Lake

Weather…

Pielinen is the fourth largest lake in Finland, covering an area of approximately 894 square kilometers in the North Karelia region. The lake stretches about 120 kilometers in length, bordered by the municipalities of Joensuu, Lieksa, Nurmes, and Juuka. Geographically, it is characterized by a diverse shoreline and over 1,200 islands, with Paalasmaa being the highest inhabited inland island in the country. On its western shore lies the famous Koli National Park, where the quartzite peaks offer a panoramic view officially recognized as Finland's national landscape. The lake was formed after the last ice age roughly 10,000 years ago and currently drains through the Pielisjoki river into Lake Pyhäselkä. Historically, Pielinen served as a crucial transport route for the timber industry and is now a premier destination for nature tourism and fishing in Eastern Finland.

Terrain & paths

The landscape around Pielinen contrasts dramatically, with the western shores being relatively flat and the eastern shores featuring steep, heavily forested hills and prominent rocky viewpoints.

Parking

Dedicated parking areas are widely available at major trailheads and national park visitor centers. It is strongly recommended to use official lots to avoid blocking narrow rural forest roads.

Safety

When hiking the elevated eastern shores, always stay on marked trails and away from steep cliff edges. Weather can change rapidly in the hills, bringing unexpected rain or fog that reduces visibility.
