The stream runs, WNW then north, about 7 km (4.3 mi) in the Vale of Holmesdale (a mainly geological term explaining the axis of the basins of the Medway, Mole, Tillingbourne and Wey, west branch).

It mainly rises in the former manor farms and common land of Peaslake on the northern slopes of the Greensand Ridge.

It drains much of the northern Winterfold Forest/Hurtwood: the upper half of the drainage basin is forest with some pasture save for the large hamlet itself.

On the left bank the stream has, after its coalescence of headwaters, the northern lands of Farley Green (the secondary village in Albury parish) then briefly a low corner of Blackheath, Wonersh – a sparsely-inhabited wooded plateau, on the opposite bank of the closest-to-village fields of Albury's main settlement, including a further former millhouse.

[4] The North Downs Line follows a distant right bank of the Brook for 1.8 km (1.1 mi) along the width of Albury's essentially rectangular parish.
