Traveling by bus, taxi or train
The public transport service in the valley of Gressoney is assured by VITA company buses. The "SHUTTLE" in winter are always free, while on all the other busses, payment is made directly on board. The service is day and evening, so if you want to move at night, after 20:30 you have to call a taxi. We suggest to contact it in time as in Gressoney there is the only one.
