Trasshöhlenweg

13,000 years ago, the Lacher See volcano erupted, so this rock was created. At that time, the Romans cut off large blocks of trass and shipped them across the Rhine to Italy. In the 1800s, trass was mined and processed into a kind of cement in the mills. Today you can see these caves.

The Trasshöhlen are really worth seeing and freely accessible. The adjacent gorge is very beautiful with many attractions.

Nice path through different caves / passageways. The Trass caves are a great experience for young and old.

The caves are quite suitable for people with claustrophobia.

"The sky in the Brohltal darkened when the Laacher Lake volcano erupted only five kilometers away, and a glowing mixture of lava particles and gases spewed into the atmosphere at intervals, each time the eruptive pillar collapsed, the material raged Ashes and lava particles filled the valleys up to 60 meters high, and the once loose materials of the glut avalanche have, over time, become a rock known as "trass" in our region, which was already built by the Romans In the Brohltal Trass, they used it, among other things, to build a house, adding finely ground lime and water to a mortar that hardens even under water, and it seems likely that it was Dutch people who exploited it in the Brohltal valley since the 16th century Trass is ideal for building dikes and docks, and it was they who gave the name to the volcanic cement: "Tyrass" is Dutch It's called "glue." The walls you see from here are hollowed out and can be visited. Because of their poorer quality, they were no longer interesting for the mining and are today an impressive testimony of the huge glut avalanche that once filled the whole valley. "

Nice cave especially for children.

The path passes through this impressive cave

Super nice cave system !!! CRAZY !!!

It's worth looking around the corner from time to time. While exploring you will discover other entrances and caves.

Be sure to follow the path after the first large cave. Once you've walked under the rails, there are many more caves to come!

Very interesting caves that are free to explore.

Well worth it, impressive nature with boards well explained.

Beautiful old Bergwekshöhlen. The trail leads partly through.

Old pump house ..... very exciting for children to enter the house and examine the water basin in the rear part of the house. Take a flashlight with you ...

Great highlight, very interesting.
Much is explained on the boards.
I can really recommend it.

Fantastically beautiful but don't underestimate the stairs.
You have to be good on foot and sure-footed.

A good 30m is in the rocks. Really cool. But watch your head 😉

Pleasant little quiet hike

Unfortunately, the cave is very hidden.

Really interesting! However, flashlight is a must.

Freely accessible and path running through the cave

The name dream path is well deserved

Very impressive to walk through the caves like that. Is something for children.

Great hike through varied landscape, we are extra from the Lahn-Dill-circle arrived for the tour were thrilled!
