Údolí Plakánek, Nature reserve in Dobšín, Czech Republic
Údolí Plakánek is a nature reserve near Dobšín in the Czech Republic, centered on a sandstone valley carved by the Klenice River and bordered by dense forest. A marked trail with information panels runs through the reserve, connecting Kost Castle at one end to the village of Střehom at the other.
The valley shows signs of settlement going back to the Stone Age, and during the Middle Ages it served as shelter in times of conflict. The sandstone quarries that opened here over the following centuries supplied building material for Kost Castle and shaped how the land around them was used.
The Střehom Water Mill, dating from 1516, is still in operation and draws visitors who want to see the old grinding mechanism at work. It stands as a living example of the valley's long connection to rural craft and everyday life in Bohemia.
The reserve can be entered from several points, including near Kost Castle and from the village of Střehom, so you can choose where to start based on what you want to see. Spring and summer offer the easiest walking conditions, when the paths are dry and the forest canopy is full.
The old sandstone quarries scattered through the valley left deep cuts in the rock that are still clearly visible today, revealing where stone was extracted over many generations to build Kost Castle. Walking past these abandoned pits, you get a direct sense of how much human work went into shaping what now looks like untouched nature.
