After passing through Frederiksdal Storskov, the river runs under Nybrovej until it runs into the lake of Lyngby Sø. Between here and the sea, the river falls a further {{convert|20|m|abbr=on}}, providing excellent opportunities for water mills. The river winds through the gardens of [[Sorgenfri Palace]] to Fuglevad water mill which later became part of the [[Brede Works|Brede Copper Works]]. The river then continues to the north past the Frilandsmuseum and on to [[Brede Works|Brede Museum]]. It then proceeds past Øhrholm and Ravneholm to Nymølle, used to hammer copper and brass from the mid-17th century. It then flows under the [[European route E47|Helsingør Motorway]] to Stampen where priviously a textile factory, a flour mill and a bakery used to exist. After passing through [[Raadvad]], the Mølleåen finally arrives at Strandmøllen before reaching the Øresund.<ref name=ts/>
