Route Overview
The Llangollen Round is a circular hiking route that begins and ends in the historic market town of Llangollen, North Wales. From the town center, the trail heads out to take in prominent local landmarks including Castell Dinas Brân, Llantysilio Mountain, the Berwyn Range, and Moel y Gamelin, before looping north towards the Horseshoe Pass and returning via Velvet Hill and various valleys and woodlands. Key villages and stops along the way include Trevor, Llantysilio, and areas adjacent to the Llangollen Canal and Pontcysyllte Aqueduct. The route is well established among long-distance hikers and offers sections that can be broken down for shorter itineraries or tackled as a multi-day adventure.
The loop covers approximately 53 kilometers with a cumulative elevation gain of around 2,000 meters. Most hikers complete the circuit over two days, although experienced walkers may complete it in a single long day. The trail surfaces vary and include dirt paths, rocky outcrops, gravel, and grassy hillside tracks. While some sections are well-trodden and straightforward, others—particularly on open moorland or steep climbs—require attentive navigation and solid hiking ability. Accommodation options are accessible in Llangollen and surrounding villages, and there are limited campsite and wild camping opportunities along remote sections of the route.
Historical Background of the Llangollen Round
The Llangollen Round traverses a region steeped in history, where ancient tracks and hill forts have witnessed centuries of human activity. One of the trail’s most notable landmarks is Castell Dinas Brân, a medieval castle perched dramatically above the valley. Built in the 13th century, the castle served as a strategic stronghold for native Welsh princes and has become entwined in legends of heroism and resistance.
The route also follows paths once used for local trade and sheep farming, passing close to sites that have been inhabited since the Iron Age. The area’s natural passes and river crossings played crucial roles in shaping local communities and defense strategies. The town of Llangollen itself boasts a rich heritage, featuring the iconic Llangollen Canal—a masterpiece of industrial engineering—and the Pontcysyllte Aqueduct, a UNESCO World Heritage Site, bringing further historical significance to the journey for modern-day hikers.
By walking the Llangollen Round, hikers not only experience breathtaking Welsh landscapes but also walk in the footsteps of ancient settlers, medieval knights, and generations of local villagers whose lives shaped the valleys and hills of this picturesque corner of Great Britain.

Challenges to expect
The Llangollen Round is a demanding undertaking, with a total distance of 53 kilometers and significant elevation gain—approximately 2,000 meters overall. Expect long hours on your feet, particularly on steeper ascents such as the climb to Moel y Gamelin and the approach to Castell Dinas Brân. The undulating terrain, including rocky and uneven sections, can test both your endurance and balance, especially after rain when paths become slick.
Weather in North Wales is famously changeable, with conditions ranging from warm sunshine to mist, wind, and occasional driving rain—even during the optimal hiking seasons of spring, summer, and autumn. Visibility can drop suddenly on the high moors and mountain tops, so it’s crucial to be prepared with waterproofs and layered clothing. Muddy and boggy patches are also common, particularly on exposed upland sections and in shaded woodland areas.
Navigation requires careful attention, as waymarking may be sparse on certain parts of the loop, especially in remote stretches. Carrying a detailed map, compass, or GPS device is essential. Finally, access to water and facilities is limited along the wilder sections, so plan to carry sufficient supplies and be prepared for self-sufficiency between villages or resupply points.
