River Kymijoki

 

A canoe trip down the river Kymijoki is a true wilderness adventure.  Especially the portion from Susikoski to Pernoo and Hirvivuolle is for the most part in its natural state. Paddlers can see many rare birds there, for example the grey heron which nests numerously in this area. Big hawks are common too.  The river flows through Valkmusa National Park, a typical example of peatland in southeastern Finland. In Valkmusa you may see an osprey gliding above the river or dashing into the water for fish. 

The largest part of river Kymijoki belongs to Natura 2000 nature protection project. The great free-flowing rapids are protected by law, too. The drainage basin of the Kymijoki water system covers 37 107 square kilometres which is 11 percent of the whole area of Finland and the lake depth percentage is 19,7. The Kymijoki is the fourth biggest river in Finland as regards to the amount of flowing water. The river is divided into two branches below the Kultaankoski rapids where the main stream splits into eastern Pernoo branch and western Hirvikoski branch. The two chief branches are divided into altogether five smaller streams before reaching the Baltic Sea.
