Plan London Borough of Hillingdon

Editorial responsibility: Elena Voss · Roavina Travel Editor

Hillingdon, the westernmost London borough, encompasses outer London's western reaches and includes Heathrow Airport alongside rural areas and RAF Northolt Aerodrome. The Polish War Memorial, Battle of Britain Bunker, and Harmondsworth Great Barn stand among its historical sites. Nature reserves and country parks dominate the landscape, offering little of conventional tourist interest beyond these specific attractions.
