Overview
The TER 43 links Annecy to Saint-Gervais-Les-Bains, cutting through some of the finest mountain and lake scenery in the region on a regional train ticket rather than a premium fare. It is not a glamour service with a special name or dedicated carriages — it is a workhorse regional line that happens to run through territory dramatic enough to make you forget you are on public transport.
This is a journey for people who want the scenery without the fuss: no need to reserve a specific seat months ahead, no complicated fare structure to decipher, just a straightforward regional train that trades speed for a front-row view of the landscape as it climbs from the lake towards the high mountains.
What follows is a practical guide to riding it well — where to sit, what to expect on board, when to go, and how to plan around it using the operator's own timetable rather than guesswork.

The route: lake to mountains
The train begins in Annecy, a town built around its lake, and finishes in Saint-Gervais-Les-Bains, a settlement in the high mountains close to the base of the wider Alpine massif. Between the two, the landscape changes character steadily: you leave the open water and gentler valley floor behind and move into narrower, steeper terrain as the line climbs.
The journey has a real sense of progression rather than a single dramatic reveal — it is less about one postcard moment and more about watching the scenery tighten and rise around you, field by field and ridge by ridge, until the mountains properly close in near the end of the line.
Timetable and how to book
Services on this line vary according to the time of year, with different patterns operating in peak holiday periods compared with quieter months. Because of this, there is no single fixed schedule worth memorising — the only reliable approach is to check current departures directly with SNCF Voyageurs, who operate the service as part of the regional TER Auvergne-Rhône-Alpes network.
Booking a regional service like this is normally simple and flexible compared with long-distance trains, but exact conditions, advance-purchase options and any seasonal changes should always be confirmed with the operator before you travel, especially if you are travelling at a busy time of year or connecting onward to a specific onward departure.
Fares and classes
As a regional TER service, this train generally offers a simpler fare and class structure than the long-distance network — think of it as functional rather than luxurious, with the emphasis on getting you there comfortably rather than on frills. Where a higher class of travel is available, the practical difference tends to be in seating comfort and a slightly quieter, less crowded carriage, rather than in separate catering or exclusive facilities.
Whatever class you travel in, the main draw here is the view through the window, which is available to everyone on board regardless of ticket type. For exact fare levels, discount cards, or any class options currently offered on this route, check directly with SNCF Voyageurs, since these details can change and are not worth guessing at.
Which side to sit for the best views
Because the line moves between open lake-adjacent terrain and increasingly enclosed mountain valleys, the more rewarding side of the train can shift over the course of the journey rather than staying constant from end to end. As a general rule, it is worth choosing a seat away from the aisle so you have an unobstructed view, and being ready to look both left and right as the train changes direction relative to the valley.
If you are unsure which side will suit the outward or return leg better, ask staff at the station or on board — on a line with this much scenic variety, being flexible about where you sit matters more than picking one fixed side and staying loyal to it for the whole trip.
Onboard experience
Expect the standard, honest feel of a regional train built for a scenic mountain line: wide windows that make the most of the surrounding terrain, and a layout designed for practicality rather than spectacle. There is no suggestion here of a dedicated panoramic observation carriage or a full dining service — this is a regional train, and it should be enjoyed as one.
The pleasure of the journey comes largely from simply sitting back and watching the landscape do the work, rather than from onboard entertainment or catering. If you want refreshments for the trip, it is sensible to bring your own, since facilities on a regional service like this should not be assumed and are best confirmed with the operator if catering matters to your plans.
Best season to travel
This region changes dramatically across the year, and the train ride changes with it. In the warmer months, the lake at the Annecy end is at its most inviting and the mountains beyond are green and accessible, making it a strong time for travellers who want to combine the train journey with walking or general exploring at the Saint-Gervais-Les-Bains end.
In winter, the same route takes on a different character entirely, with snow transforming the higher parts of the landscape and the mountain terminus becoming a natural point of arrival for anyone heading into the snow season. Each season has its own appeal, so the right time to travel depends more on what you want to do at either end of the line than on any single best moment on the calendar.
Alternatives and onward connections
Saint-Gervais-Les-Bains sits at the edge of high mountain country, and for many travellers the train is only the first leg of a longer trip further into the mountains by bus, cable car, or other local transport. It is worth planning any onward connection in advance, since options and frequency can vary by season in the same way the train timetable does.
If the train does not suit your schedule, regional buses may offer an alternative way to cover all or part of the route, though these will have their own timetable and character. As ever, the operator is the right source for up-to-date information on how this line connects with other public transport at either end.
A little context
Regional lines of this kind grew up to connect lake towns and valley communities with the high mountain settlements that had previously depended on road access alone, opening up the mountains to visitors travelling by rail rather than solely by car or coach. Over time, operation of these services has passed into the modern regional network run by SNCF Voyageurs under the TER Auvergne-Rhône-Alpes banner, which now manages the line as part of a wider set of regional connections across the area.
The result today is a working regional train that still does the job it always did — linking lake and mountain communities — while incidentally offering one of the more scenic regional rides available in this part of the country.
Common questions
- Do I need to book a seat in advance?
- Regional services like this one are generally flexible, but you should check with SNCF Voyageurs for current booking conditions, especially in busier seasons.

- Is there food or drink on board?
- Treat this as a regional train without guaranteed catering. Bring your own refreshments to be safe, and check with the operator if onboard facilities are important to your journey.
- What's the best time of year to ride this route?
- It depends what you want at the mountain end: warmer months suit lake and valley exploring, while winter suits travellers heading into the snow season near Saint-Gervais-Les-Bains.
- How do I get further into the mountains after arriving?
- Onward travel by bus, cable car or other local transport is common from Saint-Gervais-Les-Bains. Check current connections and timetables with the relevant operators before you travel.
