In the Reisseck Group there are numerous mountain lakes, of which the Radlsee (Hoher See), the Hochalmsee (Spapniksee), the Zwenberger See and Mühldorfer See are the most important. The water is used by the Reißeck-Kreuzeck Hydropower Group to supply the hydroelectric power plants in the Reißeck municipality. For tourists the mountains are accessible from the Möll valley on the Reisseck Funicular. However, service on the former Reisseck Mountain Railway connection to the mountain lakes plateau discontinued in 2014. The former ski area has been closed.
