The Devil's Nest, Natural sinkhole and cave formation in Kurikka, Finland
The Devil's Nest is a natural sinkhole in Kurikka featuring a wide opening that descends steeply into the ground. The cavity reveals eroded rock layers along its sides and demonstrates how water carved through stone over extended periods.
The sinkhole formed over roughly one million years as water slowly dissolved and eroded the surrounding rock. During ice ages, glaciers and meltwater accelerated this process, deepening and widening the cavity significantly.
Local legends named this sinkhole after the Devil, reflecting old beliefs about the deep cavity. The place held sacred meaning for ancient Sami communities who gathered here for rituals.
The sinkhole is open from May through August with daily access, then limited to weekends in September. A viewing tower beside the cavity provides safe views down into the formation without needing to descend.
A 21-meter tall observation tower allows visitors to view the cavity and surrounding Finnish landscape from above. This vantage point offers a rare perspective on the complete structure of the sinkhole from an elevated position.
