Wimbledon Common consists mainly of a plateau of acidic grassland, the most notable area being The Plain.
Scarcely a crest breaks the smooth table and nowhere can you find a summit. Soils are impoverished gravels, ideal for heathland and bogs. The land falls away to the west down through the other main habitat, mature woodlands, to Beverley Brook, where the geology is predominantly London clay.
The golf course used by the two golf clubs is also a large feature of Wimbledon Common.
