One of Britain's principal canal junctions, Trent Lock's great meeting of waterways is also the border between the historic counties of Nottinghamshire, Leicestershire and Derbyshire.
Here, the River Soar and Erewash Canal link to the Trent and Mersey canal via the River Trent and its Cranfleet Cut. The River Soar forms the border between Leicestershire in the west and Nottinghamshire in the east, whilst the River Trent forms the Derbyshire border.
