Perched in the heart of Sun Valley, Idaho — America's first purpose-built ski resort — The Observatory channels the region's rich astronomical heritage. Sun Valley sits at over 5,900 feet elevation, offering some of the clearest skies in the American West, making stargazing an experience unto itself. The Viceroy's signature design blends rugged mountain elegance with refined contemporary style, surrounded by the stunning Sawtooth Range. With world-class skiing on Bald Mountain right at your doorstep and Ernest Hemingway's favorite retreat just down the road, history and adventure collide here in spectacular fashion.
Sun Valley's iconic Dollar Mountain is perfect for beginners and families, while Bald Mountain satisfies even the most seasoned skiers. Off the slopes, visit the Sun Valley Pavilion — a legendary outdoor venue where Sonja Henie and other icons once performed — or explore the charming Ketchum village for local dining and galleries. And of course, pay homage to Hemingway, who called this valley home and is buried just steps away in Ketchum.
