though I'm not from France and you probably got the one or other suggestion via
mail - here's two more: I know these are tourist areas as well - but anyway:
1) Brittany (Bretagne) offers lots of beautiful seaside scenery and also gives
you a chance to go swimming in refreshingly cool water ;-)
2) Of course, the Côte d'Azur is also worth a visit. Again beautiful seaside
scenery - and the water a bit warmer, as it is the Mediterranean and not the
Atlantic. If you travel westward you get to Provence, which is also renowned for
its beautiful nature.
Hope you have a good time!
