Short route following Rubionzo river, located between Saro and Villacarriedo, mainly populated by Atlantic forests like a small oak grove and reminders of the hydroelectric activity since 18th century.

Abionzo is a vantage point above Pisueña highwaters. We can appreciate from here the river terrace between Tezanos and Santibáñez. From here, we will walk through cultivated terraces. Later, we will reach mount Zarrizuela, one of the best preserved local forests.

Further along our journey, we find the mill of Rubionzo, which still preserves its original machinery, derivation channel and a curious stone bridge.

The Rubiozo river has some good examples of pre-industrial heritage linked to hydroelectric activities in the region. The power plants there produced a continuous current, which gave energy to the town.

In the square of Llerana, next to the bridge is the old forge of La Magdalena, which belonged to Sir Alonso de Obregón y Arce in the first half of 17th century. We can also see here a good example of  a manor house that belonged to Count of La Valenciana, knight of Carlos III who became rich from a silver mine in Mexico.

We return along the same path, in about one and a half hours of pleasant walking in any season.

Returning to Abionzo, we can see Pisueña’s high valley, where we can appreciate some popular buildings of interest. The neighbourhood of Concejero, east of the town, is surely one of those who maintain the rural character in the municipality.
