This was a message from Caroline:
Hello, I can take people from St Jean to Roncesvalles. I do it every day, generally in the morning. The price depends on how many people I pick up. So it is 9 euros per person if I have at least 3 people. But if you are alone, it is 27 euros, if you are 2, it is 13.5 euros for each one and if you are 3 or more, it will be 9 for each one. And I try to make group with different people who call me. I hope you understand, because my English is not so marvellous!!
For bags, it is 8 euros for each day and I go to Logrono, 7 days walking or more (depends on people) from Saint Jean Pied de Port. If you are more people it will be less expensive.
