Getting in from the airport
Most visitors fly into Lyon-Saint-Exupéry, about an hour away: direct coaches run up to hourly from early morning to late evening to Grenoble's bus station beside the train station. Grenoble Alpes-Isère airport, out at Saint-Étienne-de-Saint-Geoirs, handles mostly winter ski flights, and in ski season a direct shuttle links it to the bus station (gare routière) in front of Grenoble's railway station. The timetable is built around flight arrivals, the ride has no stops in between, and it takes about 40 minutes. Book online if you can; if not, tickets are sold at the Grenoble bus station and by the driver, and if a flight lands late or you miss a departure, your ticket works on the next shuttle that day. The railway station sits at the edge of the center, and the bus station in front of it is where regional coaches and the city network connect, so onward trips start from the same spot.
