Like hundreds of other young people of all countries who take part in our language courses, you can make the most of your holidays by studying French in an interesting way and, at the same time, discover one of France’s most beautiful areas—Nice!

Our summer course lasts 3 weeks in July and August. You’re welcome to come at any time between July and August 6.You can choose to stay at a host family, but we suggest you stay at our international summer camp. It makes it easy to meet other people and make new friends. What’s more, you can have your classes in the same building which is close to the beach! A free bus service brings you to and from classes if you are living in a French host family or enables you to get into the centre of town if you are living at the summer camp.

Whenever you choose to come, we’ll organize short trips, parties, sports and other activities and motivate you to speak French.

Your stay in Nice will therefore not only be an educational one, but also an enjoyable experience. Besides offering you many opportunities to meet other people from different cultures, we will do everything to make sure your stay will be unforgettable!
