Follow the trafic signs from Chur to Arosa. Turn right at the entrance of the village when you reach the petrol station and follow the road to Prätschli.
As there is only a limited number of parking lots available at Prätschli, we recommend you to park your car at the parking garage Ochsenbühl. There is a bus stopp only few metres away.
