Overview
The best of the Lagan Canal is its towpath: an 11-mile (18 km) tarmac path running from the Lagan Weir in central Belfast out to Union Locks in Lisburn, flat the whole way and smooth enough for a road bike, a buggy or a wheelchair. It forms part of National Cycle Network Route 9 and the Ulster Way, and it follows the line of the historic Lagan Navigation, the 27-mile (44 km) canal that once carried coal, timber, grain, linen and sand between Belfast Harbour and Lough Neagh.
The path threads through the 4,300-acre Lagan Valley Regional Park, an Area of Outstanding Natural Beauty designated in 1965, with wetlands, riverside meadows and mixed woodland along the way. One thing worth knowing: the full canal no longer runs unbroken to Lough Neagh – the M1 motorway was built over the central section in the 1960s – but the Belfast-to-Lisburn stretch that most people walk is continuous.
History and heritage
Work on the Lagan Navigation began in 1756 under the engineer Thomas Omer, who cut new channels, built the locks and laid a towpath that reached Lisburn by 1763. A second phase under Richard Owen pushed the navigation up to the summit level at Aghalee and on to Ellis’ Gut on Lough Neagh by 1794. The finished waterway cost £62,000 and ran through 27 locks, including a dramatic ten-lock flight at the summit and an aqueduct at Spencer’s Bridge.
At its height the navigation carried coal, timber, grain, linen and sand between Belfast’s port and the inland markets, connecting via the Ulster Canal toward the Shannon–Erne system. Railways and roads eventually undercut it: the upper section closed in 1954, the lower in 1958, and the M1 later cut through the central stretch, leaving the canal in two separate parts.
Restoration picked up in the 2000s under the Lagan Navigation Trust. The towpath was resurfaced in smooth tarmac, Lock 3 was restored, and the Lock Keeper’s Cottage at Lock 12 was rehabilitated. The historic lighter The Industry was floated again in 2014 and now works as a small living museum and café.
The Lagan Weir and Laganside
In central Belfast the Lagan Weir anchors the modern Laganside regeneration. Conceived in the late 1980s and built with £14 million of public funding, it opened in March 1994 after the Prince of Wales set the first pile in 1991 and the steel gates were lifted in 1992. The weir holds the river at a constant level, ending the tidal mudflats that once lined the city-centre banks. Beside it, the Lagan Lookout visitor centre at 1 Donegall Quay is free to enter (check current opening times before a special trip), and a wider footbridge added in 2014 improved the crossing for cyclists and walkers.
What to see and do
- Lock Keeper’s Cottage and The Industry: At Lock 12, the restored cottage has a café, toilets and volunteer guides, with the lighter The Industry alongside as a small museum. Opening is volunteer-dependent, so ring the park office to check before setting out.
- The Lock Keeper’s Inn: A separate pub-restaurant at Lock 12, open since 2007, handy for lunch or a coffee partway along the towpath.
- Shaw’s Bridge: An elegant 18th-century stone bridge and one of the prettier crossings on the route.
- Spencer’s Bridge Aqueduct: A rare survival of early canal engineering, carrying the waterway over the road.
- Wildlife watching: The Regional Park draws over 1.4 million visitors a year; its wetlands and meadows are good for birds year-round.
If you’ve only time for a short stretch, the section around Shaw’s Bridge and the Lock Keeper’s Cottage is the one to pick – a few easy miles with somewhere to get a cup of tea at the end.
Practical information
- Access: The towpath is signposted and can be joined at many points; the main ones are the Lagan Weir in Belfast and Union Locks in Lisburn.
- Opening times: The towpath is open 24/7, subject to occasional maintenance closures. The Lock Keeper’s Cottage and The Industry open Monday to Friday 10am–4pm and the last weekend of each month 11.30am–3.30pm, but this depends on volunteers – closed other weekends and bank holidays.
- Facilities: Accessible toilets at the Lock Keeper’s Cottage and Sir Thomas & Lady Dixon Park; more toilets and car parks at McIlroy Park and other points in the park. Bike hire is available in Belfast.
- Transport: Both ends are served by Translink buses, and the Belfast end is a short walk from Great Victoria Street railway station.
- Nearby: Belfast’s Cathedral Quarter, the town of Lisburn, and the Broadwater lake beyond Union Locks.
For a full day, start at the Lagan Weir and Lookout, then follow the towpath inland (south-west) toward Lisburn, stopping at the Lock Keeper’s Cottage at Lock 12 for a break and a look at The Industry.
