If you are coming from the north, you can either take the Brenner motorway to Bolzano and continue on the MeBo (Meran-Bozen expressway) to Lagundo or via the Resio Pass and the Val Venosta state road to Töll. You can also drive from the south and east to Bolzano and continue via the MeBo to Lagundo. From the west, however, simply follow the Val Venosta state road.
