Overview
The Lagan Waterway stretches from Belfast Harbour to Union Locks in Lisburn, linking the bustling Stranmillis district with the tranquil Lough Neagh. It comprises the historic Lagan Canal (also called the Lagan Navigation), a 27‑mile (44 km) navigation of river sections, artificial cuts and the Broadwater lake, and a 11‑mile (18 km) towpath that forms part of the Ulster Way and National Cycle Network Route 9. In the heart of Belfast the modern Lagan Weir (opened 1994) controls water levels and anchors the Laganside promenade, complete with a free‑entry visitor centre. The tarmac‑surfaced, wheelchair‑friendly route makes it one of Northern Ireland’s most accessible outdoor corridors.
History / Background
- 1756‑1794 – Construction: Engineer Thomas Omer began work in 1756, creating new cuts, four locks and a towpath that opened to Lisburn in 1763. A second phase under Richard Owen extended the waterway to the summit at Aghalee and finally to Ellis’ Gut on Lough Neagh in 1794, at a cost of £62 000.
- Peak operation: The navigation featured 27 locks, including a ten‑lock flight at the summit, and an aqueduct at Spencer’s Bridge. It carried coal, timber, grain, linen and sand, linking Belfast’s port with inland markets and, via the Ulster Canal, the Shannon‑Erne Waterway.
- Decline: Water‑supply problems and competition from rail and road led to closure of the upper section in 1954 and the lower in 1958; the M1 motorway later destroyed part of the central stretch.
- Restoration: From the 2000s the Lagan Navigation Trust secured funding to restore key assets – notably Lock 3, the Lock Keeper’s Cottage at Lock 12, and the historic lighter The Industry (returned to water in 2014). The towpath has been resurfaced with smooth tarmac, making it one of Northern Ireland’s most accessible outdoor routes.
- Lagan Weir: Conceived in the late 1980s as the centrepiece of the Laganside regeneration, the weir was built with £14 million of public funding. The Prince of Wales set the first pile on 7 March 1991; the steel gates were lifted in May 1992, and the weir opened in March 1994. A wider footbridge was added in 2014, improving access for cyclists and pedestrians.
What to See & Do
- Lock Keeper’s Cottage & The Industry lighter – Open weekdays; offers a café, toilets and volunteer guides who recount canal life.

- Spencer’s Bridge aqueduct – A rare surviving example of early canal engineering.
- Lagan Lookout (Weir visitor centre) – Free entry, with interactive displays on the river’s ecology and the weir’s role.
- Wildlife and scenery – The towpath threads through wetland, riverside meadows and mixed woodland within the 4,300‑acre Lagan Valley Regional Park, an Area of Outstanding Natural Beauty designated in 1965. Over 1.4 million visitors a year enjoy bird‑watching, photography and seasonal flora.
- Recreational activities – The level, tarmac surface is ideal for walking, jogging, cycling and wheelchair access. The route also links to the Ulster Way for longer hikes.
