Krieriegel Trail

Part of the Rosalia MTB Trail: from north to south with a steep climb and a gentle descent, from south to north the trail is reversed. Shared trail – please be careful of hikers and other users.

The Krieriegel is a 682 m high mountain in the Rosalien Mountains in Burgenland. It is located in the municipality of Wiesen, southeast of the Lanzenkirchen cadastral municipality of Ofenbach and northwest of Forchtenstein. [wikipedia]
Towards the Rosalien Chapel, a steep and narrow climb that is not entirely easy. The shared trail occasionally leads to traffic jams with hikers :-)

Coming from the south, it's also quite rideable on a CX or gravel bike, even if it's a bit bumpy. From the other direction it's probably too steep to get by without pushing.
