Have you tried Google maps ? Shows about 6 hour drive
Google maps are always optimistic on time, sometimes laughably so. When are you travelling? You need to get past both the Birmingham and the London conurbations, both of which have really dreadful traffic in weekday rush hours.
Thanks for your reply we should be leaving Holyhead around 11am so maybe mid afternoon
You really need to look at traffic conditions on the day and try to time it to avoid rush hours and be prepared to take an alternative route. Maybe the M40 instead of the M1 and go anti clockwise around the M25 rather than take the Dartford crossing.
I would give it at least 8 hours with stops.
Thanks for your reply ...very helpful
I am doing this journey in July, have you been yet, how did you get on, which route did you take, i would be interested in how long it took, thanks.
What part of France are you going to? Do you need to travel from Folkestone? I was wondering if perhaps one of the ports on the South Coast would be more convenient - you would be able to give London a wide berth that way.
There is a ferry from Cork to Roscoff in France if that is any use.
Sorry to make the journey sound worse but I assume you will take the A5 after leaving Anglesey. I have only done bits of this route but whilst the scenery is great it is not a fast road so allow plenty of time.
Then you hit the M6/5 to get to the M40 which can be 70mph or walking pace.
Yes we have been already whilst France was superb I wouldn't recommend the driving from Holyhead to Folkestone between the roadworks,accidents and general traffic around London this place is just one giant car park we only took this route because I'm unable to fly due to a disability the journey took 8-9 hours including stops if you are going get yourself a good sat nav and keep your cool there are some very strange driving manoeuvres going on ....good luck
