We are planning our trip for the summer of 2014 and I'm trying to decide between August and July.
The advantage of July is that there is a renaissance faire in Dinan that looks really interesting. My family loves these types of faires in the US and so we're really interested in going to this one. I do worry that it will be absurdly overcrowded.
I usually prefer to travel in late August, because airfare is significantly cheaper, and the weather tends to be a bit milder. We live in NY state, so my son is still on summer holiday - most of the US is back to school before the last week of August. We loved Paris in August this past year - there were no crowds, and we had no line at the Louvre.
So what are the pros and cons of July vs August in Brittany?
My family would like to see Dinan (if we don't go to the ren faire, we'll just go for market day), a megalith or two and the ocean. We'll also wander over to Mont st Michel and a quick jaunt through the Loire valley on our way back to Paris. We're thinking our trip will be about two weeks. Thanks so much!!
