About this water

The Aragón Subordán flows through the dramatic Hecho valley before joining the main Aragón. Limestone gorge creates clear, alkaline freestone water with strong wild-trout populations. The Oza tributary is a classic high-mountain stream ideal for technical dry-fly work. Good wading required.
