We highly recommend to use public transportation (Metro M1, stop EPFL) to come to the event as it is by far the best way to get around in Lausanne.
You can reach EPFL by public transportation from the Lausanne or Renens train stations.
See the Swiss Railway website for details and timetables.
From Lausanne train station (20 min), take the Metro M2 (direction Epalinges, Croisette), stop at Lausanne-Flon, change to the Metro M1 that will take you to the EPFL stop that is next to the SwissTech Convention Center.
From Renens train station (10 min), take the Metro M1 which starts in the train station next to Track 1. It will take you to the EPFL stop.
The SwissTech Convention Center is 10 minutes away from the highway exit “Lausanne Sud, UNIL-EPFL”. During the weekend (and weekend only!) your can park for free on green and white parking spots at EPFL.
Parking Rivier is one of the best options, just across the street from STCC. The Conference Center has its own underground paid parking lot: Parking les Arcades. If you want more information about parking, visit parking.epfl.ch.
