Messing about in boats takes on a whole new dimension at the Llangollen canal in North Wales. In this area that’s popular with visitors thanks to its lush green countryside and historic Welsh castles, one place – quite literally – stands above all others.

Pontcysyllte Aqueduct – known as the “Stream in the Sky” – is more than just another Victorian edifice.

It’s easy to visit Pontcysyllte Aqueduct and Llangollen Canal as part of a guided adventure tour of North Wales from Liverpool, Manchester, or Chester.

About the Pontcysyllte Aqueduct and Llangollen Canal

Pontcysyllte Aqueduct is part of a canal system connecting the lowlands of England with the rugged Welsh hills.

The Llangollen Canal, which includes the Pontcysyllte aqueduct, runs from Cheshire in Northwest England to Llangollen in Wales.

Pontcysyllte is the longest aqueduct in Britain and thehighest canal aqueductin the world.

From the early days of the Industrial Revolution, horse-drawn canal barges carried coal, iron, slate, and limestone from Welsh mines to coastal ports for export and to English industrial towns and cities.

Once road and rail transport became cheaper and quicker than the canals, they were abandoned before being transformed into a beautiful leisure network.

How long did the Pontcysyllte Aqueduct take to build?

The stone and cast iron Pontcysyllte Aqueduct took ten years to design, build and test – from 1795 – it finally opened on 17th November 1805 after six months of testing to make sure there were no leaks!

18 massive, tapering pillars support the 126ft high aqueduct, which has 19 arches, each with a 45ft span.

Water is carried over the aqueduct in a trough made from cast iron plates. The trough is just under 12ft wide and is 5ft 3in deep. It’s a true marvel of early Victorian engineering.

Pontcysyllte Aqueduct was designed to carry the Llangollen Canal over the River Dee, connecting England and Wales and the rivers Severn, Dee, and Mersey.

Who Built the Aqueduct?

The aqueduct is the masterpiece of famed Scottish civil engineer Thomas Telford (1757-1834).

His projects also included the Caledonian Canal, the Menai Suspension Bridge, the incredible Neptunes Staircase in Banavie, Scotland, and The Iron Bridge – the world’s first iron bridge.

Telford was so influential that he became the first president of the Institute of Civil Engineers in 1820.

Two other eminent Victorians were key to the success of the project:

  • Consulting engineer: William Jessop (23 January 1745 – 18 November 1814)
  • Structural engineer: William Hazeldine (6 April 1763 – 26 October 1840)

Gaining UNESCO World Heritage Status

In recognition of the feat of civil engineering employed in designing and building the aqueduct, the Grade 1 listed structure and the Llangollen Canal were awarded UNESCO World Heritage Site status in June 2009.

The World Heritage site includes the two most famous aqueducts in Wales: Pontcysyllte Aqueduct and Chirk Aqueduct, plus the Chirk Viaduct, tunnels, cuttings, and 11 miles of the Llangollen canal, running from Gledrid Bridge near Rhoswiel to the incredible Horseshoe Falls.

The Pontcysyllte aqueduct is 1,007ft long, which doesn’t sound very far, but the incredible height is what makes this walk along a narrow towpath so thrilling.

The canal towpath itself is mounted above the water, with sturdy railings to prevent any accidents (and to hold onto if you suffer from vertigo).

The ultimate view is from the centre of the aqueduct, high above the River Dee and the valley over 100ft below. I was proud I managed to conquer my fear and walk Pontcysyllte Aqueduct (even though my knees were knocking the whole time).

A couple of safety tips:

  • If you’re travelling with small people – hold on tight to them when crossing the aqueduct!
  • Be aware that the towpath is two-way – pedestrians, wheelchairs, buggies and bikes (cyclists must dismount).

4. Walk Down the Valley to the River Dee

After a lofty crossing of the aqueduct, wander down (a lot of steps) to the banks of the River Dee for a completely different perspective of the area and the aqueduct. It’s a very pleasant walk, but remember – all those steps need to be climbed back up again!

Downstream from the aqueduct, a narrow (single lane) bridge on the B5434 road crosses the River Dee – moments from the Trevor Basin car park.

There’s no formal parking at this point, but you can park safely on the (steep) hill down to the bridge before walking across the bridge to take in the view upstream towards the aqueduct.

6. Explore the Llangollen Canal

The walks along the Llangollen canal are stunning- even if you’re not usually much of a walker. There are bus stops along the way and plenty of benches to sit on and watch narrowboats pass by. If you’re lucky, you’ll spot herons too.

Pubs along the route include the Telford Arms and the Cornmill at Llangollen, and you will find cafes at both ends of the canal between the Pontcysyllte aqueduct and Llangollen.

  • The level, easy walk to the gorgeous Horsehoe Falls takes between 30 mins and 1 hour, depending on your pace.
  • A gentle walk from the town of Llangollen towards the viaduct (4 miles) will take about 1 hour – you can either make it a circular walk or catch a bus back from the Trevor basin.
  • From Pontcysyllte, there’s also a lovely 4-mile walk to Chirk Aqueduct through two very dark tunnels – remember to pack a torch! Alternatively, hire a bicycle at Trevor – it’s a very pleasant 1 to 1 1/2 hour round trip.

Pontcysyllte Aqueduct FAQs

How do you pronounce Pontcysyllte?

Pontcysyllte is a Welsh word that means “the bridge that connects”. It’s pronounced pont – ker – sulth – the, but it’s also known locally as “Ponty”.

Is the Aqueduct one way?

The aqueduct is two-way – both for narrowboats and for pedestrians.

How often is the aqueduct drained for maintenance?

Every five years, both ends of the aqueduct are closed. A plug located in one of the highest spans is opened to drain the canal water to allow inspection and maintenance of the trough.

It takes at least 3 seconds for the water plume to reach the River Dee, 111 feet below. The trough was last emptied in 2019, so the next time to see this spectacle will be in 2024.
