Bidasoa, Irun — Area Guide & Where to Stay
Bidasoa names the river joining the Cantabrian Sea between Hendaye and Hondarribia, and the quarter of Irun that carries it.
About Bidasoa
Where to stay in Bidasoa
Where you base yourself shapes the visit — here's the character of each area.
Arma Plaza and the Castle of Carlos V hold the rooms worth crossing the Bidasoa for, and they stand in Hondarribia rather than in the quarter of Irun that shares the river's name. Irun keeps the practical beds. Casa Echeveste, listed as the Hotel Obispo, shows how the old houses of Hondarribia have been turned to lodging, while the Bidasoa side of Irun runs to apartments within reach of both Spain and France.
About Bidasoa
What are the main landmarks in Bidasoa?
Hondarribia holds the register. The Castle of Carlos V is the heaviest name on it, with the Church of Santa María del Manzano and the Church of Santa María Magdalena carrying the parish work, and Palacio Zuloaga, Ramery jauregia and Casa de Casadevante lined up among the noble houses. Arma Plaza is the address that repeats.
Eight of the listed houses stand on that square alone, and Casa de Juana la Loca, Casa Mugaretenea and the addresses on Nagusia carry the rest of the old town's registered fabric.
What is the history of Bidasoa?
The name arrives late in the river's course. Streams merging near Erratzu make the water, and only downstream of Oronoz-Mugairi in Navarre does the record call it the Bidasoa, with the Baztan stream rising off the mount Autza counted as the source. Hondarribia wrote the rest.
Its walled houses, Casa de Casadevante, Casa Mugaretenea, Ramery jauregia, and the Castle of Carlos V accumulated at the mouth of the Bidasoa, opposite Hendaye on the Cantabrian Sea.
Where is Bidasoa?
Gathered from streams near Erratzu and named below Oronoz-Mugairi in Navarre, the Bidasoa runs down to the Cantabrian Sea past Irun.
