Here, just inside Hertfordshire, the Walk soon leaves the old railway to go up to a viewpoint over Wheathampstead, which has a unique church spire rising above a church little changed for 650 years. The next landmark is Brocket Park’s mansion and lake. Beyond the riverside village of Lemsford comes the modern Stanborough Park with its massive man-made lakes fashioned for the residents of Welwyn Garden City. But on the edge of Hatfield the Lea still turns a working flour mill.
