The road to the viewpoint starts from the town of Aurlandsvangen. It has very nice promenade, you can walk there. There is also a supermarket in the center (N 60 54.344 E 7 11.216).
Previously, all travelers after reaching the lookout continued on their way further north, along the "The snow road". Now there is no need for this, since the Lerdal tunnel was built under the mountain.
Getting there: parking N 60 54.501 E 7 12.777. There are tourist minibuses from Flåm for 34 euros (2019), information is here.
