The road up to Arosa from Chur/Coira (595m) is long! It starts rather steep up from Chur and there is no water until far up the valley. The road becomes flatter and even dips here and there after Maladers and more so after Castiel. At St. Peter (1259m) there is a grocery shop. Here one could arrive via the road from Passugg (738m) and Tschiertschen (1345m) via Molinis (1040m) if coming from Lenzerheidepass/Parpaner Höhe (1550m). At Langwies (1373m) is perhaps the only good place for filling up the water bottle along the road. After Langwies it starts to climb steeper again, but then there is a 50m descent before the climb continues steeper still on the other side of the valley.

When arriving at the first big hotels there is an obvious big road going off to the right which you should follow. One passes by a golfing area and here it gets confusing, but you should really just stay on the asphalt road which is flat up here for a while. Then it becomes a little nicer on a smaller road, which could be filled with walkers. The asphalt ends just before the pass at Mittler Hütte (2010m) from where the gravel road continues for 180m to the pass.
