Pontcysyllte aqueduct is one of the wonders of Wales. Standing 126ft above the River Dee, it carries the Llangollen canal on its journey into England.
The aqueduct is a designated World Heritage Site, which gives it the same status as the likes of the Pyramids and the Great Wall of China... and you can cross it by boat, or on foot.
The area around Llangollen is a popular place for paddlers. As well as the canal the River Dee offers year round opportunities for white water kayaking.
I teamed up with local canoeist Andy Turton who runs guided trips across the aqueduct; and after 2 miles of paddling, we finally reached our destination.
Although you're as safe on there as you are floating on a boat on a very flat section of the canal, it feels slightly more dangerous. I know of nowhere else quite like the aqueduct in terms of the experience you get from paddling over it
As you approach the aqueduct the canal narrows to little more than the width of your arm span, and the ground appears to just fall away.
Your serene paddle takes on a heart pounding edge, with incredible unfolding views.
A reminder of how important location can be, when turning action into adventure.
