Dare you cross it? And can you do it without looking down! Designed and built by Thomas Telford and Williams Jessop, Pontcysyllte means 'the bridge that connects' and is 'the jewel in the crown' of this World Heritage Site. You can walk across Pontcysyllte, or save your legs and take a leisurely boat ride or even hire a boat for the day from Trevor Basin. You can walk back along part of the Offa’s Dyke Path route and see the Aqueduct from the ground, but don’t forget your camera, the views are stunning.
