The Mariahilf ("St. Mary's help") loop is full of  exceptional landscape variety. It starts at the pilgrimage chapel of Lengenbach, where a large parking lot is at your disposal directly behind the charming chapel.

For the first kilometers of the Mariahilf loop you walk on a slowly ascending crushed stone path through the idyllic Lengenbach valley, with pine woods on one side and diversified meadows on the other. Nature lovers have always known the Lengenbach valley as a species-rich kingdom for butterflies. After about an hour, you reach the village Höhenberg above St. Helena. A footpath behind the conference hotel Schönblick leads towards Sturmwiese. At the edge of the wood a trail branches off half-left. It first runs along the slope and later reaches an opening with a gorgeous vegetation of shrubs.

Further on through the wood you will soon reach the grotto underneath the Mariahilf church. At the church level there are wonderful views into the surrounding landscape. A narrow path leads to the village of Lähr. In an eastern direction the Mariahilf loop now leads to the forest at Sandberg on crushed stone roads. There you soon reach a marked "spider's web" junction in the Heiligenholz. After about half an hour on a beautiful forest trail you come to another junction in the woods. You walk further on in an eastern direction through the quiet forest of the Heiligenholz. Later on, you pass a large forest meadow, and at last you descend down into the small village of Arzthofen in the valley of the Weisse Laber. Here you meet the main route of the Jurasteig which, at first, takes the hiker up to the Schellenberg across a sandy pine and blueberry forest and finally down again to the Lengenbach chapel.
