Which Ski Resorts Have the Longest Seasons?

For someone planning a week's holiday, a ski resort's season length barely matters — you'll book around it. For a seasonaire, it's arguably the most important single number in the database. Season length is your income window. It determines how many paycheques you collect before the lifts close and the jobs disappear.

The difference between a 120-day season and a 180-day season is roughly two months of wages. At €1,800/month — a reasonable gross for resort work in France — that's €3,600. It's the difference between finishing a season with savings or finishing it having broken even.

This is why Seasoned.info's leaderboard for longest seasons weights season length at 25% of the overall Seasoned Score — higher than any other single factor. Here's what the data actually shows.

The Glacier Resorts That Open Earliest and Close Latest

Glacier resorts operate on a different calendar to snow-dependent resorts. They're not waiting for seasonal snowfall — the glacier is there year-round. That fundamentally changes the employment proposition.

Hintertux, Austria is in a category of its own: it runs lifts every single month of the year. The Hintertux Glacier in the Zillertal sits above 3,250m and gets enough natural snowfall that summer skiing is genuine, not just a novelty on a sliver of ice. As an employment destination it's niche — the resort is small, the job market limited — but for a skier who can find work in the valley and commute up, you're looking at a 12-month ski access window. No other resort in Europe comes close.

Val Thorens (highest resort in the Alps at 2,300m base) typically opens in late October and closes in early May — around 180–190 days. That's the longest standard winter season in the French Alps, not counting summer glacier operations. Opening weekend at Val Thorens in late October is a genuine event; the resort often has 70%+ of its lifts running by early November when most resorts in the Alps aren't open yet. See the Val Thorens resort page for current season stats.

Tignes operates similarly — the Grande Motte glacier keeps Tignes running from October through May, and in some years the summer skiing on the glacier gives a brief June window too. Tignes and Val Thorens are in many ways the benchmark for "longest viable season employment" in Europe. Both have significant staff accommodation infrastructure because they're purpose-built stations; neither has much of a non-tourist local economy, which matters when you're assessing cost of living beyond your accommodation package.

Les Deux Alpes runs glacier skiing from June through August on the Dôme de la Lauze — which means it technically operates year-round across two separate seasons. In practice this means some seasonaires do a winter season (roughly December–April) and then return for summer glacier work, effectively stacking two employment windows in the same calendar year. The terrain in winter is extensive (225km of pistes) and the vertical from the glacier at 3,568m to the valley at 1,650m gives you one of the biggest verticals in the Alps.

Saas-Fee, Switzerland deserves a mention but with an asterisk. The glacier has lifts running most of the year, but the ski area is compact — around 100km of pistes — and the Swiss working permit situation limits your options if you're non-EU. For EU nationals with the right employer lined up, it's a genuine long-season destination. For everyone else, the admin burden doesn't match the payoff.

North America: Whistler vs. Mammoth

The North American picture looks different. Most Rockies and Pacific Northwest resorts run roughly November to April — five months, sometimes less at lower-altitude resorts in marginal snow years.

Whistler Blackcomb is typically a late-November to late-April operation, around 150 days. In good snow years Blackcomb's glacier terrain pushes this into May. It's the North American benchmark for reliable season employment — the resort is large enough to weather a bad January and still have full operations. Whistler Blackcomb resort page.

Mammoth Mountain in California is the outlier. In good snow years — and the Eastern Sierra gets genuinely massive snowfall totals — Mammoth has historically stayed open into June and occasionally July. The 2023 season ran to August. That's exceptional and not something you can bank on when planning a season, but it's happened enough times to be a real factor. Mammoth sits at a high base elevation (2,424m) and the terrain above 3,300m holds snow when everywhere else in California has closed. For a seasonaire, the upside case at Mammoth is a genuinely extraordinary season length; the downside case in a low-snow year is a shortened season that closes in April like most resorts. You're taking on variance. Mammoth Mountain resort page.

Japan: December to May and the Case for Late-Season Powder

Niseko in Hokkaido runs roughly December through May — about 150–160 days in a good year. What makes it interesting from a season-length perspective isn't just the calendar; it's that late-season Hokkaido powder is one of the best-kept secrets in skiing. March and April at Niseko can have exceptional conditions that European resorts can only produce in exceptional years. Some seasonaires who do a European winter December–April then head to Japan for March–May, chasing the tail of Hokkaido's season after returning from the Alps. The seasons overlap in a way that makes sequential seasons workable for the right person.

The Southern Hemisphere Arbitrage

Southern Hemisphere resorts — Queenstown/Remarkables/Coronet Peak in New Zealand, Portillo and Valle Nevado in Chile, Perisher and Falls Creek in Australia — run June through October. That's a shorter window, typically 100–130 days, and the terrain doesn't match the Alps or North America at the top end.

What it does enable is back-to-back winters. A seasonaire who works a northern hemisphere season (November–April) can fly south in late May and be skiing in New Zealand by June. Two winters in one calendar year isn't for everyone — it's a specific lifestyle choice — but for skiers and riders who want to maximise time on snow and don't need a summer, it's a genuine option that the season-length data makes legible.

The Number That Matters

When comparing resorts for a season, treat season length not as a nice-to-have but as a multiplier on everything else. A cheaper resort with a 180-day season often outperforms a prestigious resort with a 120-day season on total income, even after higher living costs are factored in. Run the numbers before you commit.
