Located on the River Dee, near to Llantysilio, this masterpiece of Thomas Telford Engineering is where the Pontcysllte Aqueduct and Canal World Heritage site begins. He designed this weir to draw water from the River Dee in to the canal, and it became a stunning addition to the landscape. At 460ft (140M) long, it’s a sight to behold.

This year the area has been spoiled by traffic queues and very dangerous parking along the approach road. Emergency vehicles were unable to get through, and the locals were distressed. The falls are quite easy to reach by walking along the canal from Llangollen.
