The Cairn Guide
Every major ski resort, on one map
North America, Japan, the Alps, the Andes and beyond: which pass gets you there, how big the mountain is, how good the snow really is and the weeks worth booking. Tap a marker or a card for the full breakdown.
How to read the numbers
Snow score
A 0 to 100 reliability score from ZRankings, which weights true measured snowfall, how often it dumps six inches or more, how many months fall below 30 inches, and how well the slopes hold snow (north-facing terrain keeps powder soft far longer). Scores above 85 are the best snow on the continent. ZRankings only covers North America, so resorts elsewhere (and Eastern hills it skips) get an estimate from reported snowfall and the PowderHounds snow rating, marked "est."
2026-27 outlook
A consensus of seasonal models (NOAA, the European ECMWF model, the Copernicus multi-model, the Japan Meteorological Agency and national weather services) and snow forecasters (OpenSnow, Chris Tomer, WeatherBELL and regional specialists), plus how past strong El Niño winters played out. Each source's lean is averaged for the resort's region. Snowfall compares the expected season with normal. Quality follows temperature: colder means lighter snow and lower snow lines. Confidence drops when sources are few or disagree. Southern Hemisphere outlooks arrive in spring 2027.
PowderHounds ratings
Zero to five scores from the PowderHounds editors across terrain, snow, lifts, crowds, family friendliness, food, nightlife, ski-in ski-out and cost. The Powderhounds score weights advanced terrain, powder and uncrowded freshies; Overall weights everything. Resorts they have not reviewed show no rating.
Passes
Ikon and Epic access is for the current season, including their international partners. "Unlimited" means no day cap on the full pass; a day count means that many days with the pass, and most have blackout dates on the cheaper tiers. Mountain Collective gives two days at each destination; Indy Pass gives two days at each independent hill. Always confirm on the pass site before you buy.
Mountain stats
Acres, vertical, lifts and run mix come from each resort's published mountain statistics. European, Japanese and Southern Hemisphere resorts usually publish kilometres of marked piste instead of acres, so those cards show piste miles (and the map sizes them to match). Linked areas like the 3 Vallées or Niseko United are shown as one resort. Run mix is by percent of terrain where resorts publish it, otherwise by run count. The best window is our read on when snow quality and crowds line up best for that region, not a guarantee.
