There is no universal Icelandic fishing licence — rights are water-specific and rod numbers strictly controlled. Víðidalsá is a classic north Iceland big-fish river — the average salmon an unusually heavy four kilos, ten-kilo fish landed every year — fished by just eight rods over four 2-rod beats, three on the main river and the fourth on the spawning tributary Fitjá, across roughly 38 km and a hundred-plus named pools. Low rods over long water make availability scarce and access a multi-day lodge package, not a day ticket; 'where you fish' is assigned by rotation. Confirm the current eight-rod / four-beat structure, the role of Fitjá and the rotation map before relying on this.
