There is a side of Cumbria that many visitors miss—a landscape of rolling farmland, ancient history, and sweeping sea views that feels a world away from the busy Lake District fells. Stagecoach Route 400 offers the perfect way to explore this hidden corner of England, carrying you from the bustling historic city of Carlisle to the Victorian seaside charm of Silloth.
This isn’t just a commute; it’s a journey through the “Solway Plain,” a place of big skies and gentle landscapes. Whether you are a history buff hunting for abbey ruins, a nature lover seeking the Solway Coast Area of Outstanding Natural Beauty (AONB), or simply looking for a relaxing day out by the sea, the 400 offers a reliable and scenic connection.
What makes this route special
While the Lake District draws the crowds, the Route 400 corridor offers a peaceful alternative. The journey transitions from urban heritage to rural tranquillity, ending with the salt air of the Irish Sea. The route roughly follows the path of the old Carlisle and Silloth Bay Railway, cutting through a landscape that has inspired artists (including J.M.W. Turner) and writers for centuries.
It is a route of contrasts. You start in a city that has guarded the border for two millennia and end in a town designed specifically for Victorian leisure. In between, you pass through market towns and hamlets where life moves at a gentler pace.
A route breakdown: from city streets to sea views
The journey begins in Carlisle, the Great Border City. Before you board at the bus station, you might spare a moment to admire the nearby Citadel towers or the impressive Carlisle Castle, which has watched over this region for 900 years.
As the bus leaves the city, you head west past Newby West. The urban sprawl quickly gives way to green fields as you travel towards Nealhouse.
The first major village on the route is Thursby. Centred around a traditional village green, it’s a lovely example of a Cumbrian rural community. The route continues through the quiet hamlets of Whinnow and Micklethwaite, offering passengers views of the expansive farming country that defines the Solway Plain.
Wigton: a market town with heart
Approximately halfway through the journey, the bus arrives in Wigton. This traditional market town is an excellent place to hop off for a coffee or a wander. It’s a town of red sandstone buildings and a fountain memorial that serves as a local landmark. The bus winds through the town, serving local stops before heading back out into the countryside.
History at Abbeytown
Leaving Wigton, the bus passes through Waverbridge before reaching a true historical highlight: Abbeytown.
Keep your eyes peeled for the imposing Holme Cultram Abbey. Founded in 1150 by Cistercian monks, this was once one of the most powerful religious sites in the north. Despite Scottish raids and the Dissolution of the Monasteries, the nave survives as the parish church. It is a “Solway gem” and well worth a stop if you love history.
The final stretch to the sea
After passing the small settlement of Calvo, the air begins to taste salty. You have arrived in Silloth.
Silloth is the jewel of this route. Laid out in the 1860s, it retains its Victorian elegance with wide, cobbled streets and the magnificent “Green”—one of the largest village greens in England. The bus stops right near the seafront, offering immediate access to the promenade. On a clear day, the views across the Solway Firth to Criffel and the Scottish hills are simply breathtaking.
For those who want to see the very end of the line, some services continue a little further north to Skinburness. This quiet residential area was originally intended to be a major port, but nature had other ideas; today, it’s a peaceful spot for birdwatching and enjoying the solitude of the coast.
When does the route run?
The 400 service is operated by Stagecoach and runs Monday to Saturday.
It is important to note that there is generally no Sunday or Bank Holiday service on this route, so please plan your weekend trips accordingly.
Service frequency
During the week, the bus runs roughly every hour to 90 minutes during the daytime. The journey from Carlisle to Silloth takes approximately one hour and ten minutes, making it an easy duration for a day trip without feeling like you are stuck on a bus for too long.
Value for money
Travel on this route is currently exceptional value. The “Bus Fare Cap Grant” in England means that a single journey to Silloth costs just £2 (valid until at least the end of 2024).
If you plan to hop on and off—perhaps stopping in Wigton for lunch and then continuing to Abbeytown—a DayRider ticket might offer more flexibility. For families or groups, the North West Explorer ticket allows unlimited travel on Stagecoach buses across Cumbria and beyond, which is perfect if you are connecting from the Lake District.
Top tips for the journey
- Sit on the right: If you are travelling from Carlisle towards Silloth, sitting on the right-hand side of the bus can give you the best initial glimpses of the sea as you approach the coast, though the landscape is generally flat and open on both sides.
- Check the return time: Since the service doesn’t run late into the night, make sure you know when the last bus leaves Silloth (usually in the early evening) to avoid a costly taxi ride back to Carlisle.
- Dress for the coast: Silloth is famous for its bracing sea air. Even on a sunny day, it can be breezy on the promenade, so bring a layer.
- Bring a camera: The sunsets at Silloth are legendary. If you catch the late afternoon bus in winter, you might be treated to a spectacular sky over Scotland.
Planning a day out on route 400
Here is a suggested itinerary for a relaxed day:
- 10:00 AM: Catch the bus from Carlisle Bus Station.
- 10:35 AM: Hop off in Wigton. Explore the market town, grab a pastry from a local bakery, and see the memorial fountain.
- 11:50 AM: Catch the next bus towards the coast.
- 12:15 PM: Arrive in Silloth. Walk along the famous Green, visit the discovery centre, or grab fish and chips to eat on a bench overlooking the Solway Firth.

- 04:00 PM: Head back to the bus stop for a comfortable ride back to Carlisle, arriving in time for dinner.
Year-round appeal
While Silloth is glorious in the summer with its “Splash Pad” for children and events on the Green, this route has a distinct charm in the cooler months. The Solway Coast is dramatic in winter; the skies are huge, and the migratory birds (including thousands of geese) make the salt marshes a nature lover’s paradise. Just wrap up warm, and you will find the solitude of the 400 route a refreshing escape from the modern world.
