The North Downs are a ridge of chalk hills in south east England that stretch from Farnham in Surrey to the White Cliffs of Dover in Kent.^[1] Much of the North Downs comprises two Areas of Outstanding Natural Beauty (AONBs): the Surrey Hills and the Kent Downs. The North Downs Way National Trail runs along the North Downs from Farnham to Dover.

The highest point in the North Downs is Botley Hill, Surrey (270 m (890 ft) above sea level). The County Top of Kent is Betsom's Hill (251 m (823 ft) above sea level), which is less than 1 km from Westerham Heights, Bromley, the highest point in Greater London at an elevation of 245 m (804 ft).
