It is contained within the counties of Cheshire, Derbyshire, Greater Manchester, Lancashire, and Merseyside.
Essentially, the function of the belt is to prevent the cities, towns and villages in the large Greater Manchester and Merseyside conurbations from merging.
[2] The main coverage of the belt is within northern Cheshire and southern Lancashire, with the Merseyside and Greater Manchester urban areas completely surrounded, and a small section extending into Derbyshire.
The High Peak towns of Derbyshire, Glossop, New Mills, Hadfield, Charlesworth and Whaley Bridge are all enveloped.
A distant tract of belt also separates Lancaster and Morecambe from Carnforth, Bolton le Sands, Nether Kellet and Hest Bank.
