Hailey, 12 miles south of Ketchum and linked by a popular rail-trail bike path, was founded originally in the 1880s as a supply center for local silver and lead mines and is now the home base of all those workers who make the resorts run smoothly and ski in between shifts. Hailey feels much more friendly and low-key than Ketchum or Sun Valley, and the eating options are much more down-to-earth. For breakfast or lunch, head to diner-style Shorty’s Diner (126 S. Main St., 208/578-1293), originally built (but no longer owned) by Die Hard actor Bruce Willis. (His ex-wife, movie star Demi Moore, is a local mom about town.)
