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 meters in diameter and 15 meters deep. See two others that measure depths of 9 and 10 meters, 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.

Thansk you again so much for this visit. It is something we could have done by ourselves but we would not have gone as deep in the forest, might not have seen as beautiful landscapes and nature's arts. All of the exeplanations arround were really great too. He was excited and got us excited too for this tour. Nice thing too, churns are right at the parking lot so it is a really easy place to go.
