It is immediately northwest of London Gatwick Airport in West Sussex, close west of Horley and north of Crawley. The historic county boundary between Surrey and Sussex ran to the south of Gatwick Airport. Boundaries were reformed in 1974 so that the county boundary between Surrey and West Sussex, delineated by the Sussex Border Path, now runs along the northern perimeter of the airport, and the southern extent of Charlwood.
