T passed through here a few years ago, just a fleeting stop and it’s a must see destination on the North Coast of spain, and within spitting distance of France.  The camper stop was full up to the nines, so we did an emergency google for local campsites and found one only a couple of km away down a very narrow & windy rural lane.  We didn’t know what to expect although the photos on google looked good. It turned out that we aced it. It’s the end of season so the campsite was almost deserted. There were three other campervans and the rest of the campsite was pretty empty.  We got the swimming pool to ourselves too!
The 15€ discounted ACSI rate per night included a minibus into the town, so it worked out cheaper than many stopovers that we have done in the last month. Throw in the pool, sauna and it was a bargain.
We spent the next day exploring San Sebastian, going up the funicular to enjoy the view and promenading along the seafront with the locals. Lunch by the sea.
That night and following day we had proper rain for almost the first time since we left home and howling wind, so it a was a maintenance day – probably well needed!
