The Llantysilio Green weir, more commonly known as the Horseshoe Falls, is a 140-meter-long, horseshoe-shaped weir designed by Thomas Telford in 1808 to divert water from the River Dee into the Llangollen Canal. This prominent structure is a significant piece of engineering and a feature of the World Heritage Site, providing water for the canal and attracting tourists with its unique design and surrounding landscape. The Llantysilio Green Car Park is a designated access point for visiting the falls. In the late 19th century a long piece of wood, about 30cm wide, floated on the water here to deflect floating debris away from the canal intake. It was fixed at one end. It’s visible in the photo, taken c.1890. Some trippers couldn’t resist the temptation to walk along it, ignoring a warning sign nearby, if they weren’t spotted by the “waterman” in charge of the sluice. Local residents took a dim view of such “unheeding folly”. 😂😂

Not too technical and interesting climb from the gate at the top of the llandegla MTB climb. Straight up to the mast, swing left after it, and if you're lucky it will be bone dry like it was for us. My partner struggles on techy stuff, but this was fine. Awesome scenery, if you stop to look at it that is😉

Though it was not a tough or technical ride, it did take me into territory I had never visited before and was a lovely antidote to the 'fleshpots' of Gwydir Forest or Coed-y-Brenin. Some lovely gentle singletrack, beautiful views and I didn't see another rider for the whole trip - although tbh I did set off at 08.30 on a Wednesday!!

With stunning views of the fast-flowing River Dee, two hundred-year-old chain bridge & Llangollen’s popular steam railway, it is hard to think of a more beautiful setting in which to relax, explore & unwind.
