The ESRF/ILL/EMBL/IBS site is easily reached by car using the motorway connections.
When coming from Geneva, Chambery or Turin on the A41 motorway, follow the signs for the "Rocade Sud/N87" (the Grenoble ringroad) direction "Lyon". This will take you on to the A480. Continue on the A480 in the direction of "Lyon".
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, heading north along the Rue des Martyrs (D531). The new site entrance is on the left after a few hundred metres (traffic lights).
Lyon International Airport, Saint Exupery Airport, is the most convenient airport to reach Grenoble. For more information, visit the Lyon Saint Exupery website (or phone +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". Buses run hourly, seven days a week (timetable).* People under 25 pay a reduced rate.
The bus will stop near the ESRF/ILL/EMBL site on request, so that you do not have to go as far as the bus station. Ask for the bus stop called 'Place de la Resistance' situated at the roundabout by the 'Pont d'Oxford' (suspension bridge) motorway exit (this is also the stop for local buses EXP 1 & EXP 2). You must tell the bus driver when boarding at the airport that you want to be dropped off at "Presqu'île - Résistance". Otherwise, despite it being an official stop, the driver may not stop! You are less than 10 minutes walk from the EPN Campus.
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 from where you got off.
* 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.
