Regardless of the season in Brittany, you should bring at least one warm outfit (pants, sweater, socks, closed-toe shoes, rain gear) and one light outfit (skirt or shorts, t-shirt, open-toe shoes). Here, it's said that all four seasons can be experienced in one day! Also, remember to bring work clothes and closed shoes, a swimsuit for swimming. Nights can be chilly, so bring a good, warm sleeping bag and an insulated sleeping mat.
Social events will be organised together with your campleaders. If you'd like to share a little piece of your culture (recipes, traditional stories, unusual objects, music, etc.), don't hesitate to take something with you !
The last day is dedicated to departure, usually in the morning.
