We're planning on going to France again this year for holiday, constrained to going in school holidays. Last year we went to Brittany but it was a nightmare finding a beach which was suitable for sandcastle building and allowed dogs. Can anyone recommend an area to go to? We are happy to go in land and I think I read somewhere that dogs weren't allowed in some French national parks, is that true? Anyone able to advise on both beach areas and national parks. Thanks.
