The woods include one of the most extensive oak/hornbeam coppice woods in southeast England, and also acid and neutral grassland, ponds, streams and marshland. The nature reserve itself comprises four woods: Park Wood, Copse Wood, Mad Bess Wood and Bayhurst Wood. There is also a lido nearby, for the summer months.
The nature reserve is accessible via Ruislip tube station, which is on the Uxbridge branch of both the Metropolitan and Piccadilly lines. The H13 and the 331 bus routes stop close by. For more information, visit http://www.hillingdon.gov.uk/index.jsp?articleid=13149.
