Brittany, is it worth visiting?
 

We have 3 or 4 days to spend in late August, before returning to England. One option is to take the ferry from Roscoff to Plymouth and visit Brittany. Is it worth the trip? The other option is add on to our two weeks in Paris. Your suggestions would be most appreciated.

Britanny is a nice place to visit, should you like wild (and beautiful) sea landscapes. Villages are also very pretty and you will find many remains of megalithic times.
