About this water

Two sin muerte tramos on the main river: upper (Tornavacas, piscina natural to Puente Navarro) and middle (Jerte and Cabezuela del Valle). Four tributary gargantas also sin muerte: Garganta San Martín, Garganta Becedas (both Tornavacas), Garganta Nogaleda (Navaconcejo), Garganta de la Luz/Las Monjas (Cabezuela). All steep granitic mountain streams — pocket water, plunge pools, fast boulder runs. Wild browns under catch-and-release, barbless single hooks only. Season: 3rd Sunday March–31 July. Tight-line nymphing, small nymphs, tiny dries.
