We are hosted in several buildings situated on the east side of the university campus. The main building, called "OSUG A" is where the Odyssey, Exoplanètes, Sherpas teams and the salle Manuel Forestini are located. It is at 414 rue de la piscine. The Planéto and Interstellaire teams together with part of the lab administration are in the "OSUG-PhiTEM D" building at 122 rue de la piscine.

Coming by train, tram

The Grenoble train station is served by direct TGVs (fast train) from Paris (and St-Exupéry airport). To get to IPAG, the easiest is to take a tram. Tram B is direct from the train station to the campus in about 20mn. You can buy a ticket at one of the automatic machines, validate before boarding the tram (ticket valid 1 hour), and board tram B going to Gières-Plaine des Sports. The stop on the right when exiting the train station. The nearest stop to IPAG is Les Taillées. Once there, cross the tram lines and walk north 200m to get to 414 rue de la piscine (OSUG A). The OSUG-PhiTEM D building is closer to the tram B stop : cross the tram lines and take the first right. See map below.

Coming by plane

The Lyon-St Exupéry airport is the most convenient international airport to get to Grenoble. Very frequent buses run between the airport and the bus station, located downtown right next to the train station (timetable). It takes 1h05 to get to/from the airport, located about 100 km away. Tickets can be bought online or at the bus station. Another option is the Geneva airport, also accessible by bus from the station in about 2h15 (timetable). Finally, the Grenoble airport caters mostly to low cost airlines bringing in skiers during the winter. Located about 50 km from Grenoble, it is accessible by coach in 45mn (more info).

By car

If you come from Lyon (A48 motorway) or from Gap/Sisteron (N175/N185), follow the signs for "Chambéry, Rocade Sud". If you come from Chambéry (A41 motorway), follow the signs "Lyon, Valence, Rocade Sud". To reach IPAG, take exit 2 of “Rocade Sud” (named “Saint Martin d’Hères-Péri”), and follow the signs to “Saint Martin d’Hères, Avenue Gabriel Péri”. Follow avenue Gabriel Péri and turn right at the crossing with avenue du Doyen Louis Weil (supermarket Géant Casino on your left). Turn left at the first roundabout, then cross the tram railways (rue de la piscine). OSUG-PHITEM D building is right after the railways to your right (number 124). Drive for 200m on "rue de la piscine" to reach OSUG A building (number 414). There is a car park behind the building.
