The walk is as the name implies a walk along the Chelmer and Blackwater Navigation which was created by the canalisation of the Rivers Chelmer and Blackwater in Essex. However, the walk does not follow the canal at all from the starting point at All Saints Church, Maldon. Firstly the walk heads away from the town of Maldon by crossing the River Chelmer and heading east to explore Heybridge Basin which provides excellent views of Northey Island. Only then is the route of the navigation followed for the whole length of it until its end in Chelmsford. Places encountered during the walk along the canal include Heybridge Creek, Langford Cut, Ulting Quarry (disused), Ulting Wick, Rushes Lock, Paper Mill Bridge, Little Baddow Lock (where a short detour to Little Baddow Hall is allowed), Sandford Mill Bridge, Chelmer Village and Barnes Lock before the finish at Chelmsford Cathedral.
