Hazas is the center of the Liendo area, a collection of towns spread out across this broad valley. As such it has most of the services you need. The Iglesia de Nuestra Señora de la Asunción stands opposite the albergue.
From the albergue the camino climbs up to join the N-634, turning left to follow it a short distance. When it splits the official camino turns left to leave the main road and descend to Tarrueza. You can alternatively keep on the N-634 on a shorter course to Laredo; this option will rejoin the official camino at a large junction.
