Car
We recommend taking the route below as it is the most relaxed to drive. Be aware that the roads in France require toll and you need a highway vignet for Switzerland (you can buy this at the border or online).
Airplane
Take the airplane from Schiphol to either Turin or Milan Malpensa.
Milan Malpensa is 2 hours drive from Aosta.
Turin is 1.5 hours drive from Aosta, but the flights are a little bit more expensive.
From both airports you can rent a car to drive to Aosta. You can take public transport, but we would not recommend this, as there are not a lot of options in Aosta.
If you want to be really green
We do not recommend this, but it is possible to take public transport to Aosta, see route below.
