There is a specific, golden-hued nostalgia that settles over Sun Valley like a hand-stitched cashmere throw. It is the scent of pine needles and woodsmoke, the sight of a perfect, treeless peak bathed in Alpenglow, and the lingering whisper of Ernest Hemingway’s typewriter. Established in 1936 by W. Averell Harriman of the Union Pacific Railroad, Sun Valley was famously modeled after the glitzy Swiss resorts of St. Moritz and Davos. It was America’s first true destination ski resort, a place where Marilyn Monroe sought refuge and where the world’s first chairlift was born.
As we look toward the 2025-26 winter season, Sun Valley finds itself at a poignant crossroads. While it celebrates its 90th anniversary—a milestone that honors its storied past—the resort is also embracing a sophisticated future. With the introduction of seamless RFID technology and an expansive new gladed terrain, the "Old-School" charm of Sun Valley has never felt more contemporary. This is a guide for the traveler who seeks the thrill of a 3,400-foot vertical drop by day and the quiet intimacy of a fire-lit lounge by night.
The Mountain Majesty: Baldy and Beyond
To understand Sun Valley is to understand "Baldy." Bald Mountain, rising to a peak elevation of 9,150 feet, is the resort's crowning jewel. Unlike the jagged, rocky outcroppings of the Tetons, Baldy is a masterpiece of consistent pitch and sweeping, sun-drenched bowls. It offers 2,533 acres of skiable terrain that caters to a refined palate, where the lack of lift lines is as much a part of the luxury as the snow quality itself.
For the 2025 season, the conversation centers on the Sunrise expansion. This project has added 90 acres of world-class gladed terrain to the mountain’s southern flank, specifically designed for those who find their rhythm among the trees. These new glades provide a challenging, sensory experience, weaving through Douglas firs and open glens that feel worlds away from the groomed runs.
While Baldy is for the bold, Dollar Mountain serves as its gentle, sun-soaked sibling. Perfect for those refining their technique or traveling with younger family members, Dollar features "Sunny’s Adventure Park" and a progression of terrain parks that feel approachable and playful.
"Sun Valley isn't just a place to ski; it’s a place to find a rhythm. The descent from the top of Baldy is a continuous, three-mile meditation in motion." — An Insider's Whisper
For those whose hearts beat for the untamed, Sun Valley Heli Ski—the first operation of its kind in the lower 48—offers access to three separate mountain ranges. Meanwhile, the Sun Valley Nordic Center provides over 40 kilometers of meticulously groomed trails for cross-country enthusiasts, winding through the pristine Wood River Valley.
Celestial Wonders and Cultural Echoes
When the lifts stop turning, the true magic of Sun Valley begins to reveal itself. Perhaps its most underrated luxury is its darkness. Sun Valley is a key gateway to the Central Idaho Dark Sky Reserve, a staggering 1,416-square-mile protected area.
In an age where true darkness is a rare commodity, standing under the Sun Valley sky is a spiritual experience. The lack of light pollution means the Milky Way is not just visible; it is brilliant, appearing as a thick, luminous ribbon stretching across the Idaho wilderness. It is a reminder that the most luxurious experiences are often the ones provided by nature herself.
Beyond the stars, the town of Ketchum—Sun Valley’s rustic yet refined neighbor—is a hub for the arts. The Sun Valley Museum of Art and the Argyros Performing Arts Center host world-class talent year-round, ensuring that the après-ski culture is as much about intellectual stimulation as it is about social connection. For history buffs, a pilgrimage to the Hemingway Memorial or a quiet moment in Suite 206 at the Sun Valley Lodge (where he finished For Whom the Bell Tolls) is a mandatory ritual.

Where to Stay: Luxury Skiing Idaho
Accommodations in Sun Valley are divided between the historic elegance of the Sun Valley Village and the contemporary energy of downtown Ketchum.
The Legend: Sun Valley Lodge
Reimagined in 2015, the Sun Valley Lodge remains the "Grand Dame" of Idaho. The hallways are lined with black-and-white photographs of the celebrities who have graced its rooms since the 1930s. The 20,000-square-foot spa is a sanctuary of wellness, but the true highlight is the heated outdoor pool—a year-round oasis where you can soak while watching the snow fall on Baldy.
The Modern Hub: Limelight Hotel Ketchum
For those who prefer to be in the heart of the action, the Limelight Hotel is the social center of Ketchum. With its expansive lounge, live music, and airy, contemporary rooms, it offers a more "mountain-modern" alternative to the Lodge’s classicism.
