How Twin Falls earned the score

A city conjured from desert

Most towns grow slowly, around a harbor or a crossroads or a mill. Twin Falls did not have that luxury. In April 1904 a surveyor named John E. Hayes planted a small white flag in the middle of an ocean of sagebrush, looked through his transit at what is now the corner of Main and Shoshone, and started laying out streets for a city that had no people, no water, and no reason to exist except for one audacious idea: that you could move a river and make a desert bloom.

The idea was legal as much as it was engineering. The federal Carey Act of 1894 let private money build the irrigation that the arid West could not pay for itself, and it found its greatest expression here. By one widely cited estimate, roughly 60 percent of all Carey Act land ever irrigated in the United States ended up in Idaho, much of it fanning out from this one valley. The town was officially founded in 1904 and incorporated as a village in April 1905, the same year the water arrived.

A waterfall worth building a town around

What made the gamble worth taking was already roaring three miles to the northeast. Shoshone Falls plunges 212 feet, a full 45 feet higher than Niagara, over a rim measured at 925 feet wide, according to the record for the falls. A Salt Lake City newspaper called it a wonder “for savage scenery and power sublime” as far back as 1866, and the nickname stuck: the Niagara of the West. The Snake River had spent ten thousand years carving the canyon that would become the town’s signature, and Twin Falls simply set up shop on the rim above it.

Turn scenery into a destination

Here is the quiet problem with a knockout natural setting: it can become wallpaper. For decades the canyon and the falls were a scenic pull-off on the way to somewhere else, a quick photo on the drive between Boise and the Tetons. The water at Shoshone Falls is also seasonal. It is at its thunderous best from late March into early May, when winter snowmelt can push flows past 20,000 cubic feet per second, and a thin trickle by late summer when the irrigation that built the town diverts the river upstream. A town cannot run an economy on six good weeks of waterfall.

So the task that defines modern Twin Falls is conversion. Not “how do we get people to drive past something beautiful,” but “how do we get them to park, stay the night, eat dinner downtown, and come back.” That meant building a tourism identity that works in August as well as April, that gives a visitor more than one reason to exit the interstate, and that turns a county of dairy farms and a famous canyon into a place with its own gravity.

The canyon does the marketing

The bridge that became a launch pad

The Perrine Bridge carries U.S. Highway 93 across the Snake River Canyon on a deck that stands 486 feet above the water and runs 1,500 feet across, by the figures in its record. That height made it something almost no other structure in the country is: a place you can legally, openly BASE jump from. It may be the only man-made structure in the United States where BASE jumping is allowed year round without a permit, which has quietly turned Twin Falls into a pilgrimage site for the global BASE community. On a clear morning you can stand on the rim with a coffee and watch people step off the railing and parachute into the canyon, and nobody stops them. It is free advertising of the most heart-stopping kind.

A daredevil legend baked into the landscape

The canyon’s reputation for spectacle did not start with parachutes. On September 8, 1974, Evel Knievel tried to rocket across the Snake River Canyon just east of town in a steam-powered contraption called the Skycycle X-2. About 15,000 spectators paid 25 dollars each to watch in person, with many thousands more on closed-circuit television, according to accounts of the jump. His parachute deployed early and he drifted to the canyon floor, but the legend was set, and the dirt launch ramp is still visible from the rim. In 2016, stuntman Eddie Braun finished the job Knievel started, successfully flying a rocket across the same canyon. Twin Falls did not invent this stuff to sell tickets. It simply happened here, and the town has learned to honor it.

Building a downtown to match the scenery

The harder, slower work has been the city itself. Tourism is now Twin Falls’ fifth-largest industry, and the strategy has been to give the canyon a town worth lingering in: a revived downtown with a summer concert series, an expanding food scene, and the Canyon Rim Trail stitching the overlooks, the falls, and the bridge into one walkable edge. The College of Southern Idaho, founded in 1965, anchors the community with arts and events that keep the lights on between waterfall seasons, per its record. And the agricultural muscle underneath it all matters too. When Chobani chose Twin Falls in 2012 for what became the world’s largest yogurt plant, it added jobs and confidence that helped fund the kind of amenities tourists actually notice.

The Magic Valley’s front door

The numbers tell the story of a region that has turned scenery into spending. South Central Idaho, the tourism region anchored by Twin Falls, recorded 345.9 million dollars in direct travel spending in 2024, according to the state’s Dean Runyan report. Statewide, travelers spent 4.3 billion dollars in a recent year, per the Idaho Commerce report, and Twin Falls is increasingly where that money first lands when visitors come for the canyon country.

Shoshone Falls Park alone draws on the order of a quarter million to 300,000 vehicles a year, by the estimate in its record, each paying a modest entry fee that funds the park. The city itself has grown to roughly 55,600 people as of the 2024 estimate, up from 51,807 at the 2020 census, according to the Census Bureau, one of the fastest-growing small cities in the Mountain West. The waterfall that justified the town in 1904 is now one attraction among several, and the canyon that was an obstacle to the early engineers has become the single best thing the city has to sell.

The overnight opportunity

A Visitor Impact Score of 70 places Twin Falls firmly On the Map. This is a town with a genuinely ownable identity, not borrowed scenery but a story it authored: people drew a city in the dirt, moved a river to feed it, and ended up guardians of a canyon the rest of the country comes to jump off of. Few places this size can claim a waterfall taller than Niagara, the country’s most accessible BASE-jumping bridge, and a bona fide Evel Knievel legend, all within a few miles of one downtown.

The clearest opportunity, and the honest gap behind the score, is conversion from day trip to overnight stay. The falls are seasonal, much of the canyon traffic is built around a fee-station drive-up and a photo, and a meaningful share of visitors still treat Twin Falls as a stop rather than a stay. The upside is enormous and very reachable: a stronger lodging and evening offer, a reason to be downtown after the falls close, and year-round programming that does not depend on snowmelt would turn a quarter million windshield visits into hotel nights, dinners, and repeat trips. The canyon already does the marketing. The work now is keeping people in town once it has hooked them.
