Park the car at Fionay Lakes' car parks (S).
Follow the trail between the two lakes passing under the cable car service (1). Let the two crossing paths head off to the right, especially the one leading to Alpenpässe-Weg (2).
From this crossing, the trail become very windy, the slope isn't too high and allows you to easily access the cable car destination station to the right.
Keep heading upwards through the last stretch of twists and turns and reach the ledge before Louvie Hut and Lake, today's stopover (3).
