 The Erlenbach has a main source and a rather smaller subsidiary source, which are only a few hundred metres from one another on the eastern flank of the 445-metre-high Löffelsberg.They are located in the Wasgau, which comprises the southern part of the Palatinate Forest and the adjoining northern part of the French Vosges Mountains.Initially the stream flows eastwards passing through the parish of Oberschlettenbach, its two headstreams meeting after 2 km, the smaller brook emptying from the right into the bigger one.
