Observation decks present an awesome panorama of a canyon carved 15,000 years ago by the great Bonneville Flood. Palisades rise as high as 600 feet above two golf courses and a city park that occupy the canyon floor. In 1974, Evel Knievel tried to rocket across the Snake River Canyon on a motorcycle, a couple of miles upstream from Perrine Bridge. The Montana stuntman couldn't make it across and parachuted to the canyon floor. A little farther upstream, on Shoshone Falls Road, is Shoshone Falls, known as The Niagara of the West.
Spring is the best time to visit, when the Snake River is swollen from snowmelt.
Audience members lay back and look upward at the dome and are totally surrounded by subject matter. Shows in the 154-seat theater have included Through the Eyes of the Hubble Telescope and Innerspace , which explores the human body. The Great Casino Escape for Boise is Jackpot, Nevada , about 60 miles south of Twin Falls, or about 190 miles, and three to 3 hours by car, from Boise. Take Interstate 84 east to the Twin Falls, U.S. Highway 93 exit, and drive south on U.S. 93 to Jackpot, just over the Nevada border. Dinner and cocktail stage presentations are offered Tuesday through Sunday and feature people and groups that were big in the past, such as Chubby Checker, Lacy J. Dalton and The Coasters.
