Overview
National Cycleway 99 forms a vital coastal corridor in the emerging National Cycle Network, linking the port town of Bangor to the seaside resort of Newcastle. Spanning 68.9 km, the route follows a mix of quiet coastal roads, historic town centres and scenic stretches along the Ards Peninsula and Strangford Lough. While the majority of the route requires cyclists to share the road with light traffic, it is clearly waymarked with yellow-on-black arrow signage and integrates seamlessly with traffic-free infrastructure like the Comber Greenway, making it accessible to confident riders and well-planned family outings alike.
The cycleway is free to use and open year-round. It serves as both a practical commuter link and a touring route, allowing visitors to experience County Down’s maritime heritage, protected wildlife zones and historic settlements without the need for a car. Because the route follows established roadways, cyclists have easy access to cafes, bike repair shops and public transport hubs at regular intervals.
Route Highlights
The journey begins in Bangor, where the route picks up near the harbour and Victoria Park. From here, the road sweeps south-west along the Ards Peninsula, offering uninterrupted views of the Irish Sea. The coastline here is dotted with small fishing harbours and coastal parks, making it an ideal stretch for photography and short walking breaks.
As the route approaches Portaferry, cyclists encounter the eastern shore of Strangford Lough. The ferry terminal here provides a practical connection across the water, and the surrounding area is recognised for its rich birdlife and marine habitats. Continuing along the western bank, the road traces the dramatic, winding shoreline of the lough before heading inland towards Downpatrick.
Downpatrick serves as a natural halfway point. The route passes through the town centre, where riders can pause at the historic cathedral and the Saint Patrick Centre. The town’s compact layout makes it easy to explore on foot, with several independent shops and traditional pubs offering a welcome rest stop. From Downpatrick, the cycleway resumes its coastal trajectory, heading south through quiet countryside and small villages before reaching the dune systems and sandy beaches of Newcastle.
Practical Information
National Cycleway 99 operates as a public road network, meaning there are no admission fees or restricted opening times. Riders should expect a predominantly on-road experience, with well-maintained tarmac and standard road markings. Traffic levels are generally low outside of peak summer weekends, but cyclists should remain alert at junctions and when passing through town centres.
Cycling Conditions
- Surface: Paved asphalt throughout, with occasional minor surface wear on rural stretches. Standard road or hybrid bikes are recommended.
- Waymarking: The route is signed with yellow-on-black NCN arrow markers. Look for supplementary directional signs at key junctions.
- Traffic-free connections: Cyclists arriving from Belfast can use the Comber Greenway to reach the southern edge of Bangor before joining the on-road section of Cycleway 99.
- Bike servicing: Independent cycle shops operate in Bangor, Downpatrick and Newcastle. Most stock puncture repair kits, and several cafes along the route carry basic tools.
Getting There & Around
The route integrates well with Northern Ireland’s public transport network, making it easy to drop off a car at either terminus and cycle one-way.
- Belfast to Bangor: NI Railways operates frequent services from Belfast Central to Bangor station, with the journey taking approximately 15 minutes. Ulsterbus route 202 also provides a direct road link.
- Bangor to Downpatrick: Goldliner and Ulsterbus services run hourly on weekdays, with reduced frequency at weekends. Bicycles can be carried on most services, though advance booking is recommended during peak periods.
- Downpatrick to Newcastle: Ulsterbus route 37 connects the two towns directly. The Goldliner 520 also offers a through-service from Belfast to Newcastle via the A2.
- Strangford Lough Ferry: The Portaferry ferry operates seasonally and carries cyclists free of charge. Timetables vary by time of year, so checking the operator’s schedule before departure is advised.
Tips for Cyclists
- Plan for on-road riding: This is not a fully segregated greenway. Riders should be comfortable navigating junctions, roundabouts and light traffic. High-visibility clothing and reliable lights are essential, especially in coastal conditions where fog can roll in quickly.
- Weather preparedness: County Down’s exposed coastline means conditions can change rapidly. Pack a waterproof layer and consider a lightweight windbreaker, even in summer.
- Dog policy: Leashed dogs are welcome along the route and on the beaches at Newcastle. The nearby Murlough Nature Reserve permits dogs on leads year-round, though access restrictions may apply during bird nesting season.
- Navigation: Download the official National Cycle Network map or use a GPS device with the NCN route loaded. The yellow-on-black signage is reliable, but having a backup route on your phone helps if you need to detour into a town centre.
- Refreshments: Stock up on water and snacks in Bangor or Downpatrick. While cafes and pubs are plentiful, rural stretches between villages offer limited services.
National Cycleway 99 provides a straightforward, well-connected way to experience County Down’s coastal landscape without the need for specialist off-road gear. Riders who start early, carry basic repair tools, and time their ride to avoid midday summer traffic will find the route offers a reliable and rewarding introduction to Ireland’s expanding cycling infrastructure.
