Stone mushrooms, Rock formation in Stolowe Mountains, Poland
Stone mushrooms are sandstone formations in the Stolowe Mountains featuring broad, flat caps balanced on slender pedestals of varying heights. These unusual shapes develop naturally as softer rock layers erode more quickly than the harder stone above them.
These formations developed over millions of years following glacial periods through continuous water and wind erosion on ancient sandstone plateaus. Scientific study of the structures began in the early 20th century to understand their distinctive shapes.
Local geologists organize educational tours to explain the erosion processes that shape these formations through seasonal water changes and wind patterns.
The formations are accessible via marked hiking trails in Stolowe Mountains National Park across routes suitable for different fitness levels. The best times to visit are spring through fall when the trails are dry and weather conditions are stable.
The mushroom shapes do not all develop at the same pace since water penetration varies with the seasons, driving erosion unevenly. This means you can observe different stages of formation within a short area, with some caps far older and more eroded than their neighbors.
