4. Arantzazu - Etxegarate

Aránzazu embodies the Basque contribution to the artistic avant-gardes of the 20th century, while at the same time being an important cultural production centre. It was the birthplace of euskara batua (standard Basque), among other things. From Aránzazu we ascend to the fields of Urbia. The megaliths and huts of the area show that it has been inhabited for a long time. Having a broth to recharge your batteries in the Urbia inn is a great idea. From Olza, we will reach the San Adrián pass, a historic communication route with Castilla which saw countless events and comings and goings from the Roman era and which crosses Aizkorri from one side to the other. Continuing along the route, through Añabaso, we approach the border between Navarra, Álava and Gipuzkoa. Etxegarate, the end of the stage, awaits.
