Description
The paragliding site at Sonnwendstein, located in the Mariaschutz region of Austria, offers a unique flying experience. The takeoff altitude ranges from 1474 to 1499 meters and is considered easy. However, it is not frequently used, making it a serene spot for soaring flights. Due to its isolated location, it is not ideal for cross-country (XC) flights.
The southwest (SW) launch site is situated below a transmitter. Launches are possible with winds coming from the south-west, but caution is needed as strong west winds can cause turbulence due to a nearby forest. Additionally, south-west winds in Central Europe can be associated with Föhn (south-southwest) and stormy conditions (west).
The SW launch site is straightforward, with a flat area that can accommodate two gliders. The slope gradually descends, providing ample time for a safety check and the option to abort the launch if necessary. However, if a launch is aborted, the slope outside the designated launch area can be challenging, making it difficult to untangle lines.
After launching, pilots can attempt to catch thermals on the steep southwest slope from midday or head to the landing zone on the north side. The Sonnwendstein is the last flying mountain of the Vienna Basin towards the west. Its isolated position often spares it from dense fog during winter, making it a hidden gem. In spring, the mountain can be thermally active, with climb rates exceeding 5 m/s, though it is not as reliable as Hohe Wand or as intense as Rax. Summer thermals are usually only present after a cold front passes.
For beginners and infrequent flyers, Sonnwendstein is only moderately suitable outside the winter months. The mountain blends seamlessly into its surroundings and is visited by few pilots. Less experienced pilots might prefer Hohe Wand, while more advanced pilots might opt for the more challenging Rax.
Despite its understated appearance, Sonnwendstein offers beautiful flights for the average pilot. The steep, mostly forested slopes receive good sunlight during the thermally active season, providing early thermal opportunities from late morning. The prevailing valley wind on the north side allows for soaring.
In spring, flights with over 1000 meters of altitude gain are possible, making Sonnwendstein suitable for cross-country flights, with the entire Mürztal valley to the east. In winter, when the surrounding area is shrouded in fog, Sonnwendstein often remains clear, providing uninterrupted flying weather. The landing zone, elevated above the foggy basin, remains accessible, allowing for enjoyable winter flights.
Even in winter, the SW launch site can offer weak thermals or soaring opportunities until mid-December. However, the mountain's demands on pilots should not be underestimated. Most launch sites are simple, and the thermal conditions are manageable for the average pilot. The landing zone, however, can be tricky due to stronger valley winds and its inclined nature. Mastery of planned landing approaches and flexibility is advantageous.
During west and southwest conditions, cold air outflows from the Mürztal valley can occur, indicated by strong ground winds on the nearby highway. This does not always mean a storm at the landing zone 500 meters away, but such surprises should be anticipated. Wind conditions can be assessed from the air by observing the flags at the highway rest station in the valley.
For walk and fly, there are two options: from the former lift station via the Gebirgsjägersteig (approximately 2 hours without gear, longer with gear), which winds up the north side and crosses the old lift route, or taking the lift to Hirschenkogel and then following the ridge path (about 1 hour with gear). For larger groups, a shuttle can be arranged with the owner of Polleres Hütte.
