We're walking the Camino Frances and then want to spread some of Dad's ashes at Finisterre. Short on time, we want to find an accommodating taxi driver for round trip from Cathederal to the coast to the Santiago airport on 5-30. We want to make reservation ahead of time. Do you have knowledge of reliable, accommodating taxi driver/company???
You might find some answers asking this on one of the Camino forums or FB pages. Are you on any of those?
