Initially heading in a southeasterly direction, but subsequently turning eastwards, the Modenbach flows through the valley named after it towards the gently rolling vineyard country by the German Wine Route.

Below Hainfeld it turns northeast and, passing Edesheim, the stream leaves the hill country and flows through the western part of the Upper Rhine Plain.

Sights in the area of the upper Modenback include the ruins of Meistersel Castle on the right bank, and the mill of Buschmühle near the village of Weyher.

The classicist main building of the Buschmühle, converted in 1838 into the style of a manor house, has been used as a restaurant since 1900 and is also used as a training centre for gastronomy today.

The edge of the mountain range north of Hainfeld offers viewing points from a height of 600 metres above sea level over the Rhine Plain below.
