You will have to bring warm clothes (trousers, sweater, socks, closed shoes, rain clothes) and light ones (skirts or shorts, t-shirts, open shoes) because the weather can change very suddenly in Brittany. You can literally experience all four seasons in one day! Please also take with you working clothes, gloves and shoes in addition to your swimsuit. Bring a warm sleeping bag and an insulated camping mat as nights are sometimes fresh and wet.
You can bring board games, a musical instrument or anything else from your region/country that you would like to share with the group.
