Due to its small-scale relief, the uplands of the Wasgau are characterized by considerable diversity of forms with rather isolated individual peaks - particularly the conical hills or Kegelberge - which reach an average height of 400-500 metres above sea level. The highest peaks are in the northern and central Wasgau (such as the Wegelnburg, 572 m, and the Mohnenberg, 547 m), especially near the edge of the Rhine trough (e.g. the Grand Winterberg, 581 m, and the Rehberg, 577 m), while the bunter sandstone block in the west and south descends from about 500 m (Wasenkoepfel, 526 m and Großer Eyberg, 513 m) to an average of about 350-400 m at the Saverne. Also typical is the number of variably shaped rock formations, mainly rocks of the Lower Triassic sandstone, the Trifels and Rehberg beds, that are found on many hills in the Wasgau (see the sections on Geology and rock formations). In his typology of mountain and rock formations of the Wasgau, Geiger distinguishes the following six forms: hill blocks with rock outcrops, table hills; rock slabs; ridges with rock faces, hill cones with rock blocks; hill cones with rock towers and domed hills. In addition there is a host of hilltop observation towers (e.g. on the Grand Wintersberg, Rehberg, Stäffelsberg and Wasenkoepfel) that offer visitors a 360° panorama.
