The loop typically starts from the village of Knock. Parking is usually available in or near the village, but it's advisable to check local signage for specific parking regulations and availability, especially during peak seasons. There is no specific mention of a dedicated car park for this exact loop, so roadside parking in the village is often utilized.
Yes, dogs are generally welcome on this trail. However, as much of the route traverses open moorland and farmland where sheep and other livestock graze, it is crucial to keep dogs on a lead at all times. Be aware of aggressive cattle guards mentioned on the descent, which might be challenging for some dogs.
The best time to hike this loop is typically during the warmer, drier months, from late spring to early autumn. This avoids the harshest winter conditions and reduces the likelihood of boggy terrain, especially on the approach to Knock Fell. Clear days offer the most spectacular panoramic views.
No, there are no specific permits or entrance fees required to hike the Great Dun Fell and Knock Fell Loop, even though it passes through the Moor House-National Nature Reserve. However, visitors are expected to follow the Countryside Code, respecting wildlife, livestock, and the natural environment.
The terrain is quite varied and challenging. You'll encounter old mine tracks, sections of heather and grass that can be 'squelchy' or boggy, especially towards Knock Fell. Parts of the trail follow slabbed sections of the Pennine Way. The final ascent to Great Dun Fell is via Britain's highest paved road, which is in pristine condition, while the descent may involve navigating areas with aggressive cattle guards.
The trail offers several distinctive features. You'll pass a Clapper Bridge Over Great Rundale Beck. The summit of Knock Fell is marked by the Knock Fell Summit Cairn. A major highlight is the distinctive 'golf ball' shaped Great Dun Fell Radar Station on the summit of Great Dun Fell. On clear days, the views are expansive, stretching across the Lakeland Fells to peaks like Helvellyn and Skiddaw.
This challenging hike typically takes around 5 to 6 hours to complete, depending on your pace, fitness level, and how long you spend enjoying the views. The total duration is approximately 5 hours and 20 minutes of moving time.
Yes, the route significantly overlaps with several well-known paths. A substantial portion (53%) follows the Pennine Way (Middleton in Teesdale to Kirk Yetholm), and it also incorporates sections of the Great North Trail (North Pennines and Kielder Forest) for 38% of its length. Smaller parts also align with the Cumbria Cycleway and the Lakes & Dales Loop.
Given the varied terrain and exposed nature of the fells, it's essential to be well-prepared. Wear sturdy, waterproof hiking boots, as sections can be boggy. Layered clothing is recommended to adapt to changing weather conditions, which can be unpredictable. Always carry waterproofs, a map and compass (or GPS device), sufficient water, snacks, and a first-aid kit. Sun protection is also advisable on clear days.
This loop is rated as 'difficult' and requires 'very good fitness' and 'sure-footedness'. Due to significant elevation gain, steep gradients, and varied, sometimes pathless or boggy terrain, it is generally not recommended for beginners or young children. It's best suited for experienced hikers looking for a challenging day out.
The trail itself is remote, with no facilities directly on the route. The nearest amenities, such as pubs or cafes, would be found in nearby villages like Knock or Dufton. It's crucial to carry all necessary food and water for the duration of your hike.
