Speleology
Venture underground and awaken your senses: the scent of damp earth, the chill of ancient stone, the sound of your breath in the stillness.
In Le Marche, the caves don’t just hold secrets. They share them - if you listen carefully.
Le Marche isn’t only made for mountaintops and coastlines -it’s a land carved from within. Its limestone heart hides a secret world of vast caverns, narrow passageways, and ancient rivers flowing in darkness. Here, speleology becomes more than sport; it’s an invitation to move slowly, breathe deeply, and witness time in stillness.
From beginners to seasoned explorers, the region’s caves offer rare opportunities to engage with geology, history, and the humbling power of nature - underground.
How to
Explore the wild silence of Le Marche
First of All: Ask an Expert
If you’re new to caving or planning to explore a complex cave system, your first step should always be to consult an official guide or a local speleological group. Not only will they ensure your safety, but they’ll also enrich your experience with stories, science, and insights that you’d likely miss on your own.
Many of the most famous cave systems offer guided tours designed for all levels, from curious beginners to seasoned explorers. These visits are a safe and fascinating way to discover the underground world—no special skills required, just a sense of wonder.
Trust the experts, and let them lead you into the heart of the Earth - safely, responsibly, and with eyes wide open.
Gear Up, Stay Safe, and Show Respect
Before entering any cave, be sure you're properly equipped and mentally prepared. Dress for the environment with waterproof, abrasion-resistant clothing, a warm layer for cooler temperatures, sturdy hiking boots with strong grip, gloves for protection, and a helmet with a reliable headlamp.
If your adventure involves vertical sections, prioritize safety. Use the right climbing gear—harnesses, ropes, carabiners, and descenders—and always double-check your setup before moving.
And above all, respect the cave. These fragile, ancient environments have taken millions of years to form. Leave no trace, avoid touching delicate formations, and take nothing but memories and photos.
Where to go
Frasassi Caves: a UNESCO World Heritage underground wonder
It all began with the sound of a stone falling into the darkness—and the long, breathless wait for it to hit bottom. That moment marked the discovery of the Grotta del Fiume, the first chamber of what would soon be revealed as one of the largest and most spectacular underground karst systems in Europe: the Frasassi Caves.
Located in the municipality of Genga, within the Gola della Rossa e di Frasassi Regional Natural Park, this vast subterranean network stretches for over 13 kilometers, forming a surreal world of natural cathedrals, silent lakes, and extraordinary rock formations. Widely considered one of Italy’s most fascinating natural wonders, the Frasassi Caves are among the most significant cave systems on the continent.
Carved over 190 million years by the slow, persistent action of water on limestone, these caves are adorned with breathtaking natural sculptures. The Sentino River, seeping through the rock and fault lines, gradually dissolved calcium carbonate. Over millennia, as mineral-rich droplets fell, they created impressive stalactites—hanging from the ceilings—and stalagmites—rising from the ground. Some formations are towering and majestic; others are oddly whimsical, shaped by chance and time.
Inside the caves, the environment remains remarkably stable, with a constant temperature of 14°C (57°F) and 98% humidity year-round.
This consistency has preserved the delicate ecosystem and created the ideal conditions for an unforgettable underground journey - whether you're drawn by science, adventure, or sheer natural beauty.

Monte Nerone: a speleological paradise
Monte Nerone, with its dramatic limestone terrain, is a treasure trove of natural caves—steeped in mystery, prehistoric echoes, and raw geological beauty. Its rugged slopes, sheer cliffs, karst formations, and deep gorges have earned it international acclaim among speleologists and hikers alike.
Among its many wonders is the Anello delle 4 Grotte—the “Ring of the Four Caves”—a unique trekking route that links four extraordinary natural caverns: Grotta degli Orsi, Grotta del Falco, Grotta del Borghetto, and Grotta dei Clasti. This circular hike offers a journey through time and stone, unveiling untamed subterranean landscapes, captivating rock formations, and the silent story of Earth’s ancient forces. It’s an unforgettable adventure for nature lovers, cave explorers, and anyone drawn to the hidden world beneath the mountains.
