For roughly half the year, Lake Cerknica is a genuine lake, several kilometres across with boats and swimmers on its surface. For the other half, it can vanish almost entirely, its water draining down through sinkholes into the karst limestone beneath, leaving a wide grassy basin used for grazing and hiking until the water table rises again and refills it.
This cycle, driven by the porous rock typical of Slovenia's karst region, has puzzled and fascinated visitors since at least the 17th century, when polymath Janez Vajkard Valvasor wrote one of the first detailed scientific descriptions of an intermittent lake anywhere, work that later earned him membership of London's Royal Society. Today the basin is a protected nature reserve, and the birdlife that gathers when the water returns draws a steady trickle of dedicated visitors alongside the more general curiosity the disappearing lake attracts.
