A day full of short, sharp climbs. From Zarautz you follow the coast to Getaria and on to Zumaia. After that the path becomes a series of hills, up and down again and again, with the sea in the distance. There is no single long climb. That is exactly why the fatigue creeps up on you.
All in all, it adds up to more than 800 metres of climbing. You will feel it mostly in your knees on the descents. Take your time, because you will be on the move for over 7 hours. On the final stretch you descend to Deba, at the mouth of the river. You walk between the houses to the centre, with the beach just behind them. Rucksack off, boots off.
