History
One&Only's first American address, and its first outdoor-adventure resort, opened in 2025 at Moonlight Basin in Big Sky. The brand is known for houses in Mauritius, Rwanda, and Malaysia; here the team books activities and runs guests between lodges on a side-by-side ATV.
Guests reach the slopes on a private One&Only gondola, with locker rooms, tuning equipment, and rentals that impress even members of Yellowstone Club next door. The 240-acre estate sits in the Greater Yellowstone Ecosystem, linking protected wilderness used as moose and bobcat migration routes. Fly-fishing, a private observatory, and a 17,000-square-foot Chenot Spa fill the months when the snow is gone.
The setting
Situated between Lone Peak and the Spanish Peaks in Big Sky, Montana, within the Greater Yellowstone ecosystem. Big Sky Resort has 5,850 skiable acres, among the largest in North America. Approximately 50 miles from Bozeman Yellowstone International Airport.
