History of Barnagh Tunnel
A Hidden Gem on the Limerick Greenway
Step back in time at one of Limerick’s most fascinating heritage sites
Built in 1880 as part of the Limerick–Tralee railway, Barnagh Tunnel cuts through the Barnagh Hills at the highest point on the route. This 100-metre stone-lined tunnel, once echoing with steam trains, is now a dramatic highlight along the Limerick Greenway walking and cycling trail.
A Bit of History
Barnagh Tunnel was an impressive Victorian engineering project, carved through solid rock to overcome a steep railway gradient. It served passenger and goods trains until the line closed in the 1970s. After decades of disuse, the tunnel was carefully restored and reopened to the public in 2019.
