Starting out from Arroeta, the route crosses the Zamudio Technology Park and gains altitude little by little towards the hills of Berreaga-Urrusti-Gaztelumendi, passing alongside the chapel of San Bartolomé. Among the forests and plantations of these hills, the fortifications and trenches built during the Spanish Civil War between 1936 and 1937 are conserved as part of the Iron Ring defensive line. The route continues after a stretch along the hill range with a descent towards Fulla and, running between meadows, copses and farmsteads, returns to Zamudio town centre.
