DRIVING IN THE AOSTA VALLEY
TOLL ROAD vs RTE SS 226:
At the toll booths, you either take a ticket or pay for the ticket you have. Watch for the Biglietta word/pictures to make sure you don’t end up in the “toll tag” or credit card only lines. The toll road from Nus to Aosta is about $15 each way, so we use SS226 almost all the time (unless we’re going straight to or from Mt. Blanc/Courmayeur).
From Marsan to Aosta: Go west on SS226 and watch for the direction “AOSTA/MT. BLANC”.
From Aosta to Marsan: Go east on SS226 and follow the signs to TORINO/MILAN. It won’t say Nus until the round-a-bout that has the Nus exit. Watch out: there’s one place where the right lane becomes an exit only for the Toll Road. If you get off there by accident, I think you can go around the circle and come back up onto SS226 – just watch your direction towards “Torino” if you’re going home to Marsan.
Parking in Aosta: When you go into Aosta, there are various parking options.
One option is to park in the large parking lot for the "Gondola to Pila" on the east side of Aosta just before you get to the town center and walk into town from that direction. Look for signs to Pila.
Another parking option is the pay parking lot on the south side of the town center of Aosta in Piazza Plouves: Go around the Roman Arch roundabout as you enter Aosta on the east side of town, go south (left) on Vialle Garibaldi, turn right on Via Torino and go about 4 blocks, the parking lot is on the north (right) side of the street just past Via Vevey. This parking lot puts you right at the Porta Praetoria where the Tourist Information office is.
Also, there is pay parking on the west side of the Aosta town center in the Piazza della Repubblica: continue on Via Torino past the Piazza Plouves for several short blocks then turn right on Vialle Partigiani and right into the Piazza della Repubblica. You then walk into the town center from the west end of town.
