If your ski crew argues every morning about whether to lap groomers, hunt powder stashes in the trees or test their nerve on steeps, SKI Magazine's annual Reader Resort Survey has a shortlist for you. Its latest terrain-variety rankings — drawn from reader scores out of 10 — put 10 Western resorts at the top, and the winner is Big Sky, Montana, with a 9.24.
Big Sky scored for its sheer scale and range: inbounds terrain for every level, plus sidecountry and backcountry options, all wrapped around a village readers called the best in skiing, with plenty of ski-in/ski-out lodging. The flip side? Access and parking can be a pain.
Canada takes two spots in the top five. Banff Sunshine (8.98) earned praise for high-elevation snow quality that lasts a very long season, with readers citing everything from off-piste lines and couloirs to beginner-friendly cruisers. Lake Louise (9.11) followed just behind, with freeride terrain off Eagle Ridge and Whitehorn II, glades in West Bowl, short lift lines and free close-in parking.
Colorado dominates the middle of the list. Vail scored 9.17, with readers saying it covers "every type of terrain you can imagine" and spreads crowds thin. Snowmass hit 8.61, lauded for easy navigation and slope-side lodging you can ski straight out of. Telluride (8.73) stood out for steep, varied terrain and barely any crowds, with the town and Mountain Village linked by gondola.
Utah's Cottonwood Canyons both made the cut: Alta (8.82) impressed despite just five lifts, thanks to an outsized variety of terrain and top-tier snow — no snowboarders, which some readers count as a feature. Neighbour Snowbird (8.55) scored for challenge and big-storm snow, with strong grooming saving thin seasons. Snowbasin (8.78) rounded out the Utah picks, with easy road access, an upscale lodge scene, gondolas, a tram and food readers rave about. Finally, California's Mammoth Mountain (8.86) earned its place through sheer reliability — its elevation keeps the season running when other resorts are hurting, with steeps, long groomers and multiple beginner zones.
The pattern across all 10: readers reward mountains where a mixed-ability group can split up and reconvene happy, and where a week-long trip never repeats itself. The trade-offs are consistent too — value and lodging come up as weaknesses again and again, so expect to pay for the variety.
For anyone planning a North American ski holiday this winter, this list is basically a decision matrix. Prioritise convenience and snow reliability? Snowbasin or Mammoth. Want atmosphere and steeps without crowds? Telluride. Travelling with a mixed crew and a big budget? Big Sky or Vail. And if you're a dedicated two-planker or a snowboarder, note that Alta remains ski-only, so pair it with Snowbird or Snowmass instead.
