NCR 6

National Cycle Route 6 (or NCR 6) is a route of the National Cycle Network, running from London to the Lake District.

Parts of the route are currently incomplete and some sections follow other routes.

The proposed route is to begin in central London, running from Charing Cross via Paddington railway station to the Grand Union Canal. The towpath alongside the canal between Paddington and Northolt is already designated as a local cycle path, and will eventually form part of Route 6 when the route is completed. The canal continues to Uxbridge where the National Cycle Route 6 joins National Cycle Route 61 at Cowley, near Brunel University, sharing the same path until the two routes diverge at St Albans. The route continues along the Grand Union Canal and the Colne Valley on mainly traffic-free routes. At Rickmansworth it joins the Ebury Way, a rail trail which runs along a former line of the Watford and Rickmansworth Railway. Entering central Watford, the route continues north via St Albans with some on-road sections to Harpenden, where it intersects with National Cycle Route 57 and the Chiltern Cycleway. It then progresses along the River Lea via Luton, along the Sewell Greenway before joining the road network to reach Leighton Buzzard. At this point is re-joins the Grand Union Canal (Grand Junction Branch) to reach Bletchley, and then continues on mostly traffic-free paths to Milton Keynes.
