The trail starts from watch tower in Kirkilai. Kirkilai Landscape Reserve – karst processes affected area. Here, and throughout all the karst area gypsum layers melt and occurs underground voids. An earth surface layer above them then falls in forming different size and shape karst ravines. They are commonly referred to as sinkholes, subsidence, slumps. Karst processes change the surface, deforms it and creates a unique landscape. When water fulfills sinkholes it becomes karst origin lakes. Kirkilai or Long lake – largest karst lake in Lithuania, it occupies 3,9 ha. The lake consists of 25 among each other merged and filled of water sinkholes. Lake maximum depth – 6.3 m, maximum width – about 120 m, length – 410 m. During the dry period lake water level decreases. Then some of the lake forming sinkholes become as separate lakes which merge again after rainier season or year. The most northerly – Lydis sinkhole – which opened up in 1915 is only about 50 m, but in some places depth reaches even 10,2 m. From a historical point of view the most interesting is Druskinė lake. Here, in order to find mineral resources, in 1874 one of the first Lithuania’s geological wells was drilled. These karst lakes are particularly attractive due to winding shores, picturesque peninsulas, isthmuses, lay-bys and islands. Kirkilai lake – the only one in the Baltic states rich with such a unique landscape. Due to the particular hydrological and hydrochemical conditions of those lakes fauna and flora is very distinctive. There are 46 species of zooplankton found in karst lakes. Botanical Institute scientists have revealed a unique ecology of this lake. Its uniqueness leads to calcium sulphate ions abundant saturated with water, and the stratification of temperature, amount of oxygen. Therefore, it is rich with sulfate-reducing sulfur bacteria which purple stocks can sometimes be seen with a naked eye. Due to this lakes are included in the European Union ecological network of protected areas "Natura 2000".
