Travelling to the EPN Science Campus


The ESRF/ILL/EMBL/IBS site can be easily reached by car using the motorway connections.

When coming from Geneva, Chambery or Turin on the A41 motorway, take the "Rocade Sud" (the ringroad, direction "Lyon") which takes you onto the N87 and subsequently the A480.
Leave the Rocade Sud at exit N°1 (i.e. of the A480) for the"Polygone Scientifique". At the first roundabout turn right. The entrance to the site will be on your right in a few hundred yards.

When coming from Lyon or Valence, stay on the A48 when approaching Grenoble, following signs for "Grenoble Bastille-Gares-Europole". Leave the A48 at exit N°16 ("Polygone Scientifique") and cross the suspension bridge over the Isère. At the end of the bridge filter right and turn right. The entrance to the site is on the left in a few hundred yards.




Satobus busstop map

Lyon's International Airport, Saint Exupery Airport, is the most convenient airport to reach Grenoble. For more information, visit the Lyon Saint Exupery website (or telephone +33 (0)4 72225000). Lyon Saint Exupery Airport is a one-hour drive from Grenoble and regular shuttle buses ('Navette Aéroport') operate to and from Grenoble bus station (‘Gare Routière’), which is next to Grenoble railway station. The shuttle bus is operated by "Faure Vercors" and buses run hourly (timetable).

The 'Satobus' shuttle will stop near the ESRF/ILL/EMBL site on request, so that you do not have to go as far as the bus station. Use the bus stops called 'Place de la Resistance' and marked 'Satobus' situated close to the roundabout at the 'Pont d'Oxford' (suspension bridge) motorway exit (these are also stops for the n°30 and n°715 local buses). You must tell the bus driver when boarding at the airport that you want to be dropped off at "Place de la Resistance". Otherwise, despite it being an official stop, the driver may not stop!

On your way back to the airport, be sure to use the bus stop near the roundabout on the 'Pont d'Oxford' side of the road and not the bus stop in front of the CNRS entrance also called 'Place de la Resistance' (see map).


Geneva International Airport is more than a two-hour drive from Grenoble. Bus and train connections to Grenoble exist but are not very frequent. Visit the website of Geneva International Airport for more details (or telephone +41 22 7177111).

A shuttle bus service runs between Geneva International Airport and Grenoble coach station: http://www.aerocar.fr/. Busses run 5 times a day (timetable and prices).


There is also a regional airport at St Geoirs (Grenoble Isère Airport, 40 minutes from Grenoble) that offers one flight a day to/from London's Stansted airport during the winter period (EasyJet). A bus from Grenoble St. Geoirs Airport to Grenoble is provided after every plane landing and stops at Grenoble bus station. The return bus from Grenoble leaves approximately 2h30 minutes before the departure time of each flight. This information is subject to change, please check the Grenoble Isère Airport website for precise times.

Shuttle services to airports

Scientists getting to the EPN site and back rely on the bus service between Lyon International Airport and Grenoble, that runs every hour, seven days a week. Departures (and arrivals) are possible either from Grenoble coach station, or from "Place de la Résistance" (next to the Pont d'Oxford), less than 10 minutes walk from the EPN Campus.

* Early morning buses from Grenoble (from 4 am) and late night buses from Lyon airport (last departure is 0.30 a.m) are available with prior reservation (72 hours in advance).

* Extra buses are scheduled during peak periods (every 30 minutes) is demand is sufficient.

Bus connections from Grenoble railway station to the "POLYGONE SCIENTIFIQUE".

There are two buses (TAG) you can take from the city centre to the site. For both bus routes, the journey takes approximately 10 minutes. There is a bus every 10-15 minutes throughout the day until about 8pm, the exact times depend on the period of the year so check the timetable at the bus stop. Tickets can be purchased singly from the bus driver or as a booklet ('carnet') at tobacconists and major tram stops.
