Launch Site Details: Launch Window: North-facing Difficulty: Difficult Elevation: 1640 meters Cable Car: Yes Coordinates: 9.32863906, 47.29111133 Hike Time: 2 minutes For experienced pilots, the steep north-facing launch site is an option in good north wind conditions. However, it is not suitable for beginners due to the minimal runway. Mastery of wing control is essential here. The official launch site is the west-facing one. All take-offs are very close to the gondola station.
