Sun Valley's summit reaches 9,150 feet, dropping 3,399 vertical feet to a base at 5,751 feet across 121 runs spread over 2,054 acres near Ketchum, Idaho. Terrain splits 42 per cent intermediate, 36 per cent beginner, 20 per cent advanced and 2 per cent expert, with average annual snowfall of roughly 220 inches. The resort carries Ikon Pass access across its Bald Mountain and Dollar Mountain terrain. Nineteen lifts, including nine quad chairs, one six-person chair, three triple chairs and a gondola, serve the two mountains alongside two double chairs and three surface lifts.
Sun Valley holds a unique place in ski history as North America's first purpose-built destination ski resort, a status reflected in its world-class grooming and consistently low lift-line waits despite its fame. Bald Mountain carries the resort's main advanced and intermediate terrain, while the gentler Dollar Mountain serves beginners and families. The resort's Hollywood-era glamour heritage remains part of its identity alongside its modern Ikon Pass destination status.
In 1935, Union Pacific Railroad chairman Averell Harriman set out to build North America's first destination ski resort, sending Austrian ski instructor Count Felix Schaffgotsch to scout locations across the American West. Schaffgotsch chose Ketchum, a mining town surrounded by mountains, and construction began in May 1936 on the 3,200-acre former Brass Ranch. Sun Valley Lodge opened in December 1936, followed by the Swiss-style Sun Valley Inn in 1937 and The Ram restaurant in 1938.
That same 1936 season, Sun Valley became the birthplace of the modern ski lift: a railroad engineer who had built a system for loading banana bales onto cargo ships adapted the concept into the world's first chairlift, installed on Dollar Mountain. Publicist Steve Hannagan coined the resort's name and tagline, 'Winter sports under a summer sun,' and orchestrated the celebrity visits that made Sun Valley famous, with Ernest Hemingway becoming its most notable long-term resident. Adult daily tickets run from 89 to 149 US dollars, with season passes from 975 dollars for Dollar Mountain-only access.

When to visit Sun Valley
The 2025-26 season at Sun Valley ran from 25 November 2025 to 19 April 2026, a roughly twenty-one-week season supported by average annual snowfall of around 220 inches. While this snowfall total is moderate compared with some Pacific Northwest resorts, Sun Valley's extensive snowmaking and grooming operations have long been central to its reputation for consistently excellent surface conditions. Season dates can shift slightly year to year.
Midwinter, from December through February, typically offers the most reliable natural snowpack across Bald Mountain's advanced terrain. As an Ikon Pass destination with a nearly ninety-year history, Sun Valley draws visitors from across the country, with holiday periods bringing the heaviest crowds despite the resort's reputation for well-managed lift lines. Weekday visits generally remain calmer.
Sun Valley's identity as North America's first destination ski resort continues to shape its seasonal programming, with a heritage of celebrity visits and Hollywood-era glamour still part of the resort's marketing and atmosphere. Dollar Mountain's dedicated beginner terrain supports significant ski school and family programming throughout the season. School holiday periods bring particularly strong demand for these family-oriented offerings.
Specific event programming beyond standard lift operations and ski school is not confirmed in available resort information. The resort's long-running association with author Ernest Hemingway, who lived in the area for two decades, remains part of the broader Sun Valley and Ketchum cultural identity through the winter season. Grooming quality across Bald Mountain remains a defining feature cited consistently by visitors.

Getting there
Getting to Sun Valley, and where to stay
Sun Valley sits adjacent to Ketchum, Idaho, with a base elevation of 5,751 feet and a summit at 9,150 feet across a 3,399-foot vertical drop over 2,054 acres split between Bald Mountain and Dollar Mountain. The resort and Ketchum together form one of the most established mountain communities in the American West, built specifically around the ski resort since the 1930s.
Ketchum itself offers extensive lodging, dining and shopping befitting Sun Valley's decades-long status as a destination resort, with a level of infrastructure that has grown alongside the mountain since 1936. The broader Wood River Valley combines skiing with a resort-town culture that has attracted visitors, celebrities and long-term residents throughout the resort's history. Ketchum's compact, walkable centre sits within easy reach of the mountain itself.
Idaho State Highway 75 connects Ketchum and Sun Valley to the wider region, running north from the interstate network through the Wood River Valley. Winter driving conditions on the approach can include snow and ice, though the route is well maintained given the resort's status as a major destination. Local shuttle services within Ketchum and Sun Valley reduce the need for a vehicle once visitors arrive.
Friedman Memorial Airport in nearby Hailey, nearly the closest airport to any major US ski resort, offers direct flights from several major cities and sits a short drive from the resort itself. This convenient air access has long supported Sun Valley's role as a fly-in destination for visitors from across the country, reinforcing its identity as America's original purpose-built ski resort.

Maverick Mountain's Only Chairlift Destroyed as Sand Creek Fire Tears Through Montana Ski Area
Firefighters saved every base building at Maverick Mountain, Montana, but the resort's sole chairlift didn't survive the Sand Creek Fire. Owners Erik and Kristi Borge say the lift is "most likely" out for the 2026/27 season after flames tore through the mountain on August 8. The wildfire has since grown past 27,700 acres with zero percent containment. It's a gutting result for the tiny, one-lift operation near Dillon - though the lodge, groomers and equipment all made it through untouched.

Spain Moves to Ban Smoking at Ski Resorts Under New Tobacco Law
Spain's government has approved a draft tobacco law that would ban smoking across a wide range of outdoor spaces, including sports venues - a category Spanish winter sports media expect to cover ski resorts, potentially extending to slopes and lifts themselves. The rules would also apply to e-cigarettes and vaping devices, even nicotine-free ones. The bill still has to clear the Spanish parliament before any ban, signage, or fines can take effect.

South Tyrol Approves New 16-Person Ciampinoi Gondola in Val Gardena
South Tyrol has approved a full rebuild of the Ciampinoi cable car in Selva di Val Gardena, replacing the current 12-person gondola with a 16-person cabin and a new mountain-station restaurant. Capacity is capped at 3,200 people an hour rather than the 3,600 the operator wanted, and 250,000 euros must go toward compensatory measures. No construction or opening date has been set, though the upgrade is partly aimed at clearing bottlenecks before the 2031 Alpine Ski World Championships.

La Thuile's New Cable Car Replaces Two Ageing Chairlifts
La Thuile is spending 38.7 million US dollars on a new 10-person cable car linking Les Suches to Chaz Dura, replacing the La Combe and Chaz Dura chairlifts after nearly forty years of service. Built by Leitner, the new cable car runs 1,950 metres to a top station at 2,576 metres, carrying up to 3,000 people an hour with a six-minute ride. It also improves the connection to La Rosiere in France via the Petit-Saint-Bernard Pass, and is on track to open for the 2026/27 season.

The Remarkables Adds Scarpa Bowl to Its Inbounds Terrain
The Remarkables is adding new inbounds terrain for winter, bringing the Scarpa Bowl - known locally as the Toilet Bowl - into its lift-accessed network after years as backcountry-only ground. The roughly 500 metre run is reached by bootpacking from the top of the Sugar Bowl chairlift, with a shuttle picking skiers up from the road at the bottom. It's a smaller, faster addition than the resort's planned Doolans expansion, though the new terrain hasn't opened yet due to a lack of snow this season.

Ski Portillo Cut Off After Storm Dumps More Than 4.5 Metres of Snow
Ski Portillo remains isolated after an extended storm buried the Chilean resort under more than 4.5 metres of snow, with both ground and air access suspended since Tuesday while crews monitor avalanche hazards and worsening weather. Resort officials say further snowfall is expected in the coming days and haven't set a timeline for reopening the mountain road. Once access resumes, the scale of the snowpack could set up a strong season at one of the Southern Hemisphere's most historic ski resorts.

Understanding the Sun Valley snow report
Planning a day at Sun Valley? Our snow report combines official mountain data with live weather so you know exactly what conditions look like right now, from the 1753m base to the 2789m summit.
Snow measurements
Base depth, summit depth, and recent snowfall are the core numbers to watch. At Sun Valley, summit conditions (2789m) can differ noticeably from the base, so we break both out separately rather than showing a single average.
Weather conditions
Current weather conditions affect snow quality. Cold temperatures with low wind typically preserve snow quality, while warm temperatures or rain can impact conditions negatively — something worth watching closely at Sun Valley's 1753m base elevation, where temperatures run milder than the summit.
Data sources
Sun Valley snow data is collected through a combination of on-mountain reports and weather forecasting services, giving you both official resort updates and independent forecast data in one place. The mountain is served by 19 lifts, including 9 quad chairlifts and a 6-person chairlift.
When to check
Snow reports are typically updated early morning and late afternoon. For the most current conditions, check back regularly, especially if a winter storm is approaching.
