Lake Hoffeld, a former basalt quarry on the Burgkopf hill above Hoffeld, is not open to the public. It is used by the Hoffeld 1990 e.V. fishing club and is fenced off on all sides.

Former basalt quarry I've even been swimming there before. If you're nearby, it's definitely worth a visit.

The Boos Double Maar consists of two silted-up maars, which today appear as shallow depressions in the terrain. They are located within the municipality of Boos. The two maars formed between 10,150 and 14,160 years ago and belong to the Quaternary volcanic field of the Volcanic Eifel. The two maars form large, circular basins surrounded by tuff embankments. They lie on a west-southwest-east-northeast trend, thus following the Variscan strike of the subsurface. The west-southwest maar has a diameter of approximately 700 m and a depth of between 30 and 60 m; the east-northeast maar is between 650 and 700 m and a depth of between 50 and 87 m. Both depressions are very humid, so there are still areas that have a permanent water surface. The waters were formerly used as fish ponds, but later silted up and served as meadows and fields. Today, there is once again a fish pond in the west-southwestern part of the maar, the Booser Weiher. In the vicinity of the maars, there are tuff pits where the volcanic tuff formed during the eruption of the maars was mined. Very beautiful nature.

The history of the Volcanic Eifel can be explored at the Booser Doppelmaar. The Booser Doppelmaar consists of two silted-up maars, which today appear as flat hollows in the terrain. The two maars were formed between 10,150 and 14,160 years ago. Viewed from above, the two maars are circular basins. The west-southwest maar has a diameter of around 700 m and is between 30 and 60 m deep, the east-northeast maar is between 650 and 700 m large and has a depth of 50 to 87 m. The two hollows are very wet, so there are still places that have a permanent water surface. The water areas were previously used as fish ponds, but later silted up and served as meadows and fields. Today there is again a fish pond in the west-southwestern maar, the Booser Weiher, see also https://de.wikipedia.org/wiki/Booser_Doppelmaar

The Booser Doppelmaartour is an Eifel dream trail. It is important that you look in vain for water here, because the two maars are so-called dry maars.

From a wooden bridge there is a wonderful view of the swampy foothills of the rainwater-filled Booser Maar, which is located in the Hohe Acht mountain region and approx. 8 km south of the Hohe Acht. The maar lies in a circular tuff basin, whose tuff walls are covered with swampy meadows and the edge of the bank is overgrown with reeds. Galloways graze in the dry, higher meadows.
