Pursiala pothole is a 8-metre deep natural feature, specifically a giant’s kettle (Hiidenkirnu in Finnish) formed by glacial meltwater. Discovered in 1965, the site was only just spared from development, as the outcrop was being blasted for construction use. It is nowadays protected and one of the Saimaa Geopark sites. Otherwise a great sight, the setting adjacent to industrial area is not the nicest possible. There is a small parking lot close to the pothole. Alternatively, a hike here can be combined with other nearby sights like Kaihu Esker and Mikkelinpuisto park.

The walking trail is short and easy, approximately 800 m, suitable for walking or MTB/Gravel. You can’t walk very far into the cave, but the cave and its surroundings are very impressive. The forest around the cave is a designated Heritage Forest. A headlamp or flashlight is recommended for better visibility inside the cave. Use caution if you plan to climb on top of the cave, as there are no safety rails on the cliffs.
