Across the bay from Hendaye and joining on the practical town of Irun, Honarribia is a charming tranquil little resort & port. However the battered town walls reveal a dark past of conflict between the kingdoms of France, Castille and Navarre.
It's a bit nippy in winter and very busy in August with French holidaymakers so Spring and Autumn are perfect.
To help appreciate the town, I'd recommend getting a copy of A Basque Diary by Alex Hallett which recounts her time living in Hondarribia.

pretty walled town

Station stroll ideas
It's perfectly possible to walk to and around Honarribia from Irun Eustotren station or even Hendaye station, but only really worth the 5km of shoe leather if you like looking at airport runways.
The Honarribia app is a good guide to help you navigate around the town:
