After Lezama, the first village on the Camino is Zamudio. You will get there through the national road N-637, where you will walk past the church of San Martín and the 15th–century Torre Malpica. Once you reach the church, the path continues to your left on a detour going through an industrial park and then climbing Mount Avril.
From its Southern slope, you start descending towards Bilbao, with nice views over the city. Bilbao is the largest city in Euskadi, the Basque Country, and its economic capital. It is also the most important city on the Northern Way.
In recent decades, it has witnessed an important transformation both in terms of its citizen-friendliness and aesthetics, after the decline of the steelworks. Some examples of this transformation are the metro and the Guggenheim Museum, an architectural symbol of the new Bilbao.
