Discover the geological marvels of Sukulanrakka, nestled just 25 km from Rovaniemi. Explore the 14 fascinating ‘devil’s churns’—unique potholes carved by nature itself. Among these, three of Finland's largest potholes.

Admire the largest pothole, which is 8 metres in diameter and 15 metres deep. See two others that measure depths of 9 and 10 metres, perched majestically atop the rocky slopes.

Learn how these incredible formations were sculpted around 10,000 years ago as the continental ice sheet melted, unleashing powerful torrents of meltwater that shaped the landscape. As rushing waters surged through tunnels at the base of the glacier, they eroded the rock, clearing away soil and leaving behind striking depressions.

See how the swirling eddies and boulders created by these powerful flows drilled into the rock, resulting in the captivating devil's churns seen today.
