The Astenturm is one of the most popular excursion destinations around Winterberg in Hochsauerland. Its location on the hilltop of the Kahler Asten is characterized by the landscape of the Hochheide, a protected landscape with diverse flora and fauna. The Museum für Naturkunde Münster has a branch within the tower walls for anyone who would like to find out more. The "interactive table" provides an entertaining and impressive source of information. This modern medium informs visitors about the hiking area, the heath nature trail and winter sports around the Astenturm.
