About Grand Union Canal

About Grand Union Canal

The main line of the Grand Union Canal is 220 km (137 mi), beginning on the tidal River Thames in London and ending in Birmingham, with 166 locks.

In the light of competition from railways and roads in the 19th and 20th centuries, several other canals were amalgamated with the main line to form what is now referred to collectively as the Grand Union Canal.

At 461 km (286.3 mi) in total, this is now by far the longest canal in the UK. This canal is part of the Warwickshire Ring, the Thames / Great Ring, the Leicestershire Ring and the Cotswolds Ring (as yet incomplete), allowing boaters to extend their journeys beyond this stretch of water.

Travelling along the main line alone will take boaters and walkers from the bustling heart of London, through the Chiltern Hills, rural Northamptonshire and Warwickshire, before terminating in the Birmingham suburbs.

There is huge potential for walking, cycling and exploring the history of the canal and wildlife across its entire reach.
