The large plantations to your left as you walk through Las Casas are often mistaken for vineyards. In fact grapes grow poorly in this climate and these are kiwi.
After crossing the bridge into Cornellana there is a sign indicating a trail to your left. This option takes you directly to the albergue without first passing through town. It is the same distance.
There is a large traffic interchange at the end of Las Casas, in the hamlet of La Rodriga. The camino keeps to the left and towards the river. In the summer months there may be a bar open in the park alongside the river.
