Toys Hill forms part of the 450 acres of woodland that lies between the towns of Westerham, Edenbridge and Sevenoaks and is a designated Site of Special Scientific Interest and a Grade I site of national importance for nature conservation. One reason for this is the National Trust’s Bat Tower – a disused water tower, built in 1906, that has been transformed into a hibernation site for bats. The area’s name derives from a local family who owned the land in the middle ages.
