4.5 miles (7km)This stretch takes the Walk past Waltham Abbey where the Norman church divides the market town from the rich watermeadows. The river here was first improved for navigation in the late 12th century by the Abbot. Further south the route passes into Greater London. Ponders End does not have a Sunday train service but a new bridge at Mossop’s Creek provides a route to Brimsdown Station where trains stop at least hourly.RefreshmentsCheshunt: Tea Room at YHA Lee Valley Village.
