Big Sky Resort5,850 skiable acres on Lone Peak — the country's biggest ski resort, 4,350-foot vertical, the Lone Peak Tram to 11,166-foot summit

Big Sky Resort opened December 1973 — the dream of NBC anchor Chet Huntley, who retired from the Huntley-Brinkley Report in 1970 and began assembling a Madison Range ski-area lease before his death in 1974. The resort sits 50 miles south of Bozeman in southwestern Montana, anchored by the 11,166-foot Lone Peak — a granite summit that dominates the upper Madison drainage. The 2013 merger with Moonlight Basin and the 2015 Spanish Peaks acquisition created the largest contiguous in-bounds ski terrain in the United States: 5,850 acres, 4,350 feet of vertical, and 320 named runs across four interconnected mountains (Lone Mountain, Andesite Mountain, Flat Iron Mountain, and the Spanish Peaks side). Boyne Resorts has operated Big Sky since 1976.

The Lone Peak Tram is the headline lift. The original 1995 fifteen-passenger tram was replaced in December 2023 with a two-cabin, 75-passenger-each "Tram 2.0" — uphill capacity tripled overnight, end-of-line waits dropped from 90 minutes to 20 in peak season. From the 11,166-foot summit, skiers drop into the 50-degree Big Couloir (the most photographed run in Montana, mandatory beacon-shovel-probe sign-out at ski patrol), the equally steep Lenin and Marx Couloirs (named for the political subdivision of the time), the wide-open Headwaters and Liberty Bowl, and — for non-experts — the long blue Liberty Bowl Traverse that cuts back to the lower mountain. Below the tram, the Swift Current 6 chair (the new 2023 high-speed bubble six-pack) and the Powder Seeker 4 cover roughly 2,000 acres of intermediate terrain. The Madison and Six Shooter Express on the Spanish Peaks side are quieter and groom out perfectly for cruisers.

Plan to stay in Big Sky Mountain Village (slopeside, expensive), Big Sky Meadow Village (a 7-minute shuttle ride down the canyon, half the price), or West Yellowstone (45 minutes south, cheapest, gateway to Yellowstone in summer). Bozeman Yellowstone International Airport (BZN, 50 miles north) connects through Denver, Salt Lake, Minneapolis, Dallas, and JFK. Ikon Pass holders get 5–7 unrestricted days. Walk-up day-pass rates routinely hit $269; book 14+ days ahead online for the $199 tier. The free Skyline Bus runs Bozeman to Big Sky Mountain Village December–April. Backcountry gate access requires beacon, shovel, probe, and same-day check-in with patrol at the top of the tram.
