Set on 240 secluded acres in Big Sky, Montana, One&Only Moonlight Basin marks the luxury brand's first U.S. resort and its first alpine property worldwide. The resort opened in November 2025, positioned on the northwest side of Lone Mountain within the larger 8,000-acre Moonlight Basin community. Protected land surrounds the property on all sides (over 17,000 acres of it), creating a buffer between guests and the outside world. Yellowstone National Park sits about an hour south, while Bozeman Yellowstone International Airport is roughly an hour north.
This is not a typical ski resort. Designed by Olson Kundig, the architecture uses timber, stone, and floor-to-ceiling glass to bring the mountain environment inside. Views extend to Lone Mountain, Fan Mountain, and the Spanish Peaks. A private heated gondola connects guests directly to Big Sky Resort's Madison Base, providing access to over 5,800 acres of skiable terrain without fighting for parking or shuttle seats.
One&Only Moonlight Basin offers several ownership and accommodation options. The resort includes 73 guest rooms and suites spread across multiple lodges (Main Lodge, East Lodge, and West Lodge), 19 standalone cabins, and 62 private homes. Eight private estate lots remain available for custom builds.
Here's how the options break down:
Lodge Rooms and Suites: The Main Lodge, East Lodge, and West Lodge house hotel-style accommodations with timber and stone interiors, fireplaces, private balconies, and views of the surrounding peaks. King suites include separate living areas. Family configurations are available through interconnecting rooms.
Standalone Cabins: The 19 guest cabins offer more privacy than lodge rooms, with multiple fireplaces, private decks, hot tubs, and spa-style bathrooms. These function as standalone residences while still providing access to all resort services.
Private Homes: The 62 private homes range from five to six bedrooms, spanning approximately 5,600 square feet across three levels. Each features expansive outdoor terraces, gourmet kitchens, fire pits, hot tubs, and panoramic mountain views. Homeowners receive access to resort amenities, services, and global One&Only privileges.
Private Estate Lots: Eight lots remain available for custom construction. These offer the most privacy and flexibility, allowing buyers to build homes tailored to their specifications while maintaining full access to the One&Only ecosystem.
The architecture throughout reflects Olson Kundig's signature style: buildings sit low to the land, using local materials and floor-to-ceiling windows to minimize the barrier between interior spaces and the mountain environment. The design philosophy prioritizes views, natural light, and integration with the surrounding forest and peaks.
Local Tip: Homeowners at One&Only Moonlight Basin gain access to privileges across the entire One&Only global portfolio, which includes 15 resorts in destinations like the Maldives, Dubai, Greece, and Mexico.
Dining
The resort operates six restaurants and bars, making it possible to eat exceptionally well without leaving the property. Akira Back serves modern Japanese cuisine (the chef's first alpine location among his 30+ global restaurants), featuring dry-aged steaks, prime wagyu, and seafood flown in from Japan. Early reviews suggest it may be the finest restaurant in Montana.
Wildwood focuses on ranch-to-table cooking with locally sourced ingredients, serving breakfast daily and dinner. The Landing, located at the Sky Lodge near the gondola, offers elevated American comfort food and draws both resort guests and Big Sky skiers.
For drinks, Dear Josephine is a speakeasy-style cocktail bar named after a local Prohibition-era moonshiner. Moonshack, a converted cabin in the woods, serves rare whiskeys and cigars by a wood-burning stove. A grab-and-go counter at Sky Lodge handles coffee and pastries.
Skiing and Winter Activities
Big Sky Resort claims the title "Biggest Skiing in America" with over 5,800 acres of skiable terrain, 4,350 feet of vertical drop, and access to four mountains. The resort's heated gondola delivers guests to the Madison Base in about five minutes, avoiding the traffic and parking hassles that plague other major ski areas.
Lone Mountain rises to 11,166 feet, with terrain spanning all ability levels: 15% beginner, 25% intermediate, 42% advanced, and 18% expert. The Lone Peak Tram accesses some of North America's most challenging lift-served terrain, including triple-black-diamond chutes and couloirs. Average annual snowfall exceeds 400 inches.
Beyond downhill skiing, the resort offers guided snowshoeing, Nordic skiing on over 15 miles of trails, fat tire biking, and snowmobile excursions into Yellowstone.
Summer and Year-Round Activities
When the snow melts, the trail network opens for hiking and mountain biking. Lee's Pools (the resort's two private lakes) offer trout fishing and stand-up paddleboarding. Guided fly-fishing on the Gallatin and Madison Rivers is arranged through the resort's activity center.
The proximity to Yellowstone enables day trips for wildlife viewing, geothermal features, and backcountry exploration. The park's West Entrance at West Yellowstone is about 50 miles south of Big Sky.
Wellness and Spa
The 17,000-square-foot One&Only Spa includes eight treatment rooms, sauna and steam facilities, an oxygen bar for altitude recovery, and an indoor lap pool with retractable glass walls. Outdoor amenities include heated pools and cold plunge facilities. The spa partners with Augustinus Bader for skincare and Bastien Gonzalez's Pedi:Mani:Cure Studio for nail treatments. A fitness center and yoga deck round out the wellness offerings.
The Surrounding Area
Big Sky's three distinct areas (Canyon, Meadow, and Mountain Village) provide additional dining, shopping, and services. The Meadow Village features the Town Center with restaurants and boutiques. Mountain Village, at the base of Lone Mountain, offers ski-in/ski-out lodging options and more dining.
Bozeman, an hour north, offers a full-service airport with direct flights from 21 airports across the U.S. The city has a lively downtown with over 100 shops and restaurants, galleries, and Montana State University.
The bottom line? One&Only Moonlight Basin positions itself at the very top of the Big Sky luxury market, combining ultra-luxury hospitality with direct access to world-class skiing and Yellowstone proximity. For buyers seeking the ultimate mountain retreat with global-brand service standards, this is the benchmark property in the region.
