The head of the valley is a bleak moorland, with hills around it exceeding 1,640 feet.
The River Balder enters Balderhead Reservoir about four miles from the source, at around 1,080 feet. It spills into two more reservoirs further down Baldersdale: Blackton Reservoir and Hury Reservoir.
The scenery becomes gentler as it descends past Baldersdale Youth Hostel. The distinctive flat peak of Goldsborough to the south is passed before the valley begins to open out as the river enters Blackton Reservoir at around 920 feet.
The course of the valley carries on at a virtually exactly east direction as the River Balder enters Hury Reservoir at about 850 feet, passing the village of Hury which lies to the north.
