The wild rivers of Oulanka in packraft

Transfer to the village of Käylä and first launch in the middle of nature. The morning is devoted to an introductory whitewater course: river reading, basic manoeuvres and safety.

After a few practice runs on a class I rapid, the first lake is lined with pine and silver birch trees. We then begin the descent of the Kitkajoki, with its clear water and green reflections. We set up our first bivouac near a laavu (Finnish shelter) on the riverbank. There's still time to practise manoeuvring on the gentle currents before dinner under the stars.

Right from the start, a class II rapid gets you going (portage possible). The river then widens into a series of calm lakes, perfect for watching waterfowl. Cross the Niskakoski (class II) and then cross Lake Jyrävänjärvi.

A portage of Myllykoski (class III) is compulsory, except for the most experienced. This emblematic site is home to an old restored wooden mill, a vestige of the days when water power was used to grind cereals. We'll take the opportunity to stop for lunch and explore the surrounding area, where footbridges and pontoons offer great views of the rapids.

In the afternoon, we walk around 1.5 km along the Karhunkierros trail, a legendary hiking route in Finland. The route takes us past the Aallokkokoski (class IV), a powerful rapid with high waves, and on to the spectacular Jyrävä waterfall (class V), some fifteen metres high, which flows into a pool surrounded by pine trees. We set up camp next to a traditional hut.

Navigation on a calm stretch, through forests of hundred-year-old pines, to the confluence with the Oulankajoki. Depending on the conditions (current, wind), you can combine paddling and walking to reach the evening shelter.

A short secret trail back to the Karhunkierros, one of Finland's most famous treks. Stop at Ansakämppä for lunch overlooking the river, then continue to a class V rapid where the camp is set up just downstream.

Navigation resumes, this time on a stretch without rapids but with a steady current. The river winds through a narrow canyon, with sheer cliffs and forests as far as the eye can see. Bivouac by a rustic shelter.

Final paddle to Huotinniemi. One-hour transfer to Kuusamo and return to base camp. Afternoon free to visit the town or relax before a final dinner.

Optional transfer to Kuusamo airport at 9am.
