Gap Travel France
A gap year spent in France will enhance your cv provided you do something worthwhile, like studying French or something like wine growing or architecture. No visa issues for Brits but also not a lot well paying jobs around either, so consider your gap plans carefully before deciding on France.
You could try for a job in tourism in the south of France or in the French Alps, but these go fast as they are very sought after among gap travellers, so apply early.
