Wonderful small village between Zumaia and Zarautz, careful in passing inside the city centre as there is loads of people, but beautiful buildings and roads going up the old town

It is a greenway for all audiences, in which there are many bridges and tunnels. The last time it was cut off and I couldn't complete it due to a landslide.
