National Route 11 of the National Cycle Network will connect Harlow in Essex with Wigginhall St Germans (south of King's Lynn) in Norfolk via Cambridge and Ely. Harlow to Stanstead Mountfitchet and Waterbeach to Wicken are still under development, along with a link to Saffron Walden. The route is described here from Stanstead Mountfitchet to Wigginhall St Germans but is signed in both directions. Where no printed map is available for a particular section please use the Sustrans online mapping.
The route is open from Stansted Mountfitchet to Cambridge via Ickleton as far north as Waterbeach, and between Wicken Fen and Wigginhall St Germans. It is possible to stay on the National Cycle Network and avoid the gap in the route between Waterbeach and Wicken Fen by using a section of National Route 51 via Bottisham and Burwell.
Harlow to Cambridge
Aside from a standalone traffic-free section between Sawbridgeworth and Spellbrook, the route begins in Stanstead Mountfitchet and follows minor roads as far north as Whittlesford. From here the route is predominately traffic-free into south Cambridge, then following a combination of on-road and traffic-free sections into the city centre.
Cambridge to Wigginhall St Germans
National Route 11 follows the traffic-free Fen Rivers Way/ Hailing Way on the west side of the River Cam as far as Waterbeach but for a continuous NCN route follow National Route 51, which leaves Cambridge on the east side of the river and links back to Route 11 near Burwell. National Route 11 continues to Wigginhill St Germans (just south of King's Lynn) predominately on minor roads with a long section of traffic-free along the Fen Rivers Way between Barway and Ely.
