A western Gipuzkoa trout river offering clear water and productive brown trout habitat across 52 km. While historically significant for salmon, contemporary stocks are lower, making it a specialist trout destination. Spate character with rapid 4-hour response ensures good winter and spring trout fishing. Mixed geology creates varied pool and run habitat for resident and migratory sea trout (though numbers modest). Moorland and woodland catchment maintains excellent water quality and cool temperatures. Less crowded than salmon-focused neighbours, appealing to those seeking trout fishing without permit complexity. Predominantly wild habitat with water-level fluctuations requiring adaptive tactics.
