The best things that you can take with you is a swimming costume, cream, ball & racquet, books...and an enormous feel like to enjoy a nice travel and stay in the border of the Neuchatel Lake. (like me in the picture!!!!!!) Fresh clothes in general during the day & for night a coat, weather is colder! Everything you can find it in the campsite and most important cities. No problems to find re-charge digital camera or to obtain right batteries Everything that you can take like when you go to the beach. Mosquito repellent!
