Twin Falls  is the largest city in South Central Idaho as well as the seventh-largest city in the state. The youngest of Idaho's major cities at barely 100 years old, Twin Falls has become a regional cultural and economic center for both South Central Idaho and northeastern Nevada.
Once in the heart of a stretch on the Oregon Trail best known for its inhospitable environment, Twin Falls was founded in 1904 as a planned community after irrigation projects on the Snake River made large-scale agriculture in the area practical for the first time. Twin Falls is the principal city of the Magic Valley region of Idaho, so named because said irrigation projects "magically" transformed the harsh landscape into productive farmland. While agriculture remains one of the city's primary industries, its proximity to outdoor activities as well as to casino gaming in nearby Nevada give it a regional tourist flair. Twin Falls is home to over 40,000 residents, making it one of Idaho's principal cities outside the Boise metro area.
Although English is the undoubtedly the primary language in Twin Falls, a significant Hispanic community as well as refugees brought in by the local community college give the city an added multicultural element. It is not at all unusual to hear Spanish, Bosnian and Russian - among other languages - spoken in the city. That said, don't expect too much linguistic diversity; as in the rest of Idaho, English is still by far your best bet with Spanish a distant second.
Although Twin Falls is served by an extremely modest mass transit system, having your own car is effectively a requirement to see anything more than walking distance from your hotel. Cars can be rented at Magic Valley Regional Airport from many companies including Alamo, Avis, Budget, Hertz and National.
Rudimentary taxi service is available in the city if needed, but it's no Manhattan. Don't expect to hail a cab even on busy streets. You'll most likely have to call a service to get a ride, even if at the airport. Check the Yellow Pages.
Most other diversions in the Twin Falls area revolve around outdoor activities such as camping, hunting and fishing. Other activities include:
Twin Falls isn't exactly a destination for foodies. Apart from the expected assortment of chain restaurants (i.e. Chili's, Outback, the usual compliment of fast-food joints, et al.) the fare is a bit lacking. That said, Twin Falls does feature several Thai restaurants and family-oriented establishments.
Mexican cuisine is your best bet in the city. Try Garibaldi's, 645 Filer Ave., Phone: (208) 736-7408; or La Fiesta, 1288 Blue Lakes Blvd N., Phone: (208) 734-0685.
Approximately 45 minutes away in Hagerman, the Snake River Grill comes highly recommended by the locals, who often say it's worth the drive. Be sure to try the alligator. Phone: (208) 837-6227
Bars in Twin Falls close at 1 AM sharp, no excuses. Liquor by the drink on Sundays is a relatively recent innovation as well.
Twin Falls has experienced something of a hotel building boom. Many of the hotels along Blue Lakes Boulevard and Poleline Road were constructed after 2007, so there are plenty of new and comfortable rooms to choose from.
As in the rest of Idaho, the 208 area code is used in Twin Falls. Cell phone service is consistent and reliable in Twin Falls proper as well as in the surrounding communities. However, if you travel further south than Jackpot, Nevada, on US Highway 93, expect to have an intermittent signal at best until you approach Elko or Ely.
Twin Falls street addresses use the ZIP postal code 83301. Post office boxes use 83303. Most of the surrounding communities have their own ZIP codes as well.
Public WiFi access is available at most larger hotels, as well as at some coffee shops.
Given that much of the city's commercial and tourist infrastructure is concentrated around the intersection of Blue Lakes Boulevard and Poleline Road, as well as the fact nearby Perrine Bridge is effectively the only way in and out of Twin Falls from the north, traffic in the immediate area can be as heavy as anywhere in a much larger population center such as Boise. Stay alert if driving or walking through here.
