Geo-excursions for families in the Volcanic Eifel region
 Did you know that gases from underground magma still bubble to the surface of Lake Laach, turning the water into a fizzy, sparkling lemonade in some places? Or that there are caves in the Eifel region that you can explore on your own with your children and a flashlight? All the hikes have been tested and approved by children. And if you forget your wallet? No problem – all the tours described are free of charge. 128 pages, numerous photos and illustrations, 13 x 21 cm format, 2020.
