Twin Falls is the county seat and largest city of Twin Falls County, Idaho, United States.[7] The city had a population of 51,807 as of the 2020 census.[8] In the Magic Valley region, Twin Falls is the largest city in a 100-mile (160 km) radius, and is the regional commercial center for south-central Idaho and northeastern Nevada.[9] It is the principal city of the Twin Falls metropolitan statistical area, which officially includes the entirety of Twin Falls and Jerome Counties.[10] The border town resort community of Jackpot, Nevada, 50 mi (80 km) south at the state line, is unofficially considered part of the greater Twin Falls area.[11] 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.


View of Twin Falls, 1934

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.[12] Later Native American tribes predominant in the area included the Northern Shoshone and Bannock.[13]

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, who 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.[14]

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.[15] Some 150 years later, Robert Stuart Middle School in Twin Falls was named in his honor.

Snake River Canyon at Twin Falls, Idaho

The first permanent settlement in the area was a stage stop established in 1864 at Rock Creek near the present-day townsite.[16] By 1890, a handful of successful agricultural operations were 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 ha) 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 City businessman Stanley Milner maintaining a stake in the company.[17]

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.[18] As a result, Perrine is generally credited as the founder of Twin Falls.[19]

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.[17] 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.[20] 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 purported reason this was done was to allow sunlight to come into every room in the homes at some point during the day. 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. This system created situations where one side of a street may have an entirely different address from the other, and where the corner of "3rd and 3rd", for example, occurred 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 honors Addison T. Smith (1862–1956), a 10-term congressman (1913–33) from Twin Falls.[21]

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.[17] 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, though its origins were still within living memory for many.

Twin Falls became the center of national attention 50 years ago 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.[22][23][24][25] The launch ramp's foundation lies on private land on the canyon's south rim. Less than 2 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 Dell, Glanbia and Jayco. In September 2009, Dell announced it would close its Twin Falls facility by January 2010.[26] Later in 2010, the call center company C3 opened a facility in the former Dell location.[27]

In recent years, Twin Falls has become quite multicultural. Due 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 one of only three Idaho cities that has a council-manager form of government.[28] The seven-member Twin Falls city council is directly elected in nonpartisan municipal elections to four-year terms. The mayor, who holds little executive power, is periodically selected among current city council members to chair meetings, and is "considered the official representative of the city." City council meetings are usually held on Mondays.[29]

The city's day-to-day operations are overseen by a city manager, who is appointed by the city council. The city government through various citizen boards oversees parks and recreation, planning and zoning, sanitation and garbage collection, street maintenance, and wastewater collection, and maintains police and fire departments. Twin Falls Public Library, Twin Falls Municipal Golf Course and Joslin Field-Magic Valley Regional Airport are also under the city's jurisdiction.

Higher education


Twin Falls is home to the College of Southern Idaho (CSI), a large community college in the northwestern part of the city. The three state universities (Boise State University, Idaho State University, and the University of Idaho) offer classes on the CSI campus. The nursing program received money from the 2007-2008 state budget to construct a state-of-the-art nursing facility to complement the nursing program.[30] The CSI men's basketball team won its third NJCAA Division I Championship in March 2011.[31]

Primary and secondary schools


Public schools are administered by the Twin Falls School District, including Twin Falls High School, Canyon Ridge High School, the alternative Magic Valley High School, three middle schools, and nine elementary schools. Also, Twin Falls is home to Xavier Charter School and the district was awarded best title 1C district in the state.[32]

On March 14, 2006, registered voters approved a bond to build an additional high school. A citywide contest was held to determine the school's nickname. In November 2006, the Twin Falls school board selected "River Hawks", thus officially starting the Canyon Ridge High School River Hawks. Also on the bond, were plans to make general improvements to existing school facilities and to convert the junior high schools to middle schools. These projects were completed for the 2009–10 school year. The addition of Canyon Ridge High School meant that the student population was split nearly in half. Athletics for both schools are designated 4A rather than 5A by Idaho High School Activities Association[33][34]

Twin Falls, the state's seventh-largest city, is the fastest growing city in south-central Idaho.[36] As of April 2011, unemployment in Twin Falls County stood at 9.5%, below Idaho's average of 9.6%. From 1998 to 2007, the unemployment rate was steadily decreasing, to a low of just under 2%. Then, in tandem with the national economy, the unemployment rate increased to nearly 9.5% as of April 2011.[37]

Twin Falls is the home of cheese producer Glanbia Foods, a major American division of Irish food company Glanbia plc.[38]

Falls Brand, another award-winning food company, is located in the southern part of Twin Falls. In early 2011, Falls Brands' Old Fashioned Basque Chorizo sausage won the "Hold the Mustard" award presented by the National Meat Association (NMA) every year during their annual NMA Annual Gourmet Sausagefest.[39]

Another mainstay is the College of Southern Idaho (CSI). Boasting a student population of 3,433, this junior college may be an alternative for students not yet ready to attend a four-year university. Many students are from out-of-state and live in CSI's residential halls.[40]

Other large employers include Amalgamated Sugar Company, makers of White Satin sugar;[41] and Lamb Weston, which has a food-processing plant located in west Twin Falls. It employs 500 and its annual revenue is about $100 million.[42]

In spite of a troubled national economy, Twin Falls has seen rapid development since 2006. Many major retail outlets had opened stores in Twin Falls between 2006 and 2011.[43]

In November 2009, a new Walmart Supercenter opened, bringing to the region an estimated 100 additional jobs.[44] In October 2010, C3, a customer call center, opened in the former Dell facility. It was a large boost to an already busy economy, providing close to 1,000 jobs.[45] In July 2011, C3 announced it was filling another 300 C3 jobs in Twin Falls due to brisk business.[46]

Creating 40-50 new jobs, Magic Valley Cinema 13 constructed a new theater equipped with D-BOX seating. The new entertainment center was developed in association with the unprecedented growth in the Magic Valley.[47]

In response to a growing population base, Twin Falls County voters voted to construct a new hospital in the northwest section of Twin Falls to replace the city's existing hospital. In spring 2011, the new 700,000-sq-ft facility, St. Luke's Magic Valley, was opened. One of the features of the new hospital is that all 186 rooms are private with family accommodations.[48][49]

China Mountain Wind, LLC in 2011 had proposed to construct a 300,000-acre (1,200 km2) wind farm after the environmental impact is weighed. Twin Falls County was expected to generate $33.4 million in tax revenues. Local schools and services were receive a portion of the tax revenue. The construction of the wind farm was to bring to the area 400-750 full- and part-time jobs during construction and 24-46 new jobs to maintain the facility.[50]

In 2012, Twin Falls hosted the Idaho Republican Party convention, which was expected to create more positive economic activity.[51]

Chobani Yogurt Company, in 2012, opened the world's largest yogurt manufacturing plant, providing an additional 300 jobs to the Twin Falls community.[52]

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 about 5 mi (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.

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.[54] 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.[55]

When Twin Falls surpassed a population of 50,000 people, it then became federally required to provide a public transportation system for its citizens. (Read Metropolitan planning organization for more information.) On July 1, 2023, the city of Twin Falls launched a Microtransit system known as Ride TFT (Twin Falls Transit.) It was initially launched as a pilot program and was to run for two years. But in late January 2024, it was found to have quickly become a success in the community. While officials expected around 2,000 riders per month. In its first month, it had a ridership of 3,200. It had consistently gone up since then, nearly tripling initial projections during the month of December 2023.[8][20] Typical fare is $3.00 a ride in the city of Twin Falls boundary.[27] Check out RideTFT.com for more information.


Shoshone Falls along Snake River

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 0.06 square miles (0.16 km2) is covered by water.[56]

The Snake River Canyon forms the city's northern limits, separating it from Jerome County. Three waterfalls are in the immediate area. Shoshone Falls is located about 5 mi (8.0 km) east of Twin Falls city. Pillar Falls is located roughly 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 ft (14 m) higher than Niagara Falls.

View of the Perrine Bridge from the south side of the canyon

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.[57]



Twin Falls experiences a semiarid climate (Köppen climate classification BSk).

Highs reach 90 °F (32 °C) on average 22.7 days per year,[58] but very rarely exceed 100 °F (38 °C). Winter snowfall averages 24.2 inches (61.5 cm) per year,[58] though much heavier amounts have fallen. In Twin Falls proper, an average snowfall uncommonly exceeds 6 inches of snow.
