Standing tall at 126 feet above the River Dee, the Pontcysyllte Aqueduct in Wrexham, North Wales, is one of Britain's most spectacular engineering marvels. This UNESCO World Heritage Site, affectionately known as the 'Stream in the Sky', offers visitors a truly unique experience walking or boating across its 1,007-foot span.
A Masterpiece of Industrial Revolution Engineering
Designed by Thomas Telford and completed in 1805, the aqueduct represents a brilliant solution to the challenge of carrying the Llangollen Canal across the Dee Valley. Its 18 stone piers support a cast iron trough just 11 feet wide, creating an exhilarating crossing with panoramic views of the Welsh countryside.
What Visitors Can Experience
- Canal boat trips: Several operators offer crossings, including horse-drawn boats for an authentic 19th-century experience

Why It's Special
What makes Pontcysyllte extraordinary is its combination of breathtaking height, elegant design, and continuing functionality after more than 200 years. The aqueduct remains in daily use by narrowboats, making it the highest navigable canal structure in the world.
For those seeking adventure with spectacular views, this Welsh wonder delivers an experience unlike any other canal crossing in Britain. Whether you choose to walk, cycle, or float across, the memory of looking down through the iron trough to the river far below will stay with you long after your visit.
