Pontcysyllte Aqueduct - Walk or cruise across one of the greatest engineering achievements in Britain.

Spanning the breathtaking Dee Valley in north-east Wales, Pontcysyllte Aqueduct is one of the country's most remarkable historic landmarks. Carrying the Llangollen Canal high above the River Dee, this extraordinary structure is the longest and highest navigable aqueduct in Great Britain and has been recognised as a UNESCO World Heritage Site.

Completed in 1805 by renowned civil engineer Thomas Telford, the aqueduct stretches for over 300 metres (1,000 feet) and stands approximately 38 metres (126 feet) above the river below. Its impressive cast-iron trough carries a single narrowboat channel alongside a pedestrian towpath, offering spectacular views across the surrounding countryside.

Visitors can enjoy an unforgettable walk across the aqueduct or experience it from the water aboard one of the popular canal boat trips that cruise across the structure before returning. Whether viewed from above or below, the aqueduct is an outstanding example of early Industrial Revolution engineering and remains one of Wales' most visited attractions.

Located near Llangollen in Wrexham County Borough, Pontcysyllte Aqueduct is also surrounded by scenic walking routes, canalside paths and beautiful landscapes, making it an ideal destination for families, walkers, photographers and history enthusiasts.
