Soar above the Dee Valley on the Pontcysyllte Aqueduct, a breathtaking feat of engineering and a UNESCO World Heritage Site in North Wales. Opened in 1805 and designed by Thomas Telford, this magnificent aqueduct carries the Llangollen Canal 38 metres above the River Dee on a slender cast-iron trough. Whether you walk across, cruise by narrowboat, or admire it from below, Pontcysyllte offers an unforgettable blend of history, adventure, and stunning scenery.
Known as the “Stream in the Sky,” Pontcysyllte is the longest and highest aqueduct in Britain. Its elegant 18 stone piers and soaring iron trough were revolutionary in their day, and more than 200 years later, it still inspires awe as one of the greatest works of the Industrial Revolution.
Walking across the aqueduct is a thrilling experience. With only a narrow towpath and no rail on the canal side, you’ll feel as though you’re floating above the valley, rewarded with spectacular panoramic views of the surrounding countryside and mountains.
For a gentler way to experience Pontcysyllte, hop aboard a narrowboat cruise. Drifting across the aqueduct by boat offers a peaceful, almost surreal perspective – gliding through the sky with the Welsh hills as your backdrop.
The aqueduct is part of 11 miles of the Llangollen Canal designated as a World Heritage Site. Walking or cycling along the towpaths reveals picturesque villages, lush valleys, and other feats of canal engineering such as Chirk Aqueduct and tunnels.
From dawn mist to golden sunsets, Pontcysyllte is a paradise for photographers. Views from below highlight the aqueduct’s monumental scale, while shots from the top capture its dizzying heights and breathtaking landscapes.
