In Big Sky’s alpine landscape, One&Only Moonlight Basin spreads across 240 acres on the edge of the Greater Yellowstone ecosystem. Tom Kundig’s architecture pairs weathered timber, local stone and deep overhangs with rooms, suites and cabins shaped around fireplaces, mountain views and substantial bathrooms. Akira Back, Wildwood, The Landing and Dear Josephine provide contrasting places to eat and gather after days on the slopes or trails. The 17,000-square-foot spa includes a saltwater pool and outdoor onsen, tucked among pines below the surrounding peaks.
