Twin Falls is the county seat and largest city of Twin Falls County, Idaho, United States. The city had a population of 44,125 as of the 2010 census. In the Magic Valley region, Twin Falls is the largest city in a one-hundred-mile (160 km) radius, and is the regional commercial center for south-central Idaho and northeastern Nevada. It is the principal city of the Twin Falls Metropolitan Statistical Area, which officially includes the entirety of Twin Falls and Jerome counties. The border town resort community of Jackpot, Nevada, fifty miles (80 km) south at the state line, is unofficially considered part of the greater Twin Falls area. Located on a broad plain at the south rim of the Snake River Canyon, Twin Falls is where daredevil Evel Knievel attempted to jump across the canyon in 1974 on a steam-powered rocket. The jump site is northeast of central Twin Falls, midway between Shoshone Falls and the Perrine Bridge.


Excavations at Wilson Butte Cave near Twin Falls in 1959 revealed evidence of human activity, including arrowheads, that rank among the oldest dated artifacts in North America. Later Native American tribes predominant in the area included the Northern Shoshone and Bannock.

The first people of European ancestry to visit the Twin Falls area are believed to be members of a group led by American Wilson Price Hunt, which attempted to blaze an all-water trail westward from St. Louis, Missouri, to Astoria, Oregon, in 1811 and 1812. Hunt's expedition met with disaster: much of his expedition was destroyed and one man was killed in rapids on the Snake River known as Caldron Linn near present-day Murtaugh. Hunt and the surviving members of his expedition completed the journey to Astoria by land.

In 1812 and 1813, Robert Stuart successfully led an overland expedition eastward from Astoria to St. Louis, which passed through the Twin Falls area. Stuart's route formed the basis of what became the Oregon Trail. Some 150 years later, Robert Stuart Middle School in Twin Falls was named in his honor.

The first permanent settlement in the area was a stage stop established in 1864 at Rock Creek near the present-day townsite. By 1890 there were a handful of successful agricultural operations in the Snake River Canyon, but the lack of infrastructure and the canyon's geography made irrigating the dry surrounding area improbable at best.

To address this issue, in 1900 I. B. Perrine founded the Twin Falls Land and Water Company, largely to build an irrigation canal system for the area. After an August 1900 area survey of 244,025 acres (98,753 hectares), in October 1900 the company was granted the necessary water rights to begin construction of the irrigation system. Several lots in the surveyed area were set aside specifically for future townsites. These lots eventually became the settlements of Twin Falls, Kimberly, Buhl, Filer, Hansen and Murtaugh. In 1902 the project nearly failed as most of the original investors pulled out, with only Salt Lake businessman Stanley Milner maintaining a stake in the company.

By 1903 Perrine, who had been a successful farmer and rancher in the Snake River Canyon, had obtained private financing from Milner and others under the provisions of the Carey Act of 1894 to build a dam on the Snake River near Caldron Linn. Completed in 1905, Milner Dam and its accompanying canals made commercial irrigation outside the Snake River Canyon practical for the first time. As a result, Perrine is generally credited as the founder of Twin Falls.

A land drawing was held for the future townsite in July 1903 with disappointing results. A much more successful drawing was held in October 1904. Twin Falls city was founded in 1904 as a planned community, designed by celebrated Franco-American architect Emmanuel Louis Masqueray, with proceeds from sales of townsite lots going toward construction of irrigation canals. Twin Falls was incorporated as a village on April 12, 1905. The city is named for a nearby waterfall on the Snake River of the same name. In 1907 Twin Falls became the seat of the newly formed Twin Falls County.

The original townsite follows a unique design. It is laid out on northeast-to-southwest and northwest-to-southeast roads. The northwest-to-southeast roads were numbered and called avenues, while the northeast-to-southwest roads were numbered and called streets. Only two central streets, the northwest-to-southeast Main Avenue and the northeast-to-southwest Shoshone Street, were named. It is purported that the reason this was done was to allow sun to come into every room in the home at some point during the day. This system created situations where one side of a street may have an entirely different address than the other, and where the corner of "3rd and 3rd," for example, was in more than one location. In 2003 the numbered northeast-to-southwest streets were renamed to alleviate decades of confusion. Later city roads, such as Blue Lakes Boulevard, Addison Avenue and Washington Street, are laid out in standard north–south and east–west orientations. Addison Avenue is named after Addison T. Smith, an early 20th Century United States Congressman from Twin Falls.

After Milner Dam was constructed agricultural production in south-central Idaho increased substantially. In 1909 the privately owned Twin Falls Land and Water Company was reorganized as the shareholder-owned Twin Falls Canal Company. Twin Falls became a major regional economic center serving the agriculture industry, a role which it has sustained to the present day. The city became a processing center for several agricultural commodities, notably beans and sugar beets. In later years other food processing operations augmented the local economy. By 1960, Twin Falls had become one of Idaho's largest cities even though its origins were still within living memory for many.

Twin Falls became the center of national attention in September 1974 when daredevil Evel Knievel attempted to jump the Snake River Canyon in a specially modified rocket cycle. Watched by millions on closed-circuit television on a Sunday afternoon, the attempt ultimately failed due to high winds and a premature deployment of Knievel's parachute. The launch ramp's foundation lies on private land on the canyon's south rim. Less than two miles west (3 km) of Shoshone Falls, it is still visible (42°35′49″N 114°25′23″W / 42.597°N 114.423°W / 42.597; -114.423).

During the last quarter of the 20th century, gradual diversification of the agriculture-based economy allowed the city to continue to grow. Major Twin Falls employers in 2006 included computer maker Dell, Inc., Glanbia, and Jayco, a recreational vehicle manufacturer. In September 2009 Dell announced it would close its Twin Falls facility by January 2010. Later in 2010 the call center company C3 opened a facility in the former Dell location. In 2012 Chobani, one of the U.S.'s largest Greek yogurt manufacturers, opened its largest factory and distribution center in Twin Falls.

In recent years Twin Falls has become quite multicultural. Thanks in large part to a refugee center operated by the College of Southern Idaho, since 1995 significant numbers of people from Bosnia and Herzegovina and the former Soviet Union have settled in Twin Falls. The city also has a sizable Hispanic population.


Twin Falls is the largest city in Idaho that is not directly on the Interstate Highway System; it is served by several major highways, including U.S. Route 30 and U.S. Route 93. Access to nearby Interstate 84 is across the canyon via the Perrine Bridge (U.S. 93); the junction is approximately five miles (8 km) north, in Jerome County. State Highway 74 provides direct access from downtown Twin Falls to southbound locations on U.S. 93, including Hollister and Rogerson, then crosses into Nevada at Jackpot and continues to a junction with Interstate 80 at Wells.

Trans IV, a small public transportation system operated by the College of Southern Idaho, is also available.

Limited commercial air service is provided at Magic Valley Regional Airport, also known as Joslin Field. As of August 2017, daily flights to Salt Lake City are available from Delta Connection (fulfilled by SkyWest Airlines) using the Canadair CRJ200. Twice-weekly service to Las Vegas was previously operated by Allegiant Air, but the airline discontinued the route in January 2012, citing insufficient ticket prices.


Twin Falls is located at 42°34'N 114°28'W (42.561,-114.464).

According to the United States Census Bureau, the city has a total area of 18.16 square miles (47.03 km2), of which, 18.10 square miles (46.88 km2) is land and 0.06 square miles (0.16 km2) is water.

The Snake River Canyon forms the city's northern limits, separating it from Jerome County. There are three waterfalls in the immediate area. Shoshone Falls is located approximately 5 miles (8.0 kilometres) east of Twin Falls city. Pillar Falls is located approximately 1 12 mi (2 12 km) upstream from the Perrine Bridge while Twin Falls, the city's namesake, is located upstream of Shoshone Falls.

Shoshone Falls stands at 213 ft (65 m), which is 46 feet (14 m) higher than Niagara Falls.

The Perrine Bridge, which spans the Snake River Canyon immediately north of the city, is one of only a handful of artificial structures worldwide where BASE jumping is legal. In September 2005 Miles Daisher of Twin Falls set a BASE jumping world record by jumping off Perrine Bridge 57 times in a 24-hour period. In July 2006 Dan Schilling jumped off the bridge 201 times in 21 hours to raise money for charity. Unlike Daisher, Schilling was hoisted to the top of the bridge by a crane after every jump.
