Geocaching is my excuse to explore the unexpected. Case in point: Yverdon-les-Bains, a lakeside town that sparked a spontaneous journey—complete with an impromptu swim. With Creux du Van as our destination and the trusty Waze app as our guide, we climbed higher and higher into the clouds. The road seemed endless, but the promise of a hidden cache kept us going. And wow, was it worth it! A secret trail revealed itself, leading us to a vast amphitheater—so dramatic it felt like we’d stumbled upon a lost civilization.
The magic of Creux du Van still lingers, even after seven years. The amphitheater’s sudden appearance left a deep impression on our entire family. As the others made their way back to the car, I decided to extend the adventure and log a few more caches. Only later did I realize I had unknowingly found the second-oldest cache in Switzerland—a hidden piece of history that added yet another layer of wonder to an already incredible day.
Did You Know This About Creux du Van?
-
Limestone Formation: Around 200 million years ago, the Jura region was submerged under a warm, shallow sea. Over time, layers of sediment—including shells, coral fragments, and marine micro-organisms—compressed into thick limestone beds.
-
Glacial Carving: During the last Ice Age (approximately 100,000 to 10,000 years ago), glaciers sculpted the landscape, gouging out soft rock and accentuating the amphitheater's iconic semi-circular shape.
-
Freeze-Thaw Erosion: The amphitheater continues to evolve today. Water seeps into cracks in the limestone, and repeated freeze-thaw cycles slowly break down the rock. This process—along with gravity—causes chunks of rock to fall, widening the bowl over time.
-
Impressive Dimensions: Creux du Van spans about 1,400 meters (4,600 feet) in width and 150 meters (nearly 500 feet) in depth—big enough to house several city blocks. Standing at the edge gives you a dizzying view straight down into the vast, green basin.
-
Wildlife Haven: The area is a nature reserve, home to ibex, lynx, chamois, marmots, and a rich variety of alpine flora. If you’re lucky, you might spot ibex lounging on rocky ledges like seasoned mountaineers.
-
Microclimate Phenomenon: Due to its shape and orientation, the floor of the amphitheater can remain cool and damp even in summer, while the upper cliffs are dry and sunlit. It’s a natural microclimate showcasing several ecosystems in one place.
Whether you're a geology geek, a hiker hungry for views, or a treasure hunter chasing digital coordinates, Creux du Van delivers. It’s not just a place you visit—it’s a place that stays with you.
