According to legend, Mad Bess Wood owes its name to the wife of an 18th century gamekeeper, a demented old woman who prowled the woods at night looking for poachers.
Most of the site is wooded, with extensive areas of hornbeam coppice and common or sessile oak. The remaining woods contain oak, birch, aspen, beech and sweet chestnut.
The reserve is part of Ruislip Common. The A4180 bisects the reserve from north to south with Mad Bess Wood and Bayhurst Wood to the west of the road. Park Wood and Copse Wood are to the east of the road on either side of the Ruislip Lido, a former reservoir.
