Formed from lava and fire
Nine volcanoes make up the south-eastern area of the recent volcanic field in the western Eifel. Bad Bertrich is home to a hot spring, which was already in use in Roman times, and is famous far and wide for its health-giving properties. The formation of the valley, the genesis of the volcanoes and the origin of the hot spring represent a unique combination of natural events, which have attracted the attention of many geoscientists over the years.

The parish church and a number of houses in Kennfus are particularly interesting, having been built from blocks of dark lava and abundant light-coloured tuff.
The 10-km hiking trail Geo-Route Bad Bertrich leads walkers back along the ancient lava flow, offering information on the local geology along the way.
