The Pisamalahti hill fort is located in a rocky area bordered by perpendicular bedrock fault zones. The hill fort is surrounded on three sides by steep slopes and rises around 55m above Lake Saimaa. In places, it’s almost treeless and eye-catching scarps rise vertically from the water and can be seen far across the lake. The hill fort is one of Finland’s most famous Iron-Age hill forts, and since it is well protected by nature it has only required reinforcement on its eastern edge, where there remain several dozens of metres of rocky embankments around 3m wide and over 2m high in places. A marked path leads to the site from a car park around 400m away, and it is also possible to reach the site by boat. The terrain in front of the quay features boulders of various sizes and boulder caves.
