Relocation to Biarritz (France) - getting in touch with British expats


I'm from London and planning a relocation to Biarritz (South West of France) after the summer.

Does anyone know if there is a community of British expats in the French Basque Country?

I would love for my son (who's 10) to meet other English speaking kids who share a similar experience of relocation, and to find ways for him to maintain a cultural connection with the UK.

It would be great to hear from anyone who has lived, or lives, in the area, especially parents with young children and teenagers.

Many thanks.
