The Buschberg, the Mecca for racing cyclists in the Weinviertel? Certainly one of the most beautiful landscapes in this region and one of the few opportunities in the Weinviertel to ride longer climbs or descents. Otherwise you have to deal with many and sometimes quite steep but rather short climbs and descents in the hill country. In addition, the "mountain arrival" is a worthwhile goal. In fact, the Buschberg summit is the highest elevation in the Weinviertel, the roof of the region, so to speak (491 m). There are essentially three climbs/descents for road bikes (much more for mountain bikes). The most difficult option is probably that of Niederleis - the most strenuous on the ascent, as it is steepest and longest, and the most dangerous on the descent, as it has the most bends. The climbs from Pyhra or Gnadendorf and from Michelstetten or Schletz, on the other hand, are a little more leisurely (the last section is the same for the climbs from Michelstetten and Niederleis). The climb from Pyhra or Gnadendorf is perhaps the easiest as it almost never gets above 10%. The section through the forest from and to Michelstetten/Schletz is very nice (there are also flatter sections here) - but be careful on the descent: at the end there is an approximately 8-10% gradient (in the ascent this is the case with this variant one of the steeper sections) a confusing T-junction with a stop sign (to the left it goes to Michelstetten, to the right to Schletz) - in June and July the view here is often additionally limited by tall crops. If you have a decent tooth here, you risk a nasty accident.
You can drive over the ridge from all sides (past the car parking lot). From the parking lot, an asphalted section leads towards the summit. However, reference should be made to the general driving ban. This piece would be a bit of a challenge again, as it has a gradient of more than 10% in places - especially in the last section (not a big deal compared to passes in mountainous areas, of course). Here, too, caution would be required on the descent due to the many sharp bends, and pay particular attention to hikers and other cyclists. The summit itself is not accessible, not even for hikers, since the radar station, the "radar ball", for civil air traffic, which can be seen from afar, is located there. Below it you can stop at the lowest Alpine Club hut (Buschberghütte).
