Overview
Union Locks sits at the Lisburn end of the 11‑mile Lagan towpath, the heart of Lagan Valley Regional Park – Northern Ireland’s only designated regional park. Spanning roughly 4,200‑4,500 acres of riverbank, woodland and historic sites, the park is an Area of Outstanding Natural Beauty that offers a blend of gentle riverside walks, wildlife spotting and a glimpse into the region’s industrial past. Union Locks itself is a small but charming hub where the historic Lagan Canal terminates, providing a convenient entry point for walkers, cyclists and families.
History
The Lagan Canal was engineered in the late 18th century to link Belfast with Lough Neagh, facilitating the transport of timber, coal and linen. By 1794 a flight of locks at Sprucefield (near Union Locks) opened the waterway to commercial traffic. The canal thrived through the 19th‑century industrial boom, but the rise of railways and motor transport led to its gradual decline. By the mid‑20th century the section above Lisburn was abandoned, and the M1 motorway now follows much of the old canal route.
Today, the canal’s legacy lives on at Union Locks. The Lock Keeper’s Cottage, still standing beside the towpath, houses an original Lagan canal barge, offering a tangible link to the waterway’s bustling heyday. The site is part of a broader heritage trail that includes nearby historic attractions such as the Giant’s Ring, a 5,000‑year‑old henge, and the former linen‑industry sites that once dotted the valley.
What to See & Do
- Lock Keeper’s Cottage & Barge – Step inside the restored cottage to view the original canal barge, a rare survivor of the Lagan navigation. Interpretive panels explain the daily life of a lock‑keeper and the engineering feats of the canal.
- Riverside Café – A modest tea‑room on site serves coffee, tea and light snacks, making it a pleasant stop after a walk along the towpath.
- Towpath Walks – The towpath is level and well‑maintained, ideal for leisurely strolls, jogs or family bike rides. From Union Locks you can head north toward Belfast, passing landmarks such as Shaw’s Bridge, Sir Thomas & Lady Dixon Park and the Giant’s Ring.
- Wildlife Watching – The Lagan corridor supports kingfishers, otters, reed buntings and a variety of butterflies. Early mornings are especially rewarding for bird‑watchers.
- Picnic Areas – Open grassy patches near the lock provide space for picnics, especially on sunny days.
- Connecting Trails – Union Locks links to several themed routes, including the Lagan Towpath – Shaws Bridge to Lock Keepers Cottage walk and the Giant’s Ring Trail, both sign‑posted and suitable for all abilities.
