Getting from Biarritz to St Jean

Hi there,

I'm leaving to begin the Camino on Sunday morning and was just wondering if anybody would be able to help me out.

My flight arrives in Biarritz at around 3pm on Sunday and I know that there's a limited bus service to St Jean on Sundays.

Does anyone know how much a taxi might cost or if I should chance getting the last bus - whatever time it might be at! Any ideas? Any links to bus/train timetables would be greatly appreciated.

Thanks
