Open Air

Open Air is a 55-metre (180 ft) sport climbing route on a limestone cliff face at the Schleierfall climbing area in the Wilder Kaiser mountains, in Tyrol, Austria. In 1996, German climber Alexander Huber made the first free ascent and after completing his redpoint, he proposed a technical grade of 9a (5.14d), which ranked it alongside the highest grades of any climbing routes at that time.
