Rising prominently within the heart of the Šumava National Park, the Luzný (Plechý) mountain ridge serves as more than just a topographic high point; it is a silent sentinel and a crucial geographical pivot in Central Europe. While the main peak, Plechý, barely crests the treeline, its slopes are defined by unforgiving granite and remnants of glacial activity, most famously the sheer walls overlooking the dark waters of Plešné Lake. More significantly, the Luzný mass straddles the Great European Watershed, dividing waters that flow north via the Vltava and Elbe rivers toward the North Sea from those that feed the Danube basin and ultimately empty into the distant Black Sea. This ancient divide gives the area a profound sense of isolation and raw ecological power. Today, Luzný and its surrounding peat bogs embody the wild heart of the Šumava, offering visitors rugged trails that trace the historically sensitive border between the Czech Republic and Germany, a landscape where thick, primeval forest meets subalpine heaths scarred by wind and time.
