One&Only Moonlight Basin opened on November 18, 2025, with Sam Byrne of CrossHarbor Capital and Lone Mountain Land Company president Matt Kidd cutting the ribbon while staff circulated champagne. Press coverage called it a luxury hotel opening. That framing is accurate and nearly useless if you already live here.
What actually arrived in Moonlight Basin was a cluster of neighborhood venues that happen to share a campus with 73 hotel rooms. Three of the four restaurants are open to anyone who makes a reservation. So is the bar. The speakeasy cabin under the trees is available to the public. The observatory can be booked for a private session with a professional astronomer. None of that requires a hotel stay at ski-season rates that begin around $2,300 a night.
The distinction between "a hotel you can see from your driveway" and "a set of dinner reservations, a bar with live music, and a speakeasy worth visiting in March" is the whole point of this post.
What Opened, and Where Each Piece Sits
The property covers 240 acres and was designed by Tom Kundig of Olson Kundig, the Seattle firm whose work you know from its refusal to let buildings compete with the land around them. The low-rise layout keeps Lone Mountain's northeast face and Fan Mountain visible from nearly every point on the campus, a deliberate choice that reads as architectural humility. Borders by 17,000 acres of protected open space, the property sits at enough of a remove to feel like wilderness while still connecting to Big Sky Resort via a heated private gondola that reaches the Madison Base in five minutes.
That gondola is worth naming precisely because One&Only is not ski-in/ski-out in the way Moonlight's residential properties are. The gondola is the workaround, and it functions well enough that the distinction is mostly academic on a powder morning.
Four food and beverage venues anchor the main lodge. Wildwood is the all-day dining restaurant, built around ranch-to-table sourcing, with a full breakfast buffet and a dinner menu drawing from Montana's agricultural and wild game traditions. Dear Josephine is the lobby bar: live music runs through the space at night, and the room functions as the social center of the lodge in a way that a hotel bar rarely does. The Landing, located in the separate Sky Lodge building uphill from the main lodge, serves hearty globally inspired fare — the kind of room suited to a late lunch after a hard morning.
Then there is Akira Back. Back is a former professional snowboarder who became a celebrity chef with restaurants across Asia, the Middle East, and now here. His Japanese-Korean restaurant was designed by AvroKO; the walls are finished in shou sugi ban, the Japanese technique of charring wood, and punctuated with paintings by Back's mother. The result is the most visually distinctive dining room in Big Sky. As of opening week, it is open to the public — no room key required.
The Moonshack Is a Different Kind of Amenity
Most of what One&Only calls amenities follows a predictable five-star script. The spa runs 17,000 square feet across two floors, with eight treatment rooms, an oxygen bar, an indoor lap pool, an outdoor onsen, treatments using Augustinus Bader products, and a nail program by Bastien Gonzalez. Competent, expensive, exactly what you'd expect.
The Moonshack is not that. Tucked under a thick canopy of conifers away from the main lodge, it is a freestanding speakeasy cabin with live country music, poker tables, and cigars. The design decision to build something deliberately low-key — a cabin that reads as a local bar rather than a resort lounge — says something about how Lone Mountain Land Company calibrated One&Only's social spaces. When Sam Byrne spoke at the ribbon cutting, he described learning about this land from Kevin Germain, VP of Moonlight Basin, which is another way of saying this property was conceived from inside the community rather than dropped onto it. The Moonshack is the clearest evidence of that.
The Observatory
A level above a good bar: One&Only includes a private observatory where residents and guests can book stargazing sessions with a professional astronomer on site. At this elevation, with 17,000 acres of protected land limiting ground-level light competition, the conditions are legitimate. It is the sort of amenity that takes thirty seconds to describe and is worth doing once a season, especially in the transition weeks between winter and spring when the sky clears and the nights stay cold.
What Changes When the Gondola Goes Quiet
The resort's pitch to year-round residents runs through two private alpine lakes called Lee's Pools. Summer programming at One&Only includes hiking, mountain biking, fly fishing, and paddleboarding on Lee's Pools. The transition from ski season to summer is literal: the ski shop converts to a fly-fishing outfitter each spring, which means the staff who handled boot fitting in February are handling rod rentals in June.
Big Sky was named Expedia's top trending destination for 2026, following 13.7 million visitors to Montana in 2024. Those numbers reflect what has been accumulating here for several years — the Montage opened, then One&Only, and the town's profile has shifted from a skier's local secret to a recognized international destination. The practical consequence for Moonlight Basin residents is that Akira Back will be harder to book next January than it was in November 2025, when the property was still finding its footing. Reservations made now, before the full weight of that destination pressure arrives, are the smarter play.
The Service Structure and Resident Access
One&Only operates on a host system: each hotel guest receives a two-person team accessible by text around the clock for logistics, rides, and in-room dining orders. The three-to-one staff-to-guest ratio that One&Only maintains across its portfolio applies here, which means the restaurants operate at a different pace than anything else in Big Sky. A kitchen staffed to One&Only's standard is a different kitchen than one running on seasonal volume.
Developer planning communications noted that Moonlight Basin residents receive preferential reservations at the resort's dining venues — a detail worth confirming directly with the property before peak season, since the preference structure is not published anywhere prominent.
One Number Worth Setting in Context
Entry-level rooms at One&Only start at 725 square feet, which is larger than most US hotel suites. Ski-season rates open around $2,300 per night inclusive of taxes and fees. The comparison is not about whether to stay there. It is context for understanding the kitchen and staffing economics that make a dinner reservation worth the drive, even when you are sleeping three miles away in your own home. A restaurant operating within a five-star hotel's cost structure is a materially different operation than one built to serve tourist traffic for eight months.
One&Only Moonlight Basin is the brand's first property in the United States and its first ski resort anywhere in the world. General Manager Serge Ditesheim said at the opening that building it required "an extraordinary team" and reflected deep respect for this land. The Olson Kundig architecture makes that claim legible from outside: buildings set low against the terrain, windows positioned to frame Lone Mountain, no structure asserting itself over what was already here.
What It Adds Up To
What opened November 18, 2025, is not an amenity you appreciate from a distance. It is a dinner reservation at Akira Back, a night at Dear Josephine when the pianist is good, a cigar at the Moonshack when the conversation runs long, an observatory booking for mid-March, and a fly-fishing outpost that will matter from June onward. The hotel guests fill the rooms. The neighborhood fills the venues. Those are two different things happening in the same building, and if you live in Moonlight Basin, only one of them applies to you.
Life in Big Sky has been in this market through every phase of its development. If you want to talk about what Moonlight Basin ownership looks like in the context of what just opened around it, we are ready.
