About this water

The upper Pisuerga flows through dramatic Cantabrian mountain terrain — 50 km of pristine freestone with prolific brown trout. Limestone geology ensures exceptional clarity demanding precise presentation. Pocket-water in upper reaches transitions to productive pools and runs downstream. Excellent Baetis and Ephemerella hatches late March–July reward technical dry-fly work.
