The sixth stage of the Ries Panorama Trail leads to the Riegelberg with heath vegetation and archeologically and geologically interesting Ofnet Caves. At the nearby Villa Rustica – a former Roman agricultural estate – you reach the stream valley Maienbachtal and shortly afterward the former Suevite quarry Altenbürg, where you can examine the melt rock typical of the Ries. After a longer hike, you reach the ruins of Niederhaus, one of the former Staufer castles, which crowns a craggy ridge above the Kartäuser valley. A detour to the ruins of Hochhaus is also possible, before you pass the Karlshof. An invitation to rest is offered by the idyllic fountain with spring and spring ponds. Shortly before Mönchsdeggingen, you reach the Geotope Kühstein, where rock exposures make Ries geology of the crater rim visible. Through the Kunstwald (woods with art installation), continue to the Buchberg, which offers a wide view over the Ries to the Hesselberg. The stage ends at the Mönchsdeggingen monastery.
Utzmemmingen – A community that is part of Riesbürg:
Shortly after it was state-approved as a leisure destination in 1972, this community became part of the newly formed municipality of Riesbürg in the Württemberg part of the Ries in 1973. The name is a combination of “Ries”—which itself is derived from the Roman province name “Raetia”—and “Bürg”—referring to the former existence of several castles nearly, including the Alten Bürg.
