Cost to Drive to Devon UK
Driving to Devon can look simple if you only count fuel, but the real cost of a day trip, weekend break or week-long holiday depends heavily on parking, the season and how busy the roads are.
Use this page to estimate your fuel cost, check the real parking and seasonal costs specific to Devon, and plan a trip that doesn’t cost more than you expected.
The simple answer
The fuel cost of driving to Devon depends on your starting distance, fuel price and MPG. A 100-mile trip in a 45 MPG petrol car at £1.60 per litre costs about £16 in fuel each way, or about £32 return.
That is not the full cost. Local town parking varies widely, but tiered charges are typical – for example around £1.70 for up to 1 hour rising to roughly £13.60 for 24 hours at Mid Devon car parks, with coastal towns often pricier in summer. Peak season and weekends can also mean significantly more traffic and busier car parks than an off-peak weekday visit.

Extra costs of driving to Devon
These are the costs that often make the real trip more expensive than the fuel estimate.
Expect tiered hourly rates rising toward £13-14 for a full day at many Devon town car parks, with coastal towns often charging more in summer.
The M5, A38 and A30 all converge near Exeter, and congestion is common around Junctions 29-30 and on the A30/A38 approaches, especially on peak summer Saturdays.
Most trips need the cost of getting home included, not just the outward journey.
Tyres, brakes, servicing and depreciation still matter on longer journeys.
Entry fees, equipment hire or food and drink can add up quickly on a day out.
Almost every route into Devon passes near Exeter, where the M5, A38 and A30 meet – this is consistently where delays build first.
Devon trip checklist before you drive
Check these before deciding your visit is going to cost what you expect.
Where will you park?
Popular spots fill up fast on nice days — have a backup car park in mind.
Is it peak season?
School holidays and summer weekends mean higher prices and much busier roads.
How many people are travelling?
Driving often looks better when several passengers split the same fuel and parking cost.
How long are you staying?
A day-ticket or weekly parking pass can be cheaper than paying by the hour if you’re staying a while.
Cost to drive to Devon by trip type
The same mileage can feel cheap or expensive depending on the kind of trip you’re planning.
Dartmoor day trip
National Park car parks are genuinely cheap for a full day out – Widecombe-in-the-Moor runs about £2.10-£2.20 for all-day parking, well below most coastal town rates.
Weekend break
Check whether your accommodation includes parking before assuming you’ll need a paid car park too.
Week-long holiday
Consider GWR into Exeter St David’s instead of driving both ways from London – up to twice hourly, about 2h16, from £19.45 if booked ahead.
Dartmoor walking trip
Private Dartmoor parking runs from about £0.90 an hour, or £48.50 a month if you’re a regular visitor – worth it if you’re walking often rather than paying National Park day rates each time.
