At 581 m, the Grand Wintersberg (German: Großer Wintersberg) is the highest hill in the North Vosges in Alsace, France. The Grand Wintersberg lies about four kilometres northwest of Niederbronn-les-Bains. The massif separates the valleys of the Falkensteinerbach and the Schwarzbach. At its summit, which is made of Bunter Sandstone, stands a 25-metre-high observation tower, which offer hikers an outstanding panoramic view over the North Vosges, the Palatine Forest and the Upper Rhine Plain across to the Black Forest.
