The Observatory, A Viceroy Resort, has opened in Sun Valley, Idaho, boasting its own rooftop observatory and an on-site spa coming soon.
Situated in the heart of downtown Ketchum, The Observatory reimagines the traditional mountain escape with a distinctly modern approach to luxury. The intimate 73-room resort features 12 residences, culinary and cocktail experiences, a 465 square metre spa opening later this season, a rooftop observatory with a state-of-the-art telescope and a collection of experiences designed to immerse guests in the spirit of Sun Valley.
Drawing from Sun Valley’s alpine landscapes, Austrian-inspired heritage and storied spirit of exploration, The Observatory offers a modern interpretation of the mountain retreat. The resort’s design brings a sophisticated residential sensibility to the rugged beauty of the American West, creating an atmosphere that is at once intimate, welcoming and connected to its surroundings.
Led by De Reus Architects alongside FDG Design Group, the interior architecture and design celebrate the natural materials, textures and colours of the Wood River Valley. Montana Moss Rock sourced from Idaho and Montana defines the exterior, while richly textured woods harvested throughout the Pacific Northwest, warm taupe tones, slate finishes and luminous copper accents create inviting interiors that feel both timeless and contemporary. Traditional Shou Sugi Ban woodwork lends depth to select spaces, complemented by bespoke furnishings, layered textiles and subtle celestial details that pay homage to the resort’s extraordinary setting.
The resort’s 73 guestrooms and suites offer an intimate sanctuary, pairing the comforts of a luxury residence with sophisticated design and thoughtful amenities. Rich textures, ambient lighting, granite finishes and carefully considered details create a welcoming retreat that reflects the surrounding landscape while delivering an elevated experience.
At the heart of the resort is its namesake rooftop observatory. Located within the Central Idaho Dark Sky Reserve, the nation’s first Gold Tier reserve spanning more than 1,400 square miles, The Observatory invites guests to discover the celestial wonders that illuminate one of North America’s most extraordinary night skies.
Crowning the resort, a 12-foot, 6-inch Ash Dome houses a sophisticated PlaneWave CDK17 telescope, transforming the rooftop into an intimate gateway to the cosmos.
Bringing an exciting new energy to Ketchum’s dining scene, The Observatory introduces a collection of distinctive culinary concepts celebrating the flavours and traditions of the Mountain West. The resort’s offerings include Joan, the signature restaurant showcasing elevated contemporary American cuisine; Jerry’s Bar, a lively destination for cocktails and après-ski; Odin’s Corner, an inviting all-day café; and Andy’s Watershed, a relaxed poolside retreat for signature cocktails and elevated bites. Together, these venues create a vibrant new gathering place for hotel guests and the local community alike.
Opening later this season, The Spa at The Observatory will introduce a sophisticated new wellness destination to Sun Valley. Spanning 465 square metres, the mountain-inspired sanctuary will feature a thermal pool, sauna and hot and cold therapies.
The Observatory is also home to 12 single-level penthouse residences that combine the privacy and sophistication of a luxury home with the amenities and services of a resort. Ranging from approximately 139 to 325 square metres, the two- to four-bedroom residences feature appointed living spaces, full kitchens, fireplaces and private outdoor areas. Select residences offer flexible hotel lock-off configurations, while owners enjoy access to the resort’s dining, wellness, concierge services and distinctive experiences, creating a seamless connection between residential living and the energy of The Observatory.
With more than 418 square metres of versatile event space, The Observatory offers a sophisticated setting for executive retreats, milestone celebrations and private gatherings.
From the expansive Durrance Ballroom to the rooftop observatory, the resort offers opportunities for gatherings that extend well beyond traditional meeting spaces.
“The Observatory reflects Viceroy’s approach to creating hotels that are distinctive, immersive and thoughtfully tailored to how today’s travellers want to experience a destination,” said Arash Azarbarzin, CEO of Viceroy Hotels & Resorts.
“With its design, culinary offerings, wellness experiences and one-of-a-kind rooftop observatory, the resort brings together thoughtful hospitality and memorable experiences in a way that feels elevated, engaging and entirely its own.”
