Marsworth Lock Flight - Grand Union Canal.
The area around the 9 locks which make up Marsworth Lock Flight is very popular with visitors - there are
many excellent walks
both short and long which you can do around the area including a wander out into the Bucks countryside along part of the
narrow Aylesbury Canal Arm
which leaves the Grand Union near to Bridge 131.
The Aylesbury Arm is controlled by a fairly rare feature i.e. a staircase lock.
This is where the upper gate of one lock also serves as the lower gate of the lock above it.
The Aylesbury Arm was at one time planned to continue on to Abingdon and ultimately create a link with the Kennet and Avon Canal
so that a canal route from Bristol to The Grand Union and London and the Midlands would be possible. Another excellent walk in the area is along part of the really
beautiful Wendover Canal Arm
which leaves the Grand Union Canal via a nice bridge at Bulbourne Junction.
