All people landing in Fiumicino or Ciampino can take a Gaspari or Flixbus direct bus to L’Aquila west side bus station (a.k.a. Amiternum or Hotel Amiternum). Timetable and route prices are available on their websites.
In order to get to LNGS independently from west side station (e.g. if shuttle bus timetable doesn't fit with your travel plans) the fastest and easiest option is to take a taxi cab (normally available at west side station, if needed call Radio-Taxi service: +39 0862 25165).
Participants may also take TUA-ARPA buses from Rome Tiburtina bus station to L’Aquila (timetable). First bus stop in L’Aquila is the same as Gaspari and Flixbus routes above (west side bus station, a.k.a. Amiternum).
In order to get to LNGS independently, people travelling on TUA-ARPA buses either can take a taxi cab from there (as above) or they can get off at Terminal Bus Collemaggio (final bus stop for TUA-ARPA bus routes) and then take a city bus to Assergi (line M6).
People travelling by car can take highway A24 from Rome and take the exit L'Aquila Ovest (1-hour drive trip approximately). West side bus station and some of the workshop-affiliated hotels are very close to this highway exit.
In order to reach LNGS by car, drivers can keep driving on A24 and take the exit Assergi: at the toll gate turn right and after 100 meters turn right again (via Giovanni Acitelli): drivers will find the laboratory gate on their left.
