Plan a trip to Sun Valley

The brainchild of the chairman of Union Pacific Railroad who wanted to create a destination ski resort to increase ridership, Sun Valley encompasses the Sun Valley ski resort and the nearby town of Ketchum. The 1932 Winter Olympics and celebrity promotions helped make Sun Valley a popular destination for athletes and travelers alike (including Clark Gable and Ernest Hemingway.) Hike the rugged trails and take in the breathtaking views of Sawtooth National Recreation Area in spring, summer, and autumn. After a satisfying day of good walking, treat yourself to a dip in one of the 13 soothing hot springs of Sun Valley - bring drinking water and a towel with you. Drop by the Sun Valley Center for the Arts for a lecture by a famous author, a class on color, or a play performed by the Center's own Company of Fools.
