San Isidro, the patron of the town, is celebrated on the 15th of May.
Larrabetzu is one of the most outspoken villages in the Basque fight for independence. The city was a key location in the line of defense known as the Iron Belt. The hillsides here are criss-crossed with trenches and fortified bunkers designed to defend against the capture of Bilbao by the fascists in 1936. The efforts were unsuccessful, but the pro-Basque vision never waned. The city remains painted and plastered with graffiti and banners proclaiming independence for the Basque country and liberty for resistance members currently imprisoned.
The camino turns right at the entrance to Larrabetzu, leaving the main road behind. In town it turns right and begins to follow a different road directly to Lezama.
