An incredible adventure

23rd May 1863. In the ancient Icelandic book of his student Alexander von Humboldt the Hamburg geology professor Otto Steinbrock discovers a yellowed parchment with mysterious characters and apparently unbelievable content:

“Descend into the crater of Sneffels Jökull and you will reach the center of the earth ...”

Unbelievable! And yet he lets Alexander convince him to approach this dangerous adventure together.

You can experience what awaits them on their trip! Descend into the dripstone caves of Rübeland, because our "Journey to the Center of the Earth" begins right here: deep underground, in the heart of the Harz Caves.

Come with us and help make the seemingly impossible possible!
