When the Alpine Passes Close: A Late-Season Planning Guide
Routes & Regions
Published
Almost no Alpine pass announces its winter closing date in advance — the barriers go down on a few days' notice, or none at all. Here is what the last four autumns actually show, what "closed" means in practice, and how to plan a late-season route that survives a forecast.
There is a question riders ask every September, and it has no good answer: when does the Stelvio close?
The honest reply is that nobody knows yet, including the people who will close it. Alpine road authorities do not publish autumn closure dates in advance. They close when snow arrives, usually on a few days' notice, sometimes pre-emptively ahead of a forecast, and occasionally not at all until a storm makes the decision for them. As of late September 2026, essentially no pass in the Alps has a published 2026-27 closing date.
That is not a gap in the information. It is the information, and a late-season route has to be built around it.
What four autumns actually show
Published dates are scarce, but history is not. These are the dates on which passes actually closed in recent years — evidence of the pattern, not a forecast for this year.
The early casualties — from mid-October. The Passo Gavia closed on 13 October 2025, roughly three weeks before the Stelvio a few valleys away. The Gavia is narrow, unlit and high, and it goes first. Riders who assume Valtellina passes close together get caught by this one every year.
The main wave — late October to mid-November. The Swiss high passes cluster tightly: across 2022 to 2025, Grimsel, Susten, Nufenen, Klausen and the Gotthard all closed between 30 October and 14 November. On 11 November 2025 a single weather system took Grimsel, Susten, Nufenen and Klausen on the same day. One storm can shut a region.
Elsewhere in the same band: the Stelvio closed on 7 November 2025 and 18 November 2024. The Grossglockner closed on 2 November 2025 and 10 November 2024 — the latter a weather-driven one-week extension of the original date, which cuts both ways. The Timmelsjoch closed on 2 November 2025 and 18 November 2024.
France runs on its own calendar. The Col de l'Iseran is the rare pass with a published schedule: it closes, in the words of the local tourist office, "usually starting on the first Monday in November", and the 2026 closure is listed as Monday 2 November — scheduled and weather-dependent, not guaranteed. The Galibier is a documented early closer and the Savoie département has a standing category for fermeture hivernale anticipée, early winter closure. The Bonette, southernmost of the group, was still open day and night in mid-September 2026 and typically holds on longest.
The working rule. After roughly 1 October, treat every pass above 2,000 m as provisional. After 1 November, assume closure and verify the exception. A trip planned for the second week of November is a trip planned around passes that may already be shut.
"Closed" means several different things
This is where late-season plans go wrong, because the word covers four situations that behave very differently.
Barrier closures. Gates are locked at the bottom of the maintained section — which is often a long way below the summit. The Stelvio closes from Trafoi upward; the Gavia between Santa Apollonia and Plaghera; the Galibier from Bonne Nuit. You do not arrive at a pass and find it shut. You arrive at a barrier, kilometres short, and turn around. Riding past one is an offence and will void insurance.
Gated toll roads. The Grossglockner and the Timmelsjoch are commercial roads with staffed booths. When they close, they close absolutely.
Unmaintained but not barriered. Some sections simply stop being cleared, gritted and patrolled. Legally passable. Practically not — no maintenance, no recovery, often no signal.
Partial and staged closures. The most under-reported category. One side can close before the other: in 2025 the South Tyrol side of the Stelvio shut on 31 October, a full week before the road closed completely on 7 November. Old parallel roads close separately from modern ones — the Gotthard's cobbled Tremola has its own dates and reopened nine days after the main pass in May 2026. Tunnels close separately from the col above them, which is exactly the Galibier's arrangement.
Insider tip. Reopening is not closing in reverse. Passes reopen in stages — the Furka opened as far as Tiefenbach before full release in May 2026, and the Susten opened to Sustenbrüggli with the pass itself still shut weeks later. "Open" on an aggregator site can mean "open to a car park halfway up".
The trap that has nothing to do with snow
More October riders are caught out by opening hours than by the seasonal closure.
The Grossglockner Hochalpenstrasse operates a statutory night-driving ban. From 1 September its hours are 06:00 to 19:30, last entry 18:45, and in late October in recent years they have dropped further, to 08:00–17:00. The road is gated outside those hours. The Timmelsjoch is gated too, open 07:00 to 20:00 even in high season.
A route that has you cresting either pass at seven in the evening in October does not work, regardless of whether the pass is officially open.
The Dolomites exception, and its limits
Passo Sella, Passo Gardena, Passo Pordoi and Passo Campolongo have no scheduled winter closure. They are kept clear because they serve the Sella Ronda ski circuit, and they are listed as open year-round.
Maintained is not the same as guaranteed. They shut without notice during heavy snowfall and avalanche risk, and winter tyre and chain obligations apply — obligations written for cars, which a motorcycle cannot satisfy. Riding them in December is legal and occasionally possible. It is not something to build a route on.
Nearby, Passo Fedaia and Passo Giau are seasonal and close on the normal pattern. Passo Valparola stays open year-round.
Car-free days: not a motorcycle rule, but it stops motorcycles
There is a persistent belief that the Stelvio has recurring motorcycle-restricted Saturdays. It does not. There is no weekly or monthly scheme.
What exists is a small number of one-off car-free cycling events, run by different bodies on different sides of the mountain. In 2026 there were two on the Stelvio: the Stelvio Bike Day on 29 August, closing Trafoi–summit–Bormio plus the Swiss Umbrail side from 08:00 to 16:00, and Enjoy Stelvio Valtellina on 19 September, Bormio side only, 09:00 to 13:00. The Gavia had its own dates in June and August. The Sellaronda Bike Days closed Gardena, Sella, Pordoi and Campolongo on 6 June and 12 September, 09:00 to 16:00.
The closures are worded as chiusura al traffico motorizzato — closed to motorised traffic. Motorcycles are not singled out, and they are not exempt.
Dates already published for next year: Stelvio Bike Day, Saturday 28 August 2027, and Sellaronda Bike Days, Saturday 5 June and Saturday 11 September 2027. Worth pinning now if a 2027 Alps trip is forming.
Insider tip. Organisers of the Sellaronda days warn that police may hold the roads closed past the scheduled reopening if cyclist volume is high. A rider timing an arrival for 16:01 is timing it too finely.
Where to check, by country
Pass status is national, sometimes regional, and the aggregators lag. These are the sources that decide.
Switzerland — the TCS pass portal covers 77 passes with live status and the customary closure window for each; alpen-paesse.ch holds the best historical open/close tables; Canton Uri publishes road info for the Furka, Susten, Klausen and the Gotthard's north approach, with the useful disclaimer that its own dates carry no guarantee.
Austria — the Grossglockner and Timmelsjoch operators publish live status, hours and snow clearing on their own news pages. ÖAMTC carries a general closures map.
Italy — the Autonomous Province of Bolzano's traffic bulletin covers the Stelvio's north side and the Dolomite passes; ANAS covers the Lombardy side of the Stelvio and the Gavia; Valtellina Mobile reports the Stelvio and Gavia reliably and early.
France — each département runs its own inforoute, and this is what riders get wrong most often. Savoie covers the Iseran, the north side of the Galibier and the Petit Saint-Bernard. Hautes-Alpes covers the south side of the Galibier and the Izoard. The Bonette is split between Alpes-de-Haute-Provence and Alpes-Maritimes.
A routing app is not a status source. Most will quietly route you around a closed pass without telling you why, and the first you know of it is a barrier.
Plan for the alternative, not just the route
The practical answer to a late-season Alps trip is not a better forecast. It is a route with a valley-floor version already drawn.
Build the high line, then build the fallback that gets you to the same bed without the pass, and know the point on the map where you have to choose between them. In October that decision is usually made the evening before, on a weather forecast, not at the barrier.
The Travel Riders route planner is built for exactly this kind of replanning: segments can be re-tuned one stretch at a time without touching the rest of the route, so swapping a pass for its valley alternative does not mean redrawing the day. Export both versions to GPX and carry them on the bike.
Road status changes daily in autumn. Every historical date above is a record of what happened, not a prediction of what will. Verify against the authority for the pass before you ride.
