Opening in summer 2026, The Observatory Sun Valley, A Viceroy Resort rises at the gateway entrance to downtown Ketchum, Idaho — the historic, walkable heart of North America's first all-season mountain resort destination. Named in homage to the storied Observatory that once anchored this corner of Sun Valley, the property draws on the legacy of W. Averill Harriman, who founded the resort in 1936 and made it the playground of artists, writers, and luminaries. The resort's 73 guest rooms and 12 single-level penthouse residences all offer sweeping views of Bald Mountain and the surrounding Wood River Valley wilderness. Its modern architecture blends clean contemporary lines with materials and proportions that recall classic European ski lodges, while interior spaces employ natural finishes reflecting the region's distinctive aesthetic. The defining feature is a state-of-the-art rooftop observatory equipped with an active telescope, positioned to harness the Central Idaho Dark Sky Reserve — one of only 12 such reserves in the world. Year-round programming takes guests from spring fly-fishing and summer mountain hiking to world-class downhill skiing in winter, all just steps from the property.
