It's hard do describe how beautiful is Norway to go kayaking. This small country has an incredible number of runs, one close to the other. You can travel from river to river without drive for more than 45 min. Norway is famous for the rain and snow, so the river are generally quite full of water. Every river can be run with very different water flows. The best season start with March-June till the end of August. Expert kayakers can find many class V and VI rivers (Telemark and Voss), while is also possible to find class III and IV rivers especially in the Sjoa area.
