousin up the trail.

A former Army theater turned natural history museum, anchored by two Columbian mammoth bulls whose tusks locked in mortal combat and were found fossilized together, still fused, 10,000 years later. Fort Robinson itself is where Crazy Horse was killed in 1877 and where WWII German POWs later trained war dogs -- a fort with two irreconcilable American stories under one roof.

Ground zero for the 1862 Homestead Act -- the law that gave away 270 million acres and reshaped the entire American West. Daniel Freeman filed one of the first claims here minutes after the act took effect. The plow-shaped Heritage Center sits on his original quarter-section, with restored tallgrass prairie you can walk through.

The 'Tower on the Plains' -- a 400-foot Art Deco skyscraper-capitol topped by 'The Sower,' rising alone over the prairie. Free tours depart the North Entrance on the second floor; climbing to the observation deck gives a genuine capital-city check-in and a rooftop view over Lincoln unlike any other statehouse in the country.

The visitor center and Oregon Trail Museum sit at the base of the bluff -- a different check-in than the existing Saddle Rock summit hike. Wagon ruts are still visible nearby, and the museum holds William Henry Jackson's pioneer-era paintings of the trail landmark that told westbound travelers they'd made it a third of the way to Oregon.

Harold Warp grew up in a sod house near Minden, made a fortune manufacturing Flex-O-Glass plastic film, and then spent decades obsessively collecting one example of nearly every invention that changed daily American life -- 50,000 items across 28 buildings, from antique tractors and a steam carousel to 17 historic flying machines, arranged in strict chronological order so visitors literally walk through the evolution of the washing machine, the lawn mower, and the automobile in one place. Called 'the Smithsonian of the Plains.'

Grew out of the small Riverview Park Zoo of 1894 into a world-class complex famous for engineering superlatives: the Lied Jungle (one of the world's largest indoor rainforests), the Desert Dome (world's largest indoor desert and largest glazed geodesic dome), and Kingdoms of the Night (world's largest nocturnal exhibit). In August 2014 TripAdvisor's algorithmic ranking of millions of reviews across 275 major zoos named it the world's best zoo, ahead of San Diego Zoo and Loro Parque -- a striking claim to fame for a mid-size Nebraska city and a natural family-anchor check-in for an Omaha stop.

A 300-foot museum literally built as a bridge over I-80 itself (accessible via exits 275/272), opened in 2000 to turn the ultimate drive-through complaint -- monotonous interstate miles -- into the destination. Inside, the exhibit walks visitors from Fort Kearny and the 1848 convergence of the Oregon, California, and Mormon Trails through the Pony Express, transcontinental railroad, Lincoln Highway, and modern I-80, letting travelers literally stand above the highway they just drove and see its 170-year backstory underneath their tires.

Housed inside Omaha's restored 1931 Art Deco Union Station, the museum keeps the building's original grand waiting room, ticket windows, and a life-size train exhibit intact, so visitors are walking through a functioning piece of the golden age of rail travel rather than a purpose-built museum shell -- a rare case where the building itself is the primary artifact.

In 1971 paleontologist Mike Voorhies spotted a rain-eroded skull of a baby rhinoceros poking out of a thick ash layer in a north-central Nebraska pasture -- the first clue to a Miocene-era 'waterhole of death' where an ashfall from a volcano 900 miles away in modern Idaho (1,000 times the size of the 1980 Mount St. Helens eruption) buried and preserved over 200 complete animal skeletons in place. Twenty years of excavation later, the Rhino Barn now lets visitors watch real fossils emerge from the ground exactly where they fell 12 million years ago.

Originally housed at nearby Offutt Air Force Base -- headquarters of the actual Strategic Air Command during the Cold War -- the museum relocated to its current I-80 site in 1998 and now displays Cold War-era aircraft including an SR-71 Blackbird, the Mach-3+ spy plane built by Lockheed's Skunk Works under Kelly Johnson. Walking beneath a real Blackbird just off the interstate turns an anonymous stretch of I-80 southwest of Omaha into a stop with genuine nuclear-era stakes attached.

At the Norden Bridge, the whole Niobrara River funnels over a bedrock ledge into a boiling hydraulic chute strong enough to trap kayaks -- canoeists are required to portage around it. A short walk from the Nature Conservancy's Niobrara Valley Preserve trailhead puts you right above the churn.

Nebraska's highest ground isn't a mountain -- it's a barely-there rise on a working bison ranch, 5,429 feet up, a mile from where Nebraska, Wyoming, and Colorado all meet in one spot. Leave three bucks in the honor box at the gate and you can stand on top of the entire state.

A Nebraska farm boy named Ole Herstedt spent 35 years chasing big game on every continent, then hauled the trophies home to a tiny Sandhills-edge steakhouse just off I-80 -- polar bear, Cape buffalo, and an actual lion all watching you eat your ribeye. It is the reason people say I-80 through Nebraska isn't boring if you know where to get off.

Nebraska's largest waterfall by volume drops off a rimrock ledge into the Snake River canyon just three miles from Merritt Reservoir -- on private ranchland, so the owners built a viewing trail and a one-dollar honor-box gate instead of fencing it off.

In 1975, small-town furniture-store owner Harold Davisson buried a 45-ton concrete vault stuffed with a Chevy Vega, bikini bottoms, and 5,000 other relics of the Bicentennial -- then sealed it for exactly 50 years. It was cracked open again on July 4, 2025, and the town built a whole festival around the reveal.
