Begins at Interstate 84 near Bliss and follows U.S. 30 southeast through Twin Falls to Idaho 50, then north on Idaho 50 to I-84. Also U.S. 93 from Twin Falls north to I-84.

South Central geography is the result of huge prehistoric cataclysmic forces making the breathtaking Snake River Canyon. The byway provides a glimpse into this remarkable geology, history and a nostalgic rural lifestyle. Beginning at Bliss, the byway drops into the canyon providing a grand entrance, and visitors discover country towns, historic place, fish hatcheries, wildlife habitats, and recreational opportunities.

South of Hagerman, Thousand Springs is clearly visible from the byway. This pure, clean oxygenated water maintains a constant temperature of 58 degrees Fahrenheit, ideal conditions for growing trout. The hatcheries located along the 30-mile stretch of the Snake Rover in the Hagerman Valley raise 70 percent of the trout produced in the United States. Boat tours and dinner cruises available in the area allow visitors to get up-close and personal with some of the Thousand Springs along this stretch of the Snake River.

Travel on and enjoy small town delights and festivals such as the Trout Festival in Buhl and Idaho's largest county fair in Filer, both in September. In Twin Falls visit Historic Downtown Twin Falls; home to unique shops and galleries. The City Park is the site of the historic band shell and home of one of the country's longest playing city bands. Take a side trip to the 212-foot Shoshone Falls. The best viewing is in the early spring of high run-off years before the water is put to work irrigating the area's fertile farmland. The Centennial Trail, starting at Shoshone Falls Parl, will take you to the Evel Knievel jump site, and provide a panoramic view of the area.

In the fall, travel to the South Hills via Hansen and Kimberly for spectacular fall foliage and trails for cycling, horseback riding and hiking. This area is home to some of the best winter recreation in the region.


U.S. 30 and Idaho 50 are two-lane roads with some passing lanes.

When to go
