This is one of the most outstanding areas in the entire Baltic States with active underground waterways which still, to this very day, dissolve local gypsum rock. Parts of the area collapse regularly, and there are legends about all of this. Underwater rivers, streams, the so-called Karvės (Cow) cave, etc., can be seen in the area.
