No special access issues
Only 20 minutes drive from Helsinki!
Drive highway E18 and take exit 56, the one with Neste gas station. Turn right to Eriksnäsintie and follow that untill the road ends and you reach the sea. Drive slowly on the last bit of the road so not to scare horses nearby.
Path leading to the cliff starts from the parking place and follows the shoreline. Keep the sea on youre left and you cannot mis the wall.
[Update 06/2022] The parking is not free anymore, as the landowner has decided so.
