Oulanka National Park is a unique and versatile combination of northern, southern and eastern nature. The park is part of the European-wide Natura 2000 network due to its valuable natural features. In the valleys of the park, there are lush herb-rich forests and on the hill slopes, pine heathlands. Wild rivers have been carving the landscape, and the longest free-flowing rivers in Finland, the Oulanka and Kitka Rivers, flow in the park.
