Údolí Oslavy a Chvojnice, Nature reserve across Vysočina and South Moravian regions, Czech Republic
Údolí Oslavy a Chvojnice is a protected area stretching along the Oslava River for several kilometers from Náměšť to Čučice and including the Chvojnice tributary. The terrain features steep canyons with cliff walls, meadows, and forest patches that together create a mosaic of different habitats.
The area was already settled in the Middle Ages, as shown by the remains of several castles that once controlled the valley. The river section gained official protection status in 1974 to preserve the valuable geological formations and natural environment.
The valley has been a settlement zone for centuries, and scattered castle ruins still shape how people see this landscape. You can observe how humans and nature have coexisted here across different periods.
Sturdy footwear is needed as trails cross uneven ground and sometimes follow steep slopes. Visitors should expect wet or slippery conditions, especially after rain or near the river.
The river system has carved deep channels through hard granulite rock, creating spectacular cliff walls that sometimes exceed 30 meters in height. These rock formations provide ideal conditions for rare plants that thrive in such extreme settings.
