The Beam Valley divides the London Boroughs of Barking & Dagenham and Havering, and forms part of the Dagenham Corridor, a valuable green corridor that extends all the way through eastern London from rural Essex to the Thames. This is designated as Green Belt and much of it is now publicly accessible and managed for wildlife.
Access from Dagenham Road which runs south from Rush Green Road (A124 Upminster–Hornchurch–Dagenham). Turn off left just before the Farmhouse Tavern.
District line tube to Dagenham Heathway and then bus 174 to Rush Green; or 15-minute walk from Dagenham East station via the footpath alongside the chemical plant.
