The river's headwaters rise at the foot of the scarp slope of the Dorset Downs near Buckland Newton and coalesce south of Pulham, from where the river flows north-east to it meeting with the Wonston Brook. Continuing in a northerly direction, the Lydden passes King’s Stag, to Twoford bridge where it is crossed by the A357 between Lydlinch and Bagber. Beyond this point t he river swallows its main tributary, the Caundle Brook.
