Park the car on the junction of Norfolk Rd, Wharf Rd and Mark Lane and just walk alongside the canal, with the rail tracks on the other side. There is very little traffic. The road turns into a cycle path. It smells sometimes as you pass the sewage works but that doesn’t last long. You can also walk down the road where the paddocks start and before the rifle range. This leads you to the Thames and you can walk for miles along the bank. I really like the industrial feel of this walk even though it leads into the marshes.
