Hondarribia Patron Saint Celebration and General Questions

"First of all, I am having some trouble finding a good list or source of the must sees/dos of a day-trip to Hondarribia? "

Hondarribia is very small. Even in the larger places like San Sebastian and Bayonne, if you're looking for "must sees and dos," the Basque country is going to disappoint or frustrate (as it did to me until I realized this). For details of my experiences there, here's my long trip report: https://community.ricksteves.com/travel-forum/trip-reports/basque-country-trip-report-bayonne-san-sebastian-vitoria-gasteiz-and-bilbao-may-2017

Hondarribia has two main areas, the upper town (very pretty to walk around) and the lower town (near the water, also pretty). But did I mention how small it is? It can be seen fully in a few hours, and you don't need an "organized walk" to do so. I enjoyed it for what it was, but if you're looking for a place with "turnstile attractions" (Rick's wonderful phrase), you're going to be unhappy. Again, that's true of San Sebastian as well. Vitoria and Bilbao have much more to "do" than the rest of the Basque country.

I can't help with your other questions.

While some restaurants may be closed, if there’s a festival going on, there will be plenty of places to get food. As for the town’s highlights, to me, it’s the historic center up on the hill by the Plaza de Armas, and the medieval wall. Other than those, it’s just walking around the lower town and by the beach. If you don’t want to walk up the hill, there is an elevator on Sabin Arana Goiri Kalea. It lets you off just behind the Parador.

Hondarribia is a small city of 10,000, not a village.
The medieval town is at the top and the fisherman’s village is at the bottom. We spent a week there and loved it. Their tapas restaurants win awards.
There is s tiny ferry that crosses the river to France for a small charge.

Thank you for the responses so far.

I apologize if I gave off the wrong impression. I am definitely not looking for "turnstile" types of attractions. I was more so just looking for any sort of specific recommendations as to fill a few hours there. For instance, are there any specific historic buildings or sites I should make sure to pay attention to while walking through the old city area?

I can’t think of any specific building to visit. The town just isn’t that big. You can spend an hour or so walking the old town and the walls, then spend a couple hours in the lower town walking along San Pedro Kalea and down by the beach. The interior of the Parador is pretty, but unless you’re a guest, you can’t see most of it. I spent a couple days there last year and walking around is the big attraction.

Jaimeelsabio, above, nailed it. Just walk around the upper town and the lower town - those two areas are your "targets," not any individual buildings or more specific sights.

In places like Hondarribia, my practice is to walk every street in the historic district; as noted, Hondarribia has two such areas. I don't remember how long that took me in Hondarribia, but I suspect it was closer to 4 hours than 2, but I probably grabbed something to eat along the way. One thing I'll warn you about is that as of 2016 the tourist office was quite a walk from the bus stop--down past the fishermen's district. I'm always looking for a paper map, and it took me quite a while to acquire one. I'd suggest printing a map off the internet and taking it with you unless you want to use something electronic.

Speaking of the Tourist Office, this link seems to be a good start: http://www.euskoguide.com/places-basque-country/spain/hondarribia-tourism/.

Already using that link!

Thank you all.
