Looking for the most beautiful waterfalls in Finland? The most popular hiking trail (Karhunkierros Trail, The Bear's Ring) is also located here In Oulanka National Park and the one to go to, if you are looking for a challenging, but rewarding hike. My recommendations for visit are Myllykoski, Kiutaköngäs, Jyrävä, and Oulanka Visitor Centre. There is a reason why professional nature photographers keep coming back here - this national park is so unique!
