We've camped in the south of France and Spain and Germany over the years in these months and always had a great time (even sometimes with 6 teenagers +2 dogs )
We tend to drive, then camp a few days enjoy/explore and drive on.
This year we were thinking of heading to Nordic places instead.
We have a mini-caravan now (think old VW campervan size) and an awning for putting up if we stay longer somewhere.
I think we will need to pack a wine lake to take with us but don't know much else about Sweden/Denmark/Norway.
Do you have any advice?
Is the weather terrible at this time of year?
Are there clouds of biting insects to face?
Is there anywhere we should make sure to see?
Do all the campsites close in Sept?
