About this water

Catalan mountain stream flowing from the Cerdagne plateau. Freestone with wild trout and grayling in cold, clear water. Short season — snowmelt-dependent. Fish from June onward when water clears and warms. High altitude, technical pocket water. Hiking-in country; expect pristine conditions and few anglers. Check regional regulations for protected stretches.
