In Helvetinjärvi National Park, the trail section between Haukanhieta and Helvetinkolu floods regularly
08/25/2025The trail section between Haukanhieta and Helvetinkolu in Helvetinjärvi National Park is flooded for most of the year at the Sammakkolampi area, near Helvetinkolu. The flooding is caused by a beaver dam. After long dry periods, the area may be dry. We are unable to monitor the flood situation weekly. Usually, the section can be crossed with rubber boots, but the water level varies between 10 and 40 cm.
