The low mountain range runs from north to south and reaches its highest point at the summit of the Heuberg (often also called Rosalia) near Neudörfl, before descending again towards the village of Weppersdorf.

The boundary continues over the basin of the Hochwolkersdorf hamlet of Alm, along the so-called Totengraben in the Essengraben and then via the Graben into the valley of the Schwarzenbach.

The highest point is the Heuberg with its Rosalia Chapel, which reaches a height of 748 metres.

The Rosalia Mountains can only be crossed by the road from Mattersburg in Burgenland to Hochwolkersdorf in Lower Austria.

In its lateral valleys, favourable conditions have led to extensive orchards and vineyards.
