The official language in Brittany and Rennes is French. The Breton language is still very much alive in the region. In the part of Haute-Bretagne where Rennes is located, the traditional language is called Gallo. If you don’t speak French, Breton, you’ll encounter plenty of English speakers due to the large student population and the region’s cultural proximity to Great Britain. Last but not least, at the Tourist Office, our travel consultants can answer your questions in English, German or Spanish.
