Tan Hill, Wiltshire

Tan Hill (grid reference SU080640) is a hill which lies just to the north of the village of Allington in the parish of All Cannings, Wiltshire, England.

Its summit is 294 metres (965 ft) above sea level and is the second highest point of the North Wessex Downs AONB hill range (the adjacent Milk Hill is 295 m high) and of Wiltshire. It is also the third highest point between Bristol and London. To the south, its adjoins Clifford's Hill.

On 23 August 2009, the BBC programme Countryfile featured an item on analysis by Ordnance Survey to determine whether Milk or Tan Hill is the highest. It was confirmed that Milk Hill is 26 centimetres (10.2 in) higher than Tan Hill.

Along the north side of Tan Hill runs a section of The Wansdyke, an earth rampart which runs east to west across much of southern England.

Tan Hill formerly had a white horse.

In April 2003, a Dotterel was present on the summit of Tan Hill. This bird species does not usually migrate through Britain until May.
