It is also possible to fish salmon in the famous Lærdalsøyri.
The Lærdalselva is a major large salmon river and among the leading angling rivers in Norway. Salmons swim upstream for about 22 kilometers into the river before being stopped by the Sjurhaugfossen waterfall, and there may be salmons in the lower parts as early as mid-May. Sea trouts swim upstream from the end of July.
Salmons can be over 20 kg and up to 25 kg, while the largest trout caught weighed 12 kg. Royal personalities and other celebrities have been fishing in the river for the last 100 years. The norwegian King Harald V has been fishing there regularly since the 1950s. The tradition of angling started with British lords in the 1850s.
