Box Hill is a summit of the North Downs in Surrey, approximately 31 km (19 mi) south-west of London. The hill gets its name from the ancient box woodland found on the steepest west-facing chalk slopes overlooking the River Mole. The western part of the hill is owned and managed by the National Trust, whilst the village of Box Hill lies on higher ground to the east. The highest point is Betchworth Clump at 224 m (735 ft) above OD, although the Salomons Memorial overlooking the town of Dorking is the most popular viewpoint.

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. 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.
