Lake Oulujärvi

With a surface area of almost 900 m2, Lake Oulujärvi is known as the sea of Kainuu. Lake Oulujärvi is the fourth largest lake in Finland and is geographically situated almost in the middle of Finland. Its beautiful sea-like scenery features the flat plains of Ostrobothnia, the fells of Kainuu, shining golden beaches and bare rocky islands.

Lake Oulujärvi differs from Finland’s other lakes due to its beautiful stretches of open water. Lake Oulujärvi also boasts a large number of islands. In fact 650 islands have been counted with an area bigger than 100 m2. The lake’s large size means it is home to an abundance of wildlife. You might encounter marine species such as ruddy turnstones, great cormorants, and white-tailed eagles drifting above the water. As well as picturesque views and varied wildlife, the sloping sandy beaches are also safe and pleasant places for family swimming. Lake Oulujärvi is also located inside Finland’s only lake hiking area, with managed walking trails and other related services.

The River Oulujoki Valley

The Oulujoki river is one of the largest rivers in Finland. Starting at Lake Oulujärvi, it continues through Muhos on a journey of more than 100 km to Oulu and the Gulf of Bothnia. The Oulujoki river has been an important trade and transport route for the people of the area for thousands of years. It was also the most well-known route in Finland and in Europe for transporting tar. Today the river produces large amounts of hydroelectric power even in national level and enough fish to meet the needs of recreational fishing. The river valley is also an important agricultural area thanks to its nutrient-rich soil and favourable micro-climate. Several tributaries join the Oulujoki river, the biggest of which being Kutujoki, Utosjoki, Muhosjoki and Sanginjoki.


A river valley running through beautiful countryside with plenty to see

The wide Oulujoki river runs through an idyllic rural landscape, edged with steep rock faces and lush foliage, with plenty of places to stop off when exploring off the beaten track. The river valley area offers several nature trails, camping centres, hotels and farm accommodation as well as businesses running nature activities of various kinds. The area also features historic and cultural sights, including art exhibitions, old wooden churches, historic farms and other historic buildings, some dating back to the seventeenth century. The river bank is an archeologically valuable area as a wealth of ancient monuments are found along it, some, such as depressions in the ground denoting settlement and pits to trap game dating to the Stone Age.

Lemmenpolku

About two kilometres long, Lemmenpolku, whose name means “lovers’ path”, runs along the northern bank of the Oulujoki river on top of the granite rock. The path showcases the natural and cultural history of the Oulujoki river from the ancient landmass to its use in transporting tar and the advent of hydroelectric power. One of the most amazing sights along the way is the conglomerate rock in Kieksi. It is the oldest part of the Muhos formation, petrified gravel only visible at this precise point. The exposed rock is a protected site. Walkers can start the Lemmenpolku trail either from Pyhäkoski power station or Montta Active Camping.

Erratic boulders

Glacial erratic boulders are rocks that sheared off the bedrock and were carried by the glacial ice. The best-known erratic boulders in Rokua Geopark are Isokivi (literally “the big stone” in Rokua, and the erratic boulder at Väätäjänniemi. Isokivi first drifted on the surface of glacial lake called Ancylus Lake with a block of ice and sank to the bottom of the sea when the ice block melted. The boulder consists of Precambrian schists and granites which were crystallized and metamorphosed in ancient orogeny processes as a high mountain range was tilted up in Finland. 

Isokivi is located beside the Emperor’s Road in the south-west corner of Rokua National Park on the border between Muhos and Vaala municipalities. It has served as a boundary stone for hundreds of years, marking the boundaries of municipalities, provinces and regions. The easiest way to find the stone is to take the Emperor’s Road in Neittävä and continue on the Emperor’s Road about two kilometres after the Pitkäjärvi car park in Rokua National Park.

Liimanninkoski nature trail

The Liimanninkoski nature trail takes you from the light-filled sloping meadows of the Muhosjoki river through dense spruce groves and lush broad-leaved woodland to Liimanninkoski rapids foaming at the bottom of the valley. Over thousands of years, the river has carved its way deeper and deeper into the sandy soil. In places the river has created a rocky river bed and beautiful granite stone steps, over which the rush of water bubbles and falls. Soft soils have caused the river’s drastic curves, or meanders, which make the river valley such a varied walk. The favourable conditions it provides make the river valley home to a wide variety of flourishing plant life and plenty of wildlife too. Liimanninkoski is a nationally protected area of broadleaf woodland. 

The Liimanninkoski nature trail starts at the car park by Suonkyläntie, which is signposted from the main road Valtatie 22. There is a shelter next to the nature trail right by the rapids, an ideal spot to stop for a breather, gaze at the foaming water and even make a campfire. The parking area nearby also has groups of tables undercover for a sit down and a picnic.
