Some nationals require a visa for France. This is delivered as a Schengen visa. Note that if you are travelling from another Schengen country to France you will be permitted to enter France provided your visa is valid during the whole period of your stay.

A Schengen visa will allow you to enter Switzerland. Likewise Swiss authorities also issue Schengen visas. A valid Schengen visa allows to stay in both France and Switzerland.

If you require a visa, please indicate so when you register so that we can send you appropriate invitation letters. We also urge you to apply for visas at least two months in advance.

It is a good idea to download/print the leaflet (leaflet for session 1 / leaflet for session 2)  of the Centre with you especially if you are not taking the Conference bus. The map in the leaflet indicates the location of  the various buildings including the chalets you will be sleeping in. The room/chalet allocation will be available a few days before the start of the session as  a download through the wiki, make a note of your chalet and room number. You will  need the pin code to enter  the chalet. The list of pin codes will also be accessible   on the wiki (restricted access), make a note of the code for your chalet. We recommend that you save the pin code to your chalet in your phone contacts, together with the name of the Chalet and Room number.

By Conference Bus from/to CERN [recommended, details to be confirmed]

Only those who are registered to take the conference bus will be able to board the bus. 

In case of a problem on the day of departure or if you are late to take the conference bus, send an This email address is being protected from spambots. You need JavaScript enabled to view it.You may also call or send a SMS to the following (mobile) telephone numbers of one of the organisers who will on the bus: 

Session 1: **** : + ***

Session 2: ****: + *** 

One or two of the organisers will be at the meeting point at CERN. Make sure you are not late. The bus will not wait long.

Conference Bus: CERN <-> Les Houches (Centre de Physique). The bus journey from CERN to Les Houches takes about 1h40.

Departure from CERN: Monday 7 June 2021 at 16:00, Main Entrance B. [TBC]  

Departure from Les Houches: Wednesday 16 June 2021 at 13:30. 

Departure from CERN: Wednesday 16 June 2021 at 16:00, Main Entrance B. [TBC]

Departure from Les Houches: Friday 25 June 2021 at 13:30.

Once the bus arrives at the Centre we will distribute a (leaflet for session 1 / leaflet for session 2) that will indicate the location of  the room and chalet you will be sleeping in.

Note that on Wed 16 and Friday 25 the bus from Les Houches to CERN will first stop at Geneva Airport before continuing to CERN. This is not only very useful for those taking a plane but also those taking a train. If you have a train to catch on those days it is advisable to start your train journey from Geneva Airport rather than Cornavin (Geneva Main Train Station). You will save time not taking the bus/tram from CERN to Cornavin.

By Local Buses from Geneva

This is not recommended as the service is quite limited (2 departures a day only. Moreover the bus stops in the village in the valley which is 5 km way from the Centre!)

From Geneva centre (main bus station) to the Les Houches Village.

Take the bus going to Chamonix and get off at the stop Office du Tourisme (tourist centre) of Les Houches. Note that this bus starts from Geneva Airport before continuing to Geneva centre, and then to the Chamonix Valley (les Houches).
Bus Timetable: Geneva bus station website

Note however that this service is not convenient. First it is not frequent. Second, the bus stops in the village which is still 5 km away from the School. If you do not want to climb on foot, we advise you to take a  taxi from Les Houches village. Fare: about 15 Euros.
You need to reserve a taxi by calling one of these five companies (you may also ask This email address is being protected from spambots. You need JavaScript enabled to view it. to reserve the local taxi for you, but inform the secretariat  at least 4 days before the trip).

  • Cham Taxi: +33 6 07 26 36 62 (mobile) 
  • Taxi Carrier: +33 6 22 75 19 37 (mobile)
  • Taxi Plus: + 33 6 12 35 30 72 (mobile)

replace the first 0 with +33 for an international call

To go from Geneva train station to the bus station, see here.

For a map of Geneva and general information, go here.

Once you arrive at the School, go to the Secretariat in the Chalet Cécile DeWitt (previously Jacassière) or just look for your pigeon hole in the lobby. In the main building, there will be a  list indicating your room (Lodging Plan). You still need the pincode to enter the chalet. The pincodes will be on the wiki (restricted access). We will also send the list of pincodes by email a couple of days before the meeting. Bring the leaflet (leaflet for session 1 / leaflet for session 2), with you or save it on your phone.

Shuttle/Limo service from Geneva Airport

If you are not taking the Conferene bus, this is the most practical way to get to the Centre.

Geneva Airport is 1 hour drive from les Houches. There is a regular bus service between Geneva Centre and Les Houches (see section Local Buses from Geneva).

The simplest way is to use a shuttle service (approximately 40 euros up to the School, book at least three days in advance). If you already have your return date, we would recommend to book a return tripClick here for a complete view of the different companies. Beware: The Ecole des Houches does not recommend the Alpybus company since this company will only take you to the village des Houches which is 5 km away from the Centre. NB: You can have a discount with the company Mountain Drop-Offs: MDO discount. Mountain Drop-Offs transfer desk at Geneva Airport, here.

You could also rent a car from Geneva Airport.

By train

Arrival at Les Houches station is through at least one change at Saint-Gervais (from France) or at Martigny (from Switzerland). There are about 10 trains per day between St Gervais and Les Houches. If you are coming from Geneva we strongly advise you not to take the train too many changes. Les Houches train station is about 5 km from the Centre de Physique (the latter being uphill!!). If you do not want to climb on foot, we advise you to take a taxi. See tips on taxi in the above section on "Local Buses from Geneva".

For other fares, updated train timetables and reservations, you can consult the French Railways site.

By car

The best way to find your way (if you don't have a GPS or a mobile phone with a data plan) is to print the itinerary given by the online Michelin interactive map or of course google maps

Les Houches are easily accessible from France (A41 highway), from Switzerland (Martigny and Col des Montets).

From Geneva and Le Fayet: 8 km before Chamonix, 300 m after passing under a tunnel, bear right by the first road out for "Les Houches Les Trabets".  

When arriving at the cable car station "Bellevue", turn right and continue upwards (roughly 2 km starting from the cable car).  You will reach a small roundabout, near a second cable car station, named the "Prarion". Turn left and follow the sign "Ecole de Physique". Go uphill  till the Route de la Côte des Chavants where you will have to make a sharp (right) turn (there is a sign for Ecole des Houches/Centre de Physique).  You should then drive almost all the way up the Côte des Chavants and follow Parking Visiteurs. 

From Chamonix: bear right for "Les Houches-Chef-Lieu", turn right in Les Houches, go ahead at the cable car station "Bellevue". Then proceed as above.

Cars may be rented from Geneva and from Chamonix, but it is useful to make a reservation well in advance.

Once you arrive in the Centre, please park your car in the "visitors' car park" then walk down (or take the stairs) to the main buiding. Bring the leaflet with you (leaflet for session 1 / leaflet for session 2) with you. The Secretariat is in the Main Building (Cécile DeWitt). You can also just look for your pigeonhole in the lobby the Main Building. There will be a  list indicating your room.
