We have arrived. Here, where the street ends on a sunny slope high above Val Müstair, lies the small village of Lü. This wonderfully secluded settlement is utterly dark at night, so it’s also an ideal location for star gazing. The four kilometre sled run starts here, right next the PostBus stop, and takes us through snow-covered forests all the way down to Tschierv. Every Tuesday and Thursday evening, the Schlittel Express transports sledding enthusiasts to the start of the illuminated sled run.
