I lived for 2 years in St Jean de Luz in the french Basque country, 10 mins away from this part of the sea, and always hoped to see (not surf!) the Belharra wave first hand. Makes me homesick! It's just so beautiful there. You have the mountains and the sea right next to each other (why am I in London...wail
)
Believe this year's Belharra was up to 20m high.
