Quick answer: The core 39-mile Northumberland Coastal Route from Seaton Sluice to Holy Island costs under £8 in fuel — around £6 for an average car. The exceptionally flat terrain lets vehicles hold steady speeds and hit near-optimal MPG, making it one of the UK's cheapest scenic drives. The one trap is the Lindisfarne causeway: miss the tide times and you'll waste fuel idling in a queue. Use the live map above to find the cheapest station along the coast.

How much does it cost to drive the Northumberland Coastal Route?

The core 39-mile route from Seaton Sluice to Holy Island costs under £8 in fuel — about £6 for an average car. The exceptionally flat coastal terrain lets vehicles maintain steady speeds and achieve optimal fuel economy.

This is the opposite of a mountain route: no steep climbs, no hairpins, just gentle roads along one of England's finest coastlines past Bamburgh Castle and Alnwick. If you extend the drive to the fuller 60-mile version taking in more of the coast, it's still excellent value. Enter your own MPG in the calculator below for a precise figure.

Does the Lindisfarne causeway affect fuel consumption?

Yes — indirectly, and it's the one thing that can blow your fuel budget. Miss the tide times for the Lindisfarne causeway and you can be stuck for hours, and leaving the engine idling while you wait for the water to clear wastes fuel and money.

The crossing to Holy Island floods twice a day, and safe crossing times are published in advance. Check them before you set off, arrive within the window, and switch the engine off if you do have to wait. Tick the causeway-idling box in the calculator to see how idling and detours nudge up the cost of an otherwise cheap drive.

Is the A1068 good for fuel economy?

Yes — the A1068 avoids the steep gradients of other UK coastal routes, letting cars cruise efficiently in high gears, which makes it one of the most economical scenic drives in the country.

Where Wales and Scotland punish fuel economy with cliffs and hairpins, Northumberland rewards it with flat, open road. That "flat-terrain advantage" means most cars hit close to their combined MPG figure here. Fill up in the towns — Blyth, Ashington, Alnwick and Berwick-upon-Tweed — where supermarket forecourts are cheapest. Search a postcode like NE66 (Alnwick) on the map above.

Which fuel does your vehicle need? A plain-English guide

The live map above covers all six fuel grades tracked under the GOV.UK Fuel Finder scheme. Here's what each one means — and how to choose at the pump before you set off.

E10 · Standard Unleaded
Unleaded Petrol

The default pump for most petrol cars. Contains up to 10% ethanol. A small number of older or classic cars require E5 — check your handbook before filling.

E5 · Premium Unleaded
Super / Premium Petrol

Higher octane (97–99 RON) and cleaner-burning. Typically 10–20p/litre more expensive. The protected grade for older engines not approved for E10 — and popular with performance cars.

B7 · Standard Diesel
Diesel

The default diesel pump. Contains up to 7% biodiesel. Suitable for all diesel passenger cars, vans and most HGVs. Generally 2–8p/litre cheaper than premium diesel at the same station.

B7 · Premium Diesel
Premium Diesel

Includes detergent and cetane-boosting additives. Sold as BP Ultimate Diesel, Shell V-Power Diesel and similar. Use the Premium Diesel toggle to compare the price gap near you.

B10 Diesel
B10 Diesel

Contains up to 10% FAME biodiesel — higher renewable content than B7. Only suitable for vehicles whose manufacturer explicitly approves B10. Always check your handbook first.

HVO · Renewable Diesel
HVO100 / Hydrotreated Vegetable Oil

Drop-in renewable diesel with up to 90% lower lifecycle carbon than fossil diesel. Compatible with most modern diesels — check your handbook. Use the HVO filter above to find nearby stations.

Where should you refuel on the Northumberland coast?

Fuel is easy to find at the coastal towns, and the flat roads mean you'll use very little of it. Here are the reliable stops along the route.

South Start
Blyth & Ashington

Cheapest supermarket forecourts near Seaton Sluice at the southern end of the route.

Mid-route
Alnwick

The main town on the coast, with supermarket and branded stations — a good central top-up.

Bamburgh
Seahouses

Nearest reliable fuel to Bamburgh Castle and the Farne Islands boats; limited but present.

North End
Berwick-upon-Tweed

The last town before the Scottish border and the nearest fuel to Holy Island — fill up before the causeway.

Two facts most guides skip, both answered here: the flat A1068 is 39 miles of near-optimal fuel economy — genuinely one of the cheapest scenic drives in Britain — but the Lindisfarne causeway can waste fuel through tidal idling if you don't check crossing times.

Fuel & driving

Northumberland's coast by car: castles, quiet roads and the Holy Island tides

By CalculatorDashboard Editorial Team·Updated ·Reviewed ·3 min read

Northumberland's coast is one of the quietest stretches of shoreline in England, and its roads reflect that. The route this calculator uses runs about 39 miles from Seaton Sluice up to Holy Island, following the A1068 and smaller coastal roads past Amble, Alnwick, Seahouses and Bamburgh. Traffic is usually light, the land is gently rolling, and fuel use is low. The one thing that needs real planning is the sea.

The Holy Island causeway

Holy Island, also called Lindisfarne, is reached by a tidal causeway that floods twice a day. Northumberland County Council publishes safe crossing times, and drivers who ignore them are rescued from the causeway every year, often losing their car to seawater. Check the times before you set off, plan your visit around them, and leave the island with time to spare. If you arrive and the causeway is closing, don't try to beat the tide.

The fuel cost of waiting is small, but sitting with the engine running for long periods adds up. A modern car idling might use around 0.8 litres an hour; twenty minutes of idling costs roughly 40p. Switching off while you wait is better for your wallet and for the air in the car park.

A worked cost

For the 39-mile coastal drive in a car averaging 45 mpg, at an illustrative 140p a litre, fuel costs about £5.50. A return trip, with side visits to Bamburgh Castle and the harbour at Seahouses, might double that. It's an inexpensive area to explore by car.

Refuelling and charging

Fill up around Blyth and Ashington in the south, in Alnwick inland, or at Berwick-upon-Tweed in the north. Seahouses is the main stop on the coast itself. Further inland, the A1 has more choice. Electric car drivers will find charging in the larger towns and at some visitor attractions; plan to arrive at Holy Island with enough charge to get back to the mainland and onwards.

Time on the coast

Allow extra time in summer for boat trips to the Farne Islands from Seahouses, which can fill car parks early, and for the narrow lanes around Craster and Low Newton, where parking is limited.

Castles and dunes

Bamburgh Castle and Dunstanburgh Castle are the most famous stops on this coast, along with Alnwick Castle inland. Dunstanburgh can only be reached on foot, with a walk of about a mile and a half from Craster, so plan time for walking rather than driving. Between the castles, long dune-backed beaches at Beadnell and Embleton offer some of the emptiest sands in England, even in summer.

Weather on an exposed coast

The coast faces the North Sea and can be cold and windy at any time of year. Sea fogs, known locally as fret, can roll in quickly on otherwise warm days, cutting visibility on the coastal roads. When the fret comes in, slow down and use dipped headlights, and remember that pedestrians and cyclists on the narrow lanes may be hard to see.

Taking it slowly

Because distances are short and traffic light, it's easy to cover the whole coast in an afternoon. It rewards slower exploration: a couple of days lets you time the Holy Island crossing comfortably, take a boat trip from Seahouses and walk to Dunstanburgh without rushing.

A second example: a weekend circuit

A weekend based in Alnwick, with trips to Holy Island, Bamburgh and Craster and back, might total around 90 miles. In a car averaging 45 mpg at an illustrative 140p a litre, that costs about £13 in fuel, one of the cheapest coastal breaks on this site.

Northumberland coast fuel questions

The core route from Seaton Sluice to Holy Island is about 39 miles; fuller versions taking in more of the coast run to 60 miles or so. It's a short, flat and very fuel-efficient drive that most people spread over a relaxed day with castle and beach stops.
The causeway to Holy Island floods at high tide, and vehicles caught out can be stranded or written off. Always check the published safe crossing times before you go. If you do have to wait for the tide, switch the engine off rather than idling, which wastes fuel and money.
Yes. The A1068 and the coastal roads it links to are notably flat, with none of the steep gradients found on Welsh or Scottish coastal routes. That lets cars cruise efficiently and achieve close to their combined MPG figure, making this a cheap route to drive.
You can, if you leave the engine running. Idling burns roughly half a litre or more of fuel per hour and adds up quickly during a long tidal wait. Plan your crossing around the published times and turn the engine off if you're stationary for more than a minute or two.
Reliable forecourts are in Blyth, Ashington, Alnwick, Seahouses and Berwick-upon-Tweed. Fill up in Berwick before the Holy Island causeway, as there's no fuel on Lindisfarne itself. Use the map above to find the nearest reporting station and today's cheapest price.
For genuine business travel, yes. The HMRC Approved Mileage Allowance Payment is 45p per mile for the first 10,000 business miles in your own car and 25p thereafter; company cars use the quarterly Advisory Fuel Rates. The calculator shows an indicative claim value.
