Gelpetal

The Gelpetal forms together with the Saalbachtal a wooded recreational area in the south of the city Wuppertal on the border to Remscheid.
The two streams Gelpe and Saalbach unite in the lower Gelpetal mentioned in Zillertal and lead a short time later in the Morsbach, one of the larger tributaries of the Wupper.
