31k Run Llangollen: Stunning Views of Dee Valley and Moel Ferna

Route Overview & Local Insights

Gear up for a serious mountain excursion starting from the historic town of Llangollen. This 31.0km route is a true test of grit, featuring a staggering 965 meters of vertical gain that takes you deep into the rugged North Berwyn mountains. You’ll tackle the relentless climb up Vivod Mountain early on, transitioning from paved sections to wild mountain trails. The segment toward Moel Ferna represents the peak of the challenge, both in altitude and technicality. Expect rocky paths and loose gravel on the descent into Carrog that will put your trail shoes and stabilizers to the test. The final stretch offers a complete change of pace, swapping technical ridges for the tranquil, flat towpaths of the Llangollen Canal—a welcome respite for tired legs to finish strong.

Located within the Clwydian Range and Dee Valley Area of Outstanding Natural Beauty, this run traverses a landscape steeped in Welsh history and industrial heritage. As you traverse the high ridges, you are running through lands once navigated by Owain Glyndŵr, the last native Prince of Wales. The Dee Valley below is famous for the Pontcysyllte Aqueduct and the heritage steam railway that you’ll often hear whistling from the valley floor. While the Berwyns are often quieter and more secluded than the neighboring Snowdonia peaks, their expansive heather moorlands and steep valleys offer a raw, untouched running experience that captures the essence of the North Wales uplands.
