Twin Falls County, Idaho

Twin Falls County is in southern Idaho, right along the Nevada border. Shoshone Falls is the big attraction here, often called the “Niagara of the West.” Twin Falls serves as the county seat and is easily the biggest city in the area.

Much of the county is fairly flat, but the Snake River Canyon is anything but ordinary. Agriculture is a huge part of life here, with dairy farms and potato fields stretching across the landscape. Farming traditions run deep, although newer industries and technology businesses are starting to make their mark.

If you’re looking for an adrenaline rush, Perrine Bridge is famous for its base jumping. It’s one of the few places in the country where the sport is legally allowed year-round. Add in the Snake River and its dramatic canyon, and Twin Falls County has plenty of scenery and adventure packed into one corner of Idaho.
