About this water

River flowing through the Tri-City region (Gdańsk/Gdynia/Sopot), grayling, brown trout, and sea trout in forest-backed water. Close to major urban centres yet maintaining real wild character. A rare city-proximate river that doesn't read as filler—the Reda has genuine fly fishing credentials.
