Camping Les Acacias

Of your two routes I myself would go towards Rennes because it's dual carriageway and toll free. One hour from the ferry port is a respectable site at  Villedieu les Poeles - it was once municipal but was privatised 3 or 4 years ago and upgraded and improved by the new owners. They now call it Camping des Chevaliers de Malte. You can get some food and drinks on site but a short stroll onto the village will give you more choice. 

Camping de la Bord d' Aure at Bayeux is good for an overnight. There's a McDonalds nearby and various restaurants within a km of the site.

Falaise.

Sorry....camping municipal at Falaise. Directly under William Conquerers Castle. Nice walk into the town. Supermarketss and petrol nearby. English spoken.

Never used it but friends strongly recommend the Falaise site.

This is our first time in France with a motorhome, having been many times with a caravan, and now we want to be able to enjoy the journey, as well as the stays, so no Aires please!

Why no Aires, unless you try them you will never know, picture of a couple we have stayed on attached...

MH are completely different to caravans and are meant for touring IMHO so make the journey part of the adventure, being able to stop in towns and villages with all the facilities is great.

totally agree with Michael, as will Keith of course....

some aires arent what many think...

Good photos from two contributors. Thank you.

But are they an hour from Caen ferryport with restaurant and bar on site -  which is what the OP asked for ? 

like michael, my quick post was just to illustrate that not all 'aires' are the sort of places a former caravanner wouldnt set foot..

however, back to the OP and Avranches has an aire behind the Jardin des Plantes, is just an hour away from Caen and gives strolling access to this lovely hilltop town....

ok, this is just a dedicated MH car park with facilities, but for an overnight in a wonderful town with the Jardins and the Eglise Notre Dame des Champs D'Avranches a couple of hundred metres away, certainly worth a try.

also, terrific restaurants, views across the Baie and, of course, the aire is free

a great first timer to illustrate just how easy it is to roam and park (usually for free) close to wonderful French towns/villages, with no booking and generally easy walking to Centre Ville.
