Jurakalnis spur is a typical form of terrain formed by linear erosion. The process of linear erosion and its consequences – the erosive spur itself, the ridges and ditches where the springs are found - are clearly visible here. The most geologically valuable are the Jurassic rock outcrops, which are naturally accessible for research due to intense erosion. From the observation tower, a magnificent view of the Venta valley and its terraces can be viewed.
