Aschestrom in Bad Tönisstein
Almost 13,000 years ago, glowing clouds from the Laacher See volcano raced down the Brohltal and filled it with loose volcanic masses.
This impressive spectacle can still be seen here today. Follow the road on the right behind the building complex and go uphill for a few meters. On the slope to the right, the layers of ash (trass) that have settled on the rocks of the older basement can be clearly seen. And where volcanoes were active, mineral springs are usually not far away.
At the nearby baroque fountain temple of the Bad Tönissteiner mineral springs you can refresh yourself with water from the depths.
