The marked way through Zarautz is along the Nafarroa Kalea, about two blocks from the waterfront and parallel to it. As an alternate, you can turn right towards the beach and follow it to the end of town.
Leaving Zarautz can be a confusing affair and the local information office doesn’t do much to clarify matters.
There are two options out of town:
Option 1: The Official Camino to upper Getaria - 5.2
The official camino through the hillside; this option also splits so read ahead to find out more. At the end of the beach or road turn left (south, away from the sea) onto San Inazio Kalea. Keep to the right-hand side and continue a short distance, keeping an eye out for the small road that ramps up to the right and nearly parallel to San Inazio. That road is the one you want, and it will take you upwards.
Near the top, there are signs for the Ermita de Santa Barbara (and an excellent view back east). Not far from the Ermita the camino leaves the road along a path to the right which offers views of the sea. A short distance down this trail the camino joins a different paved road and quickly arrives at a junction. At this point, you have the option of bypassing Getaria entirely. Keep straight for Getaria, or turn sharply left to follow the GR-121. This second option rejoins the first slightly beyond Askizu.
Option 2: The road to lower Getaria - 4.1
The alternate road route along the N-634 coastal road to Getaria. At the end of the Nafarroa Kalea or the end of the beach, turn right and follow the pedestrian path adjacent to the road as it hugs the coastline all the way to Getaria. Simple and straightforward.
