Out the front of NLC and directly across the road.
Follow Chalk Road and then Chadwin Road as far as New Barn Street. Carefully cross the road and take the small road just to the left and then turn right along Carson Road, taking the third street on the left, Cambus Road, which then becomes Newhaven Lane.
At Barking Road cross over and continue along the western side of Newhaven Lane, which then becomes Star Lane. Cut through Star Lane park if open else continue until Manor Road. Cross over the road by using the Star Lane DLR footbridge, picking up Cody Road the other side. Follow this as it becomes Twelvetrees Crescent though the industrial estate, crossing over the mini roundabout and continuing straight on and over the bridge, exiting at the Blackwall Tunnel Northern Approach road.
Turn left and then left again into Bow Locks. Take the duckboard pontoon bridge under the road to emerge onto the Limehouse Cut towpath.
Follow the towpath all the way down as far as Burdett Road.
At this point, turn around and retrace the route back to NLC.
