The Booser Doppelmaar (Double Maar of Boos) comprises two maars that have silted up and, today, form shallow depressions in the countryside. They lie on the territory of the village of Boos (in the collective municipality of Vordereifel), a few hundred metres west of the village itself. The two maars were formed 10,150 to 14,160 years ago and belong to the Quaternary volcano field of the Volcanic Eifel. From a natural region perspective it lies in the south of the Hohe Acht Upland (which belongs to the natural regional major unit of the Eastern High Eifel), ca. 7.8 km south (more precisely half west-by-south or 185.625º) of the summit of the Hohe Acht.
