Torino Caselle Airport
Turin Airport is 115 km from Aosta. If you decide to hire a car, reaching Aosta will not be a problem: all you have to do is follow the signs to the Turin motorway ring-roads (tangenziali), take the Regina Margherita exit and go onto the A5 motorway to Aosta. The journey should take you just over an hour. A train service links Caselle Airport directly with Turin's Dora GTT Station. Departures every half hour. Journey time: 19 minutes.
To provide users of Turin Airport with a better service, the airport station has been built right next to the terminal. From Torino Dora Station you have to go to Torino Porta Susa Station where you can catch the trains to Aosta. The city of Turin is also connected to Caselle Airport by regular bus services which leave every 30 minutes in the rush hours and every 45 minutes at other times (31 services a day each way).
