Keswick to Threlkeld Railway Path: A Scenic Lake District Walk for Everyone
The Keswick to Threlkeld Railway Path is one of the most accessible and enjoyable routes in the northern Lake District. Following the route of the former railway line between Keswick and Threlkeld, the trail combines riverside scenery, woodland, historic railway features, bridges and spectacular views into the surrounding fells.
With a smooth surface and very gentle gradients, it is suitable for walkers of all abilities, as well as cyclists, runners, wheelchairs and mobility scooters.
For visitors staying in Keswick, it is an ideal way to enjoy the countryside without needing to tackle a steep fell walk.
Please note: The western end of the trail is currently subject to temporary bridge works from 17 September 2026, with the affected bridge expected to be closed for around eight weeks. The eastern section towards Threlkeld remains accessible via an alternative access point. Check the latest Lake District National Park information before setting out.
A Walk Through Keswick’s Railway History
The trail follows approximately 5km of the former railway route between Keswick and Threlkeld, giving a total distance of around 10km (6.2 miles) there and back.
The original railway formed part of the Cockermouth, Keswick and Penrith Railway. The railway eventually closed, with the last train leaving Keswick in 1972. Today, much of the former railway route has been transformed into a peaceful multi-use trail.
Along the way, information panels tell the story of the railway, local wildlife, the River Greta and the devastating impact of Storm Desmond in 2015.
The route reopened in December 2020 following a major reconstruction project. Two bridges were replaced, another was repaired and the former damaged section of the trail was rebuilt. The project also saw the reopening of the historic Bobbin Mill Tunnel.
Starting the Railway Path from Keswick
The traditional starting point is close to Keswick Leisure Centre and Fitz Park, where the former Keswick railway station can still be seen.
From the centre of Keswick, the route is easily reached on foot, making it particularly convenient if you’re staying in town.
The trail then heads east, following the old railway line through the Greta Gorge.
The surface is tarmac throughout and gradients are very gentle, with level access at the Keswick end. There are also regular benches along the route, making it easy to stop and enjoy the scenery.
Follow the River Greta
One of the highlights of the walk is the changing scenery along the River Greta.
The river winds its way through the gorge, with wooded slopes and rocky sections creating a peaceful contrast to the open landscapes around Derwentwater.
Keep an eye out for local wildlife too. The fast-flowing river provides habitat for birds including dippers and herons.
The combination of woodland, river and mountain scenery makes this a particularly enjoyable route when the weather isn’t perfect for a high-level fell walk.
Through the Bobbin Mill Tunnel
One of the most memorable features of the Railway Path is the Bobbin Mill Tunnel.
The tunnel was originally associated with the old railway route but was later buried during construction work in the 1970s. As part of the major trail reconstruction, it was excavated and reopened, replacing a former boardwalk section of the route.
Walking through the tunnel gives the route a real sense of history — and it is one of the features that makes this more than simply a riverside path.
There is a picnic area and seating close to the tunnel, providing a good place to pause before continuing towards Threlkeld.
Continuing Towards Threlkeld
After the tunnel, the trail continues through the Greta Gorge, crossing a number of railway bridges as it gradually makes its way towards Threlkeld.
Eventually, the path reaches the A66 before continuing towards the village of Threlkeld.
Threlkeld sits beneath Blencathra, one of the Lake District’s most recognisable mountains, and makes a rewarding destination after the relatively gentle walk from Keswick.
The village has pubs and a café, making it a good place to stop for refreshments before returning to Keswick.
Walking Back to Keswick
The simplest option is to return to Keswick along the same route.
Because the trail is relatively flat and follows the old railway alignment, the return journey is straightforward and gives you an opportunity to appreciate the scenery from a different perspective.
Alternatively, there is a regular bus connection between Threlkeld and Keswick, meaning the walk can be done as a one-way linear route rather than returning on foot.
That can be a particularly useful option if you’re looking to reduce the overall distance.
Is the Keswick to Threlkeld Path Suitable for Everyone?
This is one of the great advantages of the route.
Unlike many of the more challenging walks around Keswick, the Railway Path has been specifically designed to provide an accessible route through the landscape.
The trail has:
- A smooth tarmac surface
- Very gentle gradients
- Level access at the Keswick end
- Seating along the route
- A zigzag section at the Threlkeld end to reduce the gradient
- Access for walkers, runners, cyclists, wheelchairs and mobility scooters
The Lake District National Park categorises it as a Miles Without Stiles “Route for All”.
That makes it an excellent choice for families, visitors who prefer a low-level walk and anyone who wants to experience some of the Lake District’s scenery without climbing a mountain.
How Long Does the Railway Path Take?
The full Keswick to Threlkeld route is approximately 10km (6.2 miles) there and back. The Lake District National Park gives a walking time of around 2½ hours for its route assessment, although your actual time will depend on your pace and how often you stop.
You don’t have to walk the whole route either.
Because it’s an out-and-back trail, you can simply walk as far as you wish before turning around.
That makes it particularly useful when travelling with children or when you want a shorter afternoon walk.
