Komorní hůrka

Komorní hůrka is a forested hill rising to 504 metres above sea level on the cadastral boundary between Cheb and Františkovy Lázně in western Bohemia. It is one of the youngest volcanoes on Czech territory — a cinder cone built from volcanic material, active roughly 850,000 years ago, though some researchers argue its final eruptions may have occurred as recently as 350,000 years ago. The site is now protected as a national nature reserve covering 7.1 hectares and forms part of the Egeria Geopark, a cross-border network spanning the Czech-Bavarian borderland.

Why did Goethe take an interest in this hill?

The story of Komorní hůrka is tied to one of the most famous scientific controversies of its time. German poet and naturalist Johann Wolfgang Goethe visited the hill repeatedly, taking part in the dispute over its origin — proponents of a volcanic explanation clashed with so-called Neptunists, who rejected the idea that the rock had a magmatic source. Goethe proposed drilling through the hill to settle the question empirically, but it was Count Kašpar Šternberk who eventually carried the project out. Work on the exploratory adit ran from 1834 to 1837 and was completed only after Goethe's death. The tunnel confirmed the hill's volcanic origin, contributing to the development of Czech geology as a field.

What can visitors see there today?

The area has been under continuous protection since 1933, making Komorní hůrka one of the longer-standing protected natural sites in the region. An educational trail, roughly one kilometre long and marked with three information panels covering geology, botany and history, once circled the hill, starting at the edge of a small forest in the village of Komorní Dvůr, along the secondary road connecting Cheb and Františkovy Lázně. The Šternberk adit itself remains closed to the public on a day-to-day basis, but for several years the municipal cultural centre in Františkovy Lázně has organised seasonal guided tours into the tunnel. These tours draw steady interest, typically welcoming groups of around fifteen visitors at a time, with total seasonal attendance reaching well over a thousand people.

Who is this attraction for?

Komorní hůrka appeals mainly to visitors interested in geology and the history of science, as well as travellers looking for a quiet, wooded hill close to the well-known spa town of Františkovy Lázně. Its proximity to Cheb also makes it easy to combine a walk up the hill with a visit to the city or a spa stay.

Frequently asked questions

Is Komorní hůrka an active volcano? No — it is an extinct volcano whose last activity took place hundreds of thousands of years ago. Today the site is protected as a nature reserve rather than posing any geological hazard.

Can visitors enter Šternberk's exploratory adit? The adit is normally closed to the public, but seasonal guided tours are organised that allow visitors inside with a guide.

How do you get to Komorní hůrka? The hill sits along the road connecting Cheb and Františkovy Lázně, near the village of Komorní Dvůr, making it an easily accessible destination from either town.

Is it worth combining with a stay in Františkovy Lázně? Yes — its closeness to this well-known spa town makes a short walk up the hill a natural addition to a spa stay or a broader visit to the Cheb region.
