The park had been landscaped in the 18th century by Capability Brown when the lake was formed by constructing a dam across a brook that flows from the springline near Wimbledon Common down to the River Wandle in Earlsfield.

Along the park's northern edge lies Horse Close wood, a small patch of old planted woodland, largely consisting of Ash and Oak.

A Balcony is situated near the entrance at Home Park Road that once served as a tea room before the Second World War.

After its closure and abandonment, its windows got vandalised and was boarded up, as showcased in Raymond Briggs's story of his parents who once lived in the area, Ethel and Ernest.

Every November a large fireworks display takes place in Wimbledon Park, organised by Merton Council it is one of the largest and most popular shows in London.
