Kolis nature and scenery change every season - and they captivate visitors all year round. This area, with the oldest bedrock in Europe, has been around for three billion years, and is a unique destination at any time of the year.
Winter lasts for a long time in Koli. The ski slopes in Koli face east and north which guarantees that you can do downhill skiing long into spring. When the snow melts, the steep hills of Koli are full with the sound of burbling and gurgling water! Nature wakes up and birdsong dawn chorus concerts are in full swing. At least 4 078 species have been observed in the Koli National Park, more than in any other Finnish National Park. In April and May, companies, organisations and societies come to Koli to hold meetings and make plans. Small meetings can be held, for example, in a cozy wooden hut over a campfire meal. For bigger gatherings the auditorium in the Nature Centre Ukko seats up to 200 people
In June, the day is at its longest, and the flower meadows in the Koli National Park are in full bloom. Through summer until late autumn you can enjoy the cooling water of Lake Pielinen and its many islands and sandy beaches. In the Ruunaa Hiking Area you can experience thrilling whitewater rafting. People on summer holiday come to stay in the cottages in the region, barbecue, go to sauna and enjoy hiking and horseback riding. In the Koli National Park sheep, horses and kyyttö, the traditional Eastern Finncattle cows, graze in the cultural landscape and bring joy to the visitors. Summer in Koli is also a cultural summer! Lieksa Brass Week, Monola Festival, Theatre Koli, Koli's Outdoor Week and Pielinen Soi Festival provide joyful experiences – something to remember long after the holiday is over.
