Getting to Oz-en-Oisans: car, train, plane, shuttle

You’ve found the chalet, locked the dates, gathered your crew — which leaves the question everyone eventually asks in the group chat: “so, how do we actually get there?” Good news: Oz-en-Oisans is far more reachable than you’d expect for a mountain village at 1,350 metres. Just under an hour from Grenoble, two hours from Lyon, linked by train, regional coaches and several airports, it can be reached with or without a car. From our chalet we watch families arrive by saloon car every Saturday, clubs in minibuses, couples off the train at Grenoble, even British guests fresh from the plane the night before. Here, option by option, is how to reach Oz stress-free — with the times, the costs and the traps to avoid.

By car: the route, step by step

The car remains the most flexible way to reach Oz, especially in a group and loaded with ski gear. The principle is simple: you first reach Bourg-d’Oisans, the small capital of the valley, then climb up to the resort.

From Grenoble, count about 55 kilometres and a good hour. Take the A480 motorway, then the “Vizille – Oisans resorts” exit to join the N85 (Route Napoléon) towards Vizille, Séchilienne and the Chambon lake. At Bourg-d’Oisans you leave the valley to climb: either straight up to Oz on the resort road, or towards Allemond for the gondola solution (more on that below).

From Lyon, allow around 150 kilometres and 2 hrs 10 via the A43 then the A48 to Grenoble, before joining the route above. From Marseille or the south, come up the A51 through Sisteron (allow 3 to 3.5 hours). And from Paris, it’s a full day’s drive: nearly 600 kilometres and 6 hours via the A6 then the A48 to Grenoble.

The final stretch — the climb from Bourg-d’Oisans to Oz — is a classic mountain road with hairpins, fully paved and straightforward in dry weather. It’s mainly when there’s snow that it calls for a little care and, above all, the right equipment.

The mandatory winter equipment (mountain law)

This is the point not to overlook. Oz-en-Oisans is one of the Oisans communes covered by France’s “mountain law”: from 1 November to 31 March, your vehicle must be equipped to handle snow. In practice, you have a choice:

• approved 3PMSF winter tyres (the snowflake-in-a-mountain pictogram, often alongside the “M+S” marking);
• or, failing that, carrying removable anti-slip devices — metal chains or “snow socks” — enough to fit at least the two driven wheels.

The rule isn’t there to trap holidaymakers, but to stop an unequipped vehicle from ending up sideways and blocking the whole road on a snowy day. In practice, if you rent a car for winter, explicitly ask for winter tyres; and if you’re driving up in your own unequipped vehicle, slip a set of chains in the boot and practise fitting them before you leave, not in the cold at the roadside.

Where to park in Oz (or below, for free)

Two strategies await you once at the top. The first: drive up to the village. Oz has public car parks; count on the order of €45 for the week for a space about 50 metres from the chalet, ideal for unloading luggage and groceries.

The second, much loved by our guests: leave the car below, in the free covered car park at Allemond, and finish by gondola. We detail this option next — it’s often the smartest, especially with several cars.

The gondola trick: park at Allemond, ride up in 8 minutes

Since late 2020, a “valley lift” has changed the game: the Eau d’Olle Express links Allemond (728 m) to Oz-en-Oisans (1,350 m) in 8 minutes, with a large free covered car park at the base. The pedestrian ticket costs a few euros, and access is included in ski passes, day and stay alike.

For a holiday, the appeal is twofold. First, logistics: instead of driving eight cars up the mountain road on a busy Saturday, you gather them in the car park below and ride up in peace, sheltered from the snow. Second, the car stays covered all week — no windscreen to scrape on departure. Many of our groups adopt the winning combination: one car goes up to the village for the luggage, the whole rest of the crew parks at Allemond.

We’ve devoted a full guide to this solution — timetables, fares, how it works summer and winter — in our article on the Eau d’Olle Express gondola from Allemond. One thing to remember: it doesn’t run in spring or autumn, when you drive up to Oz by road.

By train: Grenoble, then up

Coming by train is simpler than people think, and it’s often the choice of groups travelling from afar. Grenoble station is the natural arrival point: it’s linked to Paris by TGV (about 3 hours), to Lyon in an hour, and to the wider TER network. From there, it’s just the climb into the Oisans that remains.

Three options for the final leg:

• The Cars Région Isère coaches (formerly Transisère), with line T75 between Grenoble and Bourg-d’Oisans (via Vizille), and connections to Alpe d’Huez (T76) or Les Deux-Alpes (T73). This is the regional public network — affordable, running year-round.
• The Transaltitude shuttle, which specialises in serving the resorts and links Grenoble bus station to Alpe d’Huez.
• A taxi or private transfer from Bourg-d’Oisans for the very last part of the journey, handy in a group.

In summer, Oisans shuttles also run across the valley floor (Allemond, Le Bourg-d’Oisans, Venosc), with room for bikes — useful for a car-free arrival in the warm season.

By shuttle from Grenoble: Transaltitude

For those wanting a direct, change-free journey, the Transaltitude shuttle is the go-to. In winter, it links Grenoble bus station to Alpe d’Huez daily in about 1 hr 45, with several departures a day and fares from around €14.50 one way. A luggage allowance is usually included, which matters when you’re travelling loaded with ski gear.

From Alpe d’Huez or Bourg-d’Oisans, you then reach Oz by connection, taxi or a car sent to pick you up. Timetables and stops are set season by season: check the Transaltitude website and that of the Cars Région Isère before you leave, as frequencies vary between peak and off-peak.

By plane: four possible airports

Coming from further afield, or from abroad? Four airports frame the Oisans, each with its strengths:

• Lyon-Saint-Exupéry (LYS) — about 150 km, 2 hours’ drive. The largest, open year-round, with the most flights and international connections. Often the best choice.
• Grenoble-Alpes-Isère (GNB) — about 105 km, 1 hr 30. The closest, but mainly active in winter (charter and low-cost flights over the ski season).
• Chambéry (CMF) — about 130 km, 1 hr 50. Handy in winter, with seasonal flights to the resorts.
• Geneva (GVA) — about 215 km, 2 hrs 45. A major international hub, worth it for long-haul despite the distance and the border crossing.

From these airports, shared shuttles head up into the Oisans on winter Saturdays. The Ben’s Bus service, for instance, links Lyon-Saint-Exupéry to Alpe d’Huez and Bourg-d’Oisans every Saturday of the ski season, with a connection towards Oz-en-Oisans; advertised prices start at a few dozen euros per person return. Book early: Saturday slots go fast in peak season.

• Year-round arrival: Lyon-Saint-Exupéry, the most reliable.
• Closest in winter: Grenoble-Alpes-Isère.
• From abroad: Geneva for long-haul flights.
• Airport shuttle: Ben's Bus on Saturdays in season, book ahead.

Coming without a car really is possible

You often hear it: “a ski resort without a car doesn’t exist.” In Oz, it does. The chain works well: train to Grenoble, then coach or shuttle to Alpe d’Huez or Bourg-d’Oisans, and finally gondola or connection to Oz. Once there, no more driving: Oz is a pedestrian resort-village where shops, ski school, equipment hire and lifts are all within walking distance — and the chalet only minutes away.

It’s even one of the arguments that weigh in when you hesitate between the two sides of the ski area, as we explain in our comparison of Oz-en-Oisans or Alpe d’Huez for skiing the Grand Domaine. The calm of a village, but the same giant mountain at the top of the lift. To go further on Oz’s atmosphere and services, our full review of the Oz-en-Oisans resort sets out what you can do on foot on site.

Our recommended arrival plan

Here, concretely, is how we suggest organising your journey to the chalet:

1. Choose your gateway. Car for flexibility in a group, train + shuttle to avoid driving, plane + Ben's Bus if you're coming from far away. Either way, the valley is reached via Bourg-d'Oisans.
2. Plan winter equipment ahead. 3PMSF tyres or chains from 1 November to 31 March — no exceptions. Practise fitting the chains before you set off.
3. Decide where to park. One car goes up to the village for the luggage; the others park for free at Allemond and ride up on the Eau d'Olle Express gondola.
4. Fix the arrival time with us. Avoid the Saturday midday peak, tell us your slot and the last shuttle: we arrange a smooth key handover.

Whichever option you choose, the idea is the same: limit the number of cars on the mountain road, travel light and arrive relaxed. With 16 under one roof, it’s this bit of planning upstream that makes the difference between a rushed arrival and a proper start to the holiday.
