The Chirk Walk via Two Aqueducts: Canal Paths, Tunnels, and Industrial Heritage

Starting the Walk at Chirk Railway Station

The Chirk walk via two aqueducts is one of the most memorable canal and countryside walks on the England–Wales border, combining dramatic engineering, industrial heritage, and peaceful Welsh valleys. I began at Chirk railway station, arriving on a slightly delayed train from Chester, accompanied by an enthusiastic (and occasionally disobedient) Jack Russell on a long extending lead.

The elevated aqueduct is flanked by leafless trees and a pedestrian path, with walkers in the distance. The tribute suggests remembrance at a significant drop, adding a quiet, reflective tone to the winter scene.

From the station, the canal towpath is easy to find, making this an accessible walk for those arriving by public transport. Before making my way down to the canal side, the sheer drop is striking. A small bunch of flowers left near the edge gave pause for thought, reminding walkers that these beautiful places also carry human stories.

Crossing Chirk Aqueduct: The First Highlight

The first major landmark is Chirk Aqueduct, often described as the “little brother” of Pontcysyllte Aqueduct. Despite the nickname, it is an impressive structure. Walking across, you can admire the flat, calm surface of the canal on one side and the dramatic drop into the valley on the other. Narrowboats drift past, adding to the sense of timelessness.

A belted dog lead is ideal for ensuring the dog remains safe when crossing the aqueduct.

The Chirk Canal Tunnel: A Dark but Memorable Section

After crossing Chirk Aqueduct, the it is necessary to walk back along the canal towards Chirk railway station toward the Chirk Canal Tunnel.

Entrance to Chirk Tunnel on the Llangollen Canal, showing calm water leading into the arched stone tunnel. A towpath with metal railing runs alongside the canal, continuing into the tunnel. Reflections in the still water create a symmetrical, atmospheric scene highlighting historic canal engineering.
Light at the end of Chirk Tunnel

The tunnel is long and completely dark. I hadn’t brought a torch—something I would strongly recommend. My dog disliked the tunnel so much that I carried him for the first part, while other walkers passed confidently with head torches. Despite the darkness, there really is light at the end.

A head mounted torch light is great for passing through lengthy canal tunnels.

Durable LED headlamp with adjustable black and green strap, designed for outdoor use. Features high, low, SOS, and off modes for versatile lighting during hiking, trekking, and trail navigation. Rugged black casing with orange accents ensures reliable hands-free illumination in challenging environments.

Industrial Heritage Along the Canal

Emerging from the tunnel, the walk opens into a stretch rich in industrial heritage. Narrowboats glide quietly along the canal, harking back to the Industrial Revolution. Sheep graze in the surrounding Welsh valley, while a large factory vents steam nearby, symbolising the final chapter of fossil-fuel industry.

Two narrowboats moored along the Llangollen Canal, one with a green tarp and rising chimney smoke. A grassy embankment with staircase leads to a parking area with cars and vans. Leafless trees and dry reeds suggest late autumn or winter, capturing the quiet rhythm of canal life.

Pontcysyllte Aqueduct: The Big Brother

After a lunch stop, we reached the centrepiece of the walk: Pontcysyllte Aqueduct, a UNESCO World Heritage Site. Its scale is difficult to comprehend until you stand on it. Walking across, the drop into the River Dee valley below is breathtaking. The combination of historic engineering, natural beauty, and good weather made this the highlight of the day.

Coffee Stop and the Return Journey

Before heading back, we stopped at a canal boat coffee bar for a much-appreciated cappuccino and KitKat. As daylight faded, we chose to return via the roadside rather than re-enter the tunnel, especially as the dog had no desire to repeat the experience.
