Juuma, Myllykoski and Jyrävä in Oulanka

From the Juuma car park go through the wooden gate and follow the green markers down steep steps to the Niskakoski suspension bridge. Cross it and walk on to the old mill at Myllykoski, where the loop begins. Go anticlockwise, as Metsähallitus suggests: stay on this bank and follow the long Aallokkokoski rapids to the Jyrävä waterfall. Carry on along the river to Harrisuvanto and cross the longest of the suspension bridges. Climb about 300 steps to the Kallioportti lookout, then follow paths and duckboards past Pyöreälampi pond to the Myllykoski suspension bridge. Cross it and walk back to Juuma the way you came.

It is 11.8 km round with 214 m of ascent; allow about 3½ hours. The grade is Moderate: clear paths and duckboards, but long, steep wooden stairs down to the river and up again.

The stairs are slippery when wet, and in winter, when the loop usually stays open, packed snow makes them worse: take ice grips. The Myllykoski bridge takes at most 10 people at a time. After Harrisuvanto keep to the path: the Juuman vuomat area beside it is closed to visitors from April to December. The toilets at the start open only from June to September.

Metsähallitus lists no parking fee. Seasonal buses from Kuusamo, Ruka and Salla stop about 150 m from the car park; otherwise take a taxi.
