Analysing terrain data
56 is the only way to ski directly from Zürs to Lech, it branches off 33 fairly low down and simply winds down along the valley between Zug and Lech.
Though not particularly exciting, this is a possible escape route for a skier who has lost their confidence half way down 33 and does not want to go to Zug, take another lift then ski all the way to Lech.
They can go straight into town along this path.
Though not recommended for its challenge or interesting skiing, run 56 is picturesque, and can be regarded as a tourist run, though not advisable for snowboarders as it is relatively flat.
