The town of Zerain is located in the Gipuzkoan region known as Goierri. Situated just to the north of the Aizkorri Range, it is a mountainous area right in the heart of the Basque Country.
Just one hour from Bilbao, San Sebastián, Vitoria and Pamplona, the best way to reach Zerain - which offers some of Gipuzkoa's most stunning views - is along the N I. Turn off at Idiazabal, and head towards Segura along the GI 2637. After passing this medieval town, turn right onto the GI 3520 at the Zubiberri junction, and continue on until you reach your destination.
