Cognitive Trail “Barsuko ola” (Badger’s Hole)

In this rather short (700 m), but diverse in terms of terrain, geological trail you will not only exercise your legs, but also get acquainted with a unique phenomenon of Northern Lithuania – sinkholes that form when groundwaters wash out the underground gypsum strata. Going down the trail, up and down the steps and overpasses, you will see 13 different sinkholes – some of them rather simple, while others have a more complex form, some of them separate, while others interconnected from the outside and even the inside.
