Hiking in Denbighshire
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”. 😂😂

A nice little stop with the pooch and I both getting an ice-cream, plenty of seating outside in a big garden right next to the waterfall

The loop from Llandrillo going anticlockwise is very steady and pleasant. But be prepared for substantial bog trotting in the central part of the valley passing the area marked as Gwern Wynodl. Even with newish goretex boots, we came away with wet feet. Good boots and gaiters, or wellies for that section highly recommended. Return section (first section if doing it clockwise) is also pretty boggy in parts. It also seemed like a bit more of a slog doing it clockwise.

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.

The area is popular with walkers, cyclists and tourists. The Offa's Dyke Path passes through World's End. World's End lies on a single track road from the small village of Minera near Wrexham, which crosses Esclusham Mountain and the Ruabon Moors to a public car park at the top of the Eglwyseg valley. The road crosses the Eglwyseg River by a ford, then goes on towards Pentre Dŵr, under the Horseshoe Pass, leading eventually to Llangollen or onto the Panorama in Trevor. Near World’s End is the manor house Plas Ucha yn Eglwyseg, built in 1563. It was for a time the home of John Jones Maesygarnedd, one of the signatories of the death warrant for Charles I of England. The building is said to stand on the site of a hunting lodge of Owain ap Cadwgan, prince of Powys, where Owain carried Nest (daughter of Rhys ap Tewdwr) when he stole her away from her husband Gerald de Windsor in 1109.

There is a small charge to go through the hole waterfall, but you can take photos of the one that is open to the public

The Ancient Horse Chestnut Trees also provide a gentle, engaging natural setting for all ages.

If you enjoy cycling, there are gravel biking trails, particularly around Llyn Brenig, detailed in the Gravel biking in Denbighshire guide. General hiking trails are also available in the Hiking in Denbighshire guide.
Many natural areas in Denbighshire are dog-friendly, provided dogs are kept under control, especially around livestock. The Dyserth Waterfall is noted as dog-friendly. The wider Clwydian Range and Dee Valley AONB, including areas around Moel Famau and Moel Fferna, generally welcome dogs on leads along public footpaths.
The best time to visit Denbighshire's natural monuments largely depends on your preferred activities. Spring and summer offer pleasant weather for hiking and enjoying the vibrant flora, especially at sites like Graig Fawr. Autumn brings stunning colours to the hills and valleys. While some areas are accessible year-round, be prepared for potentially wet and windy conditions during winter, particularly on higher peaks.
For a more tranquil experience, consider exploring the Berwyn Mountains, which include peaks like Cadair Bronwen Summit Cairn and Moel Fferna. These areas, part of the Clwydian Range and Dee Valley AONB, offer wild, heather-clad moorland and opportunities for long walks away from the busiest spots.
Denbighshire's natural monuments showcase significant geological diversity. Graig Fawr, for instance, is a Site of Special Scientific Interest due to its unique limestone habitat.

Yes, history is often intertwined with Denbighshire's natural beauty. The Jubilee Tower on Moel Famau is a Grade II-listed monument built in 1810. The Horseshoe Falls, while appearing natural, is a significant piece of engineering designed by Thomas Telford in the early 19th century to feed the Llangollen Canal, forming part of a World Heritage Site.
The terrain varies significantly across Denbighshire's natural monuments. You can find easy, flat paths around areas like the Horseshoe Falls or Dyserth Waterfall. However, many summits like Moel Famau, Moel Fferna, and Graig Fawr Summit involve intermediate to difficult climbs with steep sections and uneven paths. The Berwyn Mountains offer wild, moorland terrain suitable for experienced walkers.
Parking is often available at or near popular natural monuments, such as designated car parks for Moel Famau or the Llantysilio Green Car Park for Horseshoe Falls. For specific public transport routes, it's advisable to check local bus services or plan your journey in advance, as some more remote sites may have limited access.
