Lukas has a unique motivation to climb the 7 Summits of the Alps. Reaching the summit is only one part of the goal - setting up and walking across a slackline close to the mountaintop. The journey starts on top of Germany at the Zugspitze and leads Lukas and his team from France to Slovenia. The highest peaks of the alpine countries hold great potential for spectacular highline but quickly turn out to be a real challenge for Lukas’s developing skills as an alpinist.
