Every winter, the streams trickling down Korouoma's cliff faces freeze into enormous pillars and curtains of ice, transforming a remote canyon in Finnish Lapland into the country's premier ice climbing destination. But the frozen waterfalls are only the most dramatic feature of a landscape that has been shaped over millennia. Korouoma is a fracture valley roughly 30 kilometers long, a few hundred meters wide, and up to 130 meters deep, carved into the terrain near the municipality of Posio. At its floor, the Korojoki River meanders northwest toward the Kemijoki, lined by flood meadows and herb-rich forests that feel wildly out of place this far above the Arctic Circle.

The northern reaches of the valley sit on calcareous soil, producing vegetation noticeably lusher than the southern stretches. Along the Korojoki's banks, flood meadows and herb-rich forests thrive in the moisture-rich microclimate ...

A marked hiking trail follows the canyon floor, passing through some of the most striking scenery in Finnish Lapland. In winter, the tra...
