About this trail
The greenway follows the line of the old Belfast and County Down Railway between Belfast and Comber, a passenger route that closed in the 1950s. The trackbed sat unused for decades before Sustrans developed it into a traffic-free walking and cycling path, completed in November 2008.
Today it forms part of the National Cycle Network as Route 99, linking the heart of east Belfast out through Dundonald to the County Down town of Comber. The Belfast end sits close to the Titanic Quarter and CS Lewis Square, a nod to the Narnia author who grew up nearby.
More recent improvements widened the path to four metres to give walkers and cyclists more room to share, keeping it one of the most popular everyday cycle and walking routes in greater Belfast.
