As it crosses the Aosta Valley, the Dora Baltea flows through the city of Aosta (where the Buthier runs into it) and then Saint-Vincent. After it enters Piedmont, it passes through the city of Ivrea and a good part of Canavese, reaching the Po at Crescentino, a little downstream from Chivasso.
It is a popular place for whitewater rafting and kayaking. Early in the summer, in May and June, the rivers are usually high with snow melt from the mountains. During July, August and September the water levels are usually lower and the temperature warmer.
