The Gemündener Maar is the northernmost of the three Daun Maars. It lies in the immediate vicinity of the village of Gemünden and ca. 1.5 km south of Daun in the Eifel and in the German state of Rhineland-Palatinate.
The maar lake is around 325 meters long, 300 meters wide and up to 38 meters deep. It has an area of about 7.2 hectares. The maar is 30,000 years old which makes it younger than the Schalkenmehrener Maar and is the smallest of the three maars of Daun. Its water surface lies at an elevation of ca. 406 m above sea level, the floor of the maar at 368 metres above sea level. Parts of the lake are used for bathing in summer, which has a marked effect on the surrounding nature reserve.
