For an awesome view of the region, make the journey up to Aussichtsturm Unnenberg. You may be able to spot some landmarks in the distance.
This scenic viewpoint is on the to-do lists of many travelers to Marienheide. But Aussichtsturm Unnenberg isn't the only highlight in the area. Aggertalsperre, Gumbala Water Park, and Lieberhausen Church are some other worthwhile attractions nearby.
