So is this the ancient Weald Stone? Ultimately, we cannot be 100% certain that the lump of rock outside Bombay Central (the former Red Lion) is the same stone that gave Wealdstone its name. However, its location on the High Road matches up persuasively with the Tudor rolls. A 1948 study by the London and Middlesex Archaeological Society puts the connection "beyond all reasonable doubt". That's good enough for me. Despite the recognition by Historic England as a Grade II-listed "building", the stone sits on the pavement without any form of plaque or interpretation board. That's a pity, but it also adds to the enigma of this curious piece of stone.

The ancient woodland here is the largest in Greater London. It feels like a real forest, yet within the city. It is quiet and calm, even when the lido is busy on hot summer days. There is a cafe at the lido for refreshment before, during or after your hike.

Chipperfield Common is a 117-acre (47 ha) area of former heathland that has developed into beautiful woodland since grazing stopped here in the 1930s. There are a quintet of ponds on the common, as well as eight ancient sweet chestnut trees. Evidence of a Neolithic history can be seen in the form of two Bronze Age burial mounds.

Wood Farm was opened to the public in 2015 and has been a working farm until the end of the 20th century. The farm buildings disappeared, only the Old Dairy still exists and is now a visitor centre. The viewpoint has a wide panoramic view from Alexandra Palace in the east to Heathrow in the southwest, and over London to Box Hill in the south (on a clear day that is). There is also a bathing pond on the way to the viewpoint.
