The Horseshoe Falls is a picturesque, crescent-shaped weir on the River Dee. Designed by Thomas Telford in the early 19th century, it was built to feed water from the river into the Llangollen Canal, a branch of the Shropshire Union Canal. Before the building of the railways, the canal was used for transporting slate from nearby quarries to the Midlands. Today, the meadow beside the falls is a popular picnic spot and it can be reached by following the canal towpath from Llangollen.
