This is a list of routes on Sustrans's National Cycle Network within the United Kingdom.
As the cycle network has not been fully completed, some sections of routes are still under construction.
The National Cycle Network (NCN) was established to encourage cycling and walking throughout the United Kingdom, as well as for the purposes of bicycle touring. It was created by the charity Sustrans who were aided by a £42.5 million National Lottery grant. However Sustrans themselves only own around 2% of the paths on the network, these rest being made of existing public highways and rights of way, and permissive paths negotiated by Sustrans with private landowners, which Sustrans have then labelled as part of their network.
The Pennine Cycleway is a Sustrans-sponsored route in the Pennines range in northern England, an area often called the "backbone of England". The route passes through the counties of Derbyshire, West Yorkshire, Lancashire, North Yorkshire, Cumbria and Northumberland. It is part of the National Cycle Network (NCN). Sustrans founder John Grimshaw calls it 'the best National Cycle Network route of the lot'.
A greenway is usually a shared-use path along a strip of undeveloped land, in an urban or rural area, set aside for recreational use or environmental protection. Greenways are frequently created out of disused railways, canal towpaths, utility company rights of way, or derelict industrial land. Greenways can also be linear parks, and can serve as wildlife corridors. The path's surface may be paved and often serves multiple users: walkers, runners, bicyclists, skaters and hikers. A characteristic of greenways, as defined by the European Greenways Association, is "ease of passage": that is that they have "either low or zero gradient", so that they can be used by all "types of users, including mobility impaired people".
The Forth and Clyde canal pathway runs between the Firth of Forth and the Firth of Clyde and is a 106-kilometre-long (66 mi) footpath and cycleway that runs across Scotland, between Bowling, west of Glasgow, and Lochrin Basin in Edinburgh. The path runs on the towpaths of the Forth & Clyde and Union Canals and is entirely off road. The path is well maintained and its surface is generally good, although there are some stretches particularly between Falkirk and the outskirts of Edinburgh where wet weather leads to muddy conditions unsuitable for road intended bicycles. It is well used by walkers and cyclists, and designated as one of Scotland's Great Trails by NatureScot. It also forms part of the National Cycle Network, being designated as Route 754. Sustrans advises that the path is best followed from the Clyde to the Forth because the prevailing wind is from the south west. Much of the path is also suitable for experienced horseriders, although in some places low bridges, narrow aqueducts and gates may restrict access for horses.
National Cycle Route 4 is a route of the National Cycle Network, running from London to Fishguard, Pembrokeshire. Between these, the route runs through Reading, Bath, Bristol, Newport, Swansea and St David's. Within Wales, sections of the route follow branches of the Celtic Trail cycle route.
National Cycle Route 1 is a route of the National Cycle Network, running from Dover to Tain. The 1,264 mi-long (2,034-kilometre) cycle-path is located in the United Kingdom.
National Cycle Route 6 is a route of the National Cycle Network, running from London to the Lake District.
National Cycle Route 9 is a route of the National Cycle Network, running from Belfast to Dublin. It is the lowest-numbered route on the National Cycle Network outside of Great Britain.
National Cycle Route 78 runs from Campbeltown to Inverness. It was officially launched as the Caledonia Way in 2016 as part of the wider redevelopment of Scotland's cycle network. It runs from the Kintyre peninsula to the Great Glen and the route varies from on road to traffic-free forest trails and canal paths.
National Cycle Network (NCN) Route 66 is a Sustrans National Route that runs from Kingston upon Hull to Manchester via Beverley, York and Leeds.
The Dublin–Galway Greenway is a partially completed 'coast-to-coast' greenway and partial rail trail, in Ireland, funded by the Department of Transport, which is due to become the western section of EuroVelo EV2, a cycle route from Galway, Ireland, crossing Europe and ending in Moscow, Russia. The 276 km route was planned to be completed by 2020. It is due to be the fourth greenway in Ireland, after the Great Southern Trail, the Great Western Greenway and the Waterford Greenway.
The Royal Canal Greenway is a greenway, in Ireland, which will become part of the western section of EuroVelo EV2, and the Dublin-Galway Greenway. Since its official opening in March 2021, it is the longest greenway in Ireland. It spans from Maynooth County Kildare to Longford and Cloondara, County Longford passing through counties Meath and Westmeath.
The Devon Coast to Coast Cycle Route is a 99-mile waymarked route from Ilfracombe in north Devon to Plymouth in south Devon. It skirts the National Parks of both Exmoor and Dartmoor and incorporates part of the Tarka Trail in the north, The Granite Way from Okehampton to Lydford and Drake's Trail from Tavistock to Plymouth.
National Cycle Route 61 is part of the National Cycle Network managed by the charity Sustrans. It runs for 34 miles from Maidenhead (Berkshire) to Rye House (Hertfordshire) via Uxbridge, Watford, St Albans, Hatfield, Welwyn Garden City and Hertford in the United Kingdom.
Ireland's greenways are off-road routes for walkers, cyclists and other non-motorised transport in Ireland, which are often created as rail trails on abandoned sections of the Irish rail network. In the Republic of Ireland, several greenway initiatives have been centrally funded by the Irish government. In Northern Ireland, greenways are typically part of the collective British National Cycle Network (NCN).
National Cycle Network (NCN) Route 636 is a Sustrans Route that runs from Harrogate to Knaresborough. The route is 4 miles (6.4 km) in length and is fully open and signed in both directions.
