The Grand Union Canal at its maximum extent included the Regent's Canal and so extended from Limehouse on the Thames up to the Midlands. There were two branches to Birmingham and to Leicester, the latter is nowadays known as the Old Grand Union Canal or the Leicester Section.
These days the Grand Union Canal (as commonly marked on maps or signs) starts at Paddington at the end of the Paddington Arm and extends up through London, Hertfordshire (the likes of Hemel Hempstead and Berkhamstead), Buckinghamshire (Aylesbury), Warwickshire (Leamington Spa and Hatton) and into Birmingham. The furthest extent is at Salford Junction underneath Spaghetti Junction. Both ends of the canal are in the centres of England's two biggest cities but the canal passes through some of the most beautiful countryside England can offer.
