It is very close to the present border with Surrey, and is not far from Ascot and Virginia Water. It is situated 24 miles (38 km) west of London and 7 miles (11 km) east of Camberley on the A30 national route. Sunningdale has a railway station on the Waterloo to Reading line.
The present-day civil parish of Sunningdale came into existence in 1894 under the provisions of the Local Government Act 1894; it had previously been part of Old Windsor. It was, until 1995, partly in Berkshire and partly in Surrey. The Surrey area of the village, known as Broomhall, and including the World-famous Sunningdale Golf Club, was also split between the boroughs of Surrey Heath and Runnymede. This original arrangement caused problems and was resolved only after much consultation locally between the two county councils, three borough councils and four parish councils.
