In Orio having walked 5 hours in wind and rain today from San Sabastion. Mostbof the way was mud and water often ankle high Question re which route tomorrow. What type paths are on official Camino to zumaia? The costal route along road is possible but could be very wet and windy but is there a path all the way? Also a route which bypasses getaria? Which to chose in this gale as tomorrow also to be fairly bad weather wise also. Thanks in advance
