7 Surprising Things You Didn’t Know About the Moravian Karst and Macocha Abyss

When aristocrats shaped the landscape

The minaret, the Karst… and your favorite pencil?

The Punkva cave that took 200 years to conquer

And the professor who blew his way to the bottom

When the underground river in Punkva cave disappears

Have you ever wondered what’s under the boat when you float through the Punkevní Caves? A glowing green current, sure. But under that? In truth, you’re floating on something that shouldn’t be navigable at all. Without the clever system of pumps, tunnels and water control, the river’s natural level would be six meters higher – flooding the passages and making the entire boat route impossible. So when you glide silently through the cave, you’re not just experiencing nature. You’re witnessing a quiet collaboration between cave and human ingenuity.

In 2025, during a scheduled maintenance shutdown, the pumps were stopped. The river receded – and suddenly, the boats hung in mid-air. The hidden was revealed. The rocky bottom appeared: smooth stone shaped by centuries of flow, gentle ripples etched in silence, traces of dynamite from a century ago. You could see exactly where nature stopped and human determination began. And yes – a few sunken smartphones showed up too, like tiny reminders of excitement and bad decisions. For a brief moment, light reached where it never usually goes. Not just from headlamps – but from curiosity. Then the pumps came back on. The water rose. And the cave returned to its usual silence – calm, flowing, secret.

A Walk Through Time: The Moravian Karst doesn’t forget. You just have to know where to look.

Step down into the shadows of the Macocha Abyss, and you’ll find a tiny, fragile flower clinging to the vertical rock face. It’s called Matthioli’s bellflower. Most alpine plants retreated to the mountains when the ice melted. But this one stayed. Tucked into the eternal shade of Macocha – a living relic of the Ice Age, rooted in silence and cool air. It remembers a time when snow covered this land for most of the year.

But walk just a few hundred meters uphill, and something magical happens.The shade turns to sunlight. The air warms. The landscape opens. And suddenly, you’re standing among Mediterranean plants – species you’d expect in Tuscany, Greece, or southern France. They’re here because, after the Ice Age, ancient grazers like bison and aurochs kept the land open, warm, and dry. And the plants adapted. They stayed.

Two climates. Two eras. One valley. You don’t need a time machine here. You just need to know where to look. That’s what I love about this place.
The Karst remembers. And it whispers its memories through leaves, rocks, and roots – if you’re quiet enough to listen.


The Moravian Karst remembers

The Moravian Karst remembers things we’ve forgotten.

The footsteps of knights.
The tools of early humans.
The flowers of ancient climates.
The boats that wait for water.

And sometimes, all it takes to hear the story… is to walk with someone who listens.
