When Luxembourg’s Little Switzerland Outsmarted Invading Armies

Written by Edoardo Laudani
To stroll through the Mullerthal—often called “Little Switzerland”—is to walk through a living fairytale. With its moss-covered gorges, labyrinthine rock formations, and secret waterfalls, the region feels like something out of a Brothers Grimm sketchbook.
But what most visitors don’t know is that this enchanted forest once played host to a very real, and very clever, kind of resistance. Not one of swords and armies—but of stones, caves, and misdirection.
Where the Forest Outsmarts the Strong
The Mullerthal’s story isn’t just about beauty—it’s about brains. In the 17th century, during one of the many regional conflicts that swept across Europe, this patch of wild Luxembourgish terrain became the perfect natural defense against invading troops.
While soldiers and mercenaries stormed grand castles and seized towns, locals vanished into the forest. Not because they fled—but because they knew the Mullerthal’s biggest secret: it confuses everyone.
Caves led to caves. Cracks disguised trails. Entire families lived for weeks inside rock shelters that blended so seamlessly into the environment that enemy scouts walked past them without noticing.
Legend says one battalion gave up chasing a group of farmers, convinced they had been swallowed by the earth itself.
The Curious Geography of Disappearance
How is that even possible? Because the Mullerthal isn’t a typical forest. It’s a twisted web of sandstone cliffs, narrow crevices, and shaded grottos, shaped by millennia of water and wind erosion.
Even with today’s GPS, it’s easy to lose your bearings—and back then, that was the point. The forest was more than refuge; it was a weapon.
Things You Shouldn’t Miss (or Might Miss Without a Map)
• Schiessentümpel Waterfall: The poster child of the Mullerthal, with a triple cascade and fairytale bridge. Arrive early before the selfie crowds.
• Wolfsschlucht (“Wolf’s Gorge”): A narrow, eerie rock corridor where legends say wolves—and sometimes resistance fighters—once hid.
• Hohllay Cave: A man-made cave used to extract millstones in medieval times. Local folklore claims it was also used as a hiding spot and meeting place for smugglers.
• Eppeldorf and the Hidden Springs: A lesser-known route for those wanting solitude—and a glimpse of untouched nature.
• Berdorf Labyrinth: A maze of tight passages that feels like Mother Nature’s escape room. No one leaves without bumping their head at least once.
More Than Just Pretty Paths
Mullerthal isn't just Luxembourg’s hiking crown jewel—it's a place where geology becomes history, and where the natural world once gave the weak a cunning edge against the powerful.
It’s also full of modern surprises: tiny farms selling local cheese, forest cafés with homemade schnapps, and trailside signs with stories that don’t just inform, but intrigue.
So why go?
Because some landscapes are more than scenic. They're strategic. They’re storytellers. And in the case of the Mullerthal, they’re tricksters too.
So tie your boots tight, follow the mossy walls, and remember: if you think you're lost, maybe the forest just doesn’t want you found yet.
