The town of Farnborough in north Hampshire is probably best known for its biennial international airshow. Hundreds of companies exhibit at the show and thousands of people visit.
Farnborough forms, with Blackwater and Aldershot, a projection of northeast Hampshire into Surrey. The River Blackwater marks the county boundary. The town lies at the centre of the Blackwater Valley conurbation, which includes Aldershot, Camberley, Yateley, Sandhurst, Frimley and Farnham.
