Dollis Brook runs through the London Borough of Barnet in North London. It is a tributary of the River Brent. The Dollis Valley Greenwalk follows almost all of Dollis Brook, apart from a short section at the beginning which passes through private land, and the London Loop follows it as far as Barnet Lane. The name Dollis is probably derived from the Middle English word 'dole', meaning the shares of land in the common field.
The Dollis rises on Moat Mount Open Space in Mill Hill. Its course is eastwards through Totteridge Fields, a Site of Metropolitan Importance, and then through fields and open spaces to King George V Playing Fields in Totteridge.
The Brook then turns southwards and forms the eastern boundary of Totteridge. It passes through Wyatts Farm Open Space and Brook Farm Open Space to Totteridge Lane near Totteridge and Whetstone tube station, and then continues south through Woodside Park (where it merges with the Folly Brook) and West Finchley, before passing under the Dollis Brook Viaduct which carries the Northern Line between Finchley Central and Mill Hill East tube stations.
Dollis Brook then passes under Dollis Road to the Great North Way (A1). Near Bridge Lane in Hendon it merges with Mutton Brook to form the River Brent.
Upper Dollis Brook is rich in aquatic plants, and kingfishers, grey wagtails, and moorhens can be seen along the stream. The lower part is less ecologically rich, but nevertheless forms a valuable green corridor through suburban areas.
